wait you made a genesis controller that's so fucking cool

Hell yeah I did!! I was making custom arcade sticks for a while with my best friend. We made one as a proof of concept for a decently popular speedrunner and when he used it on stream a number of other streamers contacted us looking for controllers. One was a classic Sonic runner that asked for a Genesis controller and I was like "Sure, that sounds like a fun challenge!"

It wound up being... Ultimately not that bad?? But it required a lot of experimentation and learning on my part the details of which are about to be inflicted upon you because you dared to ask

When I started I looked at the Genesis controller pinout my first thought was "oh, that's super easy" - it's 9 pins: 2 that carry power, 6 that carry data, and one SELECT line that changes which pins represent which buttons. This is a hilariously easy C program to write so I got the Pico SDK set up and cranked it out, flashed it using my janky homemade picoprobe carrier, and immediately ran headfirst into problems.

See, my thinking was along the lines of "The Pico runs at like 8x the clockspeed of the Genesis, I just need some level shifters to convert between 3V and 5V signals and we're golden" and that was... Actually mostly true. However, every like 20-30 seconds it would produce either phantom inputs or drop out entirely for half a second or so, which is just laughably unacceptable for speedrunning purposes.

I tried pursuing that implementation for a while - down to comparing signals from my controller and a stock Genesis controller with an oscilloscope - before I ultimately decided that it wasn't worth the effort. I think the final straw was that it was basically working in game but the everdrive menu wouldn't work with it at all?

It was at this time that I finally decided to crack open an old Genesis controller and look at what integrated components (ICs) it used to try to reverse the circuit. The one I had was worthless - after copycat controllers started showing up on the market back in the day SEGA switched all their official controllers to use a single proprietary chip that they produced specifically for this purpose. They even put a glob of some dense cured resin shit over the chip and the traces around it to make it impossible to lift off the board or reverse.

I found a couple grainy scans online of REEEEEEALLY old controller models that and could sus out a multiplexer chip and that's about when things started making sense to me. Previously I had only worked with digital controller protocols like xinput (Xbox/PC) or joybus (N64/GameCube) but that was a level of sophistication only achieved later in the development of game consoles - there is no protocol on the Genesis.

There are 9 pins on the Genesis main board (18 for both controller inputs) that are connected directly to the pins on the controller port. Your controller takes a Long Ass Wire and connects those pins to buttons on the gamepad, with a multiplexer sitting in between so it can swap out a couple buttons based on the SEL line. It didn't matter how fast my chip ran because 1. This is gonna be a noisy signal and measuring it digitally is going to be imperfect, and 2. Literally any latency whatsoever is a problem because this is going to be read at a hugely variable rate. This has to be implemented with logic gates.

For those of you that have a college education (in say, comp sci or comp eng or electrical eng or mech eng) this is likely not that much of a challenge. For me, as a professional software engineer, expressing the logic was trivial:

(I know I probably could've done that with just NAND gates (and the inverter is COMPLETELY unnecessary) but a girl loves easy-to-read circuit diagrams that directly reflect the intended logic)

But manufacturing the damn thing?? THAT was the hard part. My dumb (white, self-taught) ass had never worked with ICs before, so my first draft was literally just sticking all of these together with no resistors or capacitors in there whatsoever. I had basically just made an antenna - moving the controller around in space (or bearing near enough to other electronics) caused voltage fluctuations which resulted in erratic signals being sent to the console.

My SECOND draft however - after consulting with an Actual Electrical Engineer ™ and learning the benefits of capacitors and resistors in logic circuit design - worked fucking great. According to EE friend it was slightly overbuilt - I had given each IC its own power input smoothing capacitor located right next to those pins when just one would likely suffice, and similarly every input pin got its own pull-up resistor - but I was 100% okay with that. Overbuilt is better than underbuilt and this is a handmade low-volume good, a couple cents on electrical components made no meaningful budget impact.

One "oh god fuck doing this by hand" and run of FreeRouting's Auto Router later we had ourselves a PCB layout!

I placed an order for 3 of those from our good friends at OshPark and then it was just a matter of assembly! Soldering it together was easy as hell, the final product ended up looking this (short a few capacitors I was still testing to see if I needed)

Then it was time for assembly!! The client requested black acrylic panels to kind of resemble a B0XX so I took our CAD model of the controller and I added circuit mounting holes to the bottom panel, cut each panel out with my laser cutter, and started piecing the panel joints together with a tight friction fit. To seal the joints I carefully filed the seams of each edge until I had a rounded and near-seamless corner filled with ground acrylic and then used a very fine plastics glue to flood the micro gaps in there and give it more long term sticking power. Notably I didn't do this on the bottom panel as it's meant to be popped on and off by the user if they wanted to replace the buttons or wiring harnesses or something.

Then...it was done!! Because of the raw amount of fuckery involved in this process (and the fact that this wasn't my main source of income/I was selling my house/meeting my fiance/MANY other things) it took about a year between me receiving the commission and actually shipping the finished product, but I'm really proud to say that we did do it and the client LOVES it!!

#aripost #asks #on the one hand I'm sorry for inflicting this on everyone's dash #but on the other hand I'M REALLY FUCKIN PROUD OF THIS THING AND YOU HAVE TO LOOK AT IT OKAY

CRIMSON SHADE

Chapter 10

Weddings and Vendettas

He's a wolf in disguise

But I can't stop staring in those evil eyes

- ( The song of the chapter is 'Monster' by Lady Gaga)

Khushi sits silently at her desk, gently caressing the bandage on her wrist. With every blink, her eyelashes stir, each moment bringing a new flash of the same memory, vivid and unrelenting.

Rain.

Raindrops.

Raindrops clinging to long lashes.

Lashes framing beautiful brown eyes.

Fingers clutching a coat lapel,

Fingers circling a delicate wrist.

Teeth clenched around a glass piece.

Lips curled into a barely-there smirk.

Buaji's voice cuts through the trance. "Haire Nand Kishore, you're drenched! You'll catch a cold!" she fusses, rubbing a towel through Khushi's hair. Her eyes dart to Khushi's wrist, and a gasp escapes her lips. "What happened to your wrist?"

"It's just a tiny cut, Buaji. Don't worry."

"Are you feeling dizzy?"

"Why would I feel dizzy?"

"Because the sight of blood makes you dizzy, bitiya. Are you alright?"

"Oh," Khushi says, a trace of bitter amusement in her voice as she remembers the younger version of herself, the one who would faint and vomit at the mere sight of her own blood. Buaji doesn't know, that Khushi died a long time ago. The girl who once crumbled at the sight of red vanished the day she ended a man's life. Blood doesn't bother her much anymore. She's learned how to control it. Like she's learned to control the feelings coursing through her blood.... rage, fear, desire....

Except when 'he' is near.

One particular Armani-clad individual still makes her blood boil, agitating her to the point that she forgets all of her old phobias.

She can't decide if that's a good thing or a bad one.

It can't be anything but disastrous.

He is poisoning her blood.

When Khushi steps out of the shower, wearing her favourite pajamas with towel wrapped loosely around her hair, she sees Buaji rummaging through her cupboard, pulling out every designer outfit she owns.

"What are you doing, Buaji?"

"Didn't Mr.Jha tell you, bitiya? We are going to Gurgaon."

"For what?"

"The Oberoi's eldest son is getting married!...what you guys tell it these days..oh huh..'destination' or something. Obviously, all of Delhi's elites will be there. So, Mr.Jha is taking us with him."

"When?"

"As far as I know, we're supposed to prepare for a two-day stay there, this Saturday and Sunday."

Oh, Sucks.

This puts such a damper on her 'find-the-evidence-and-get-the-hell-out- of-here' project. Two days of mundane chatter, ridiculous cosplays and forced pleasantries. Fake smiles and empty wishes will be used left, right and centre. Weddings bore her to death. Why does she even need to attend? She doesn't know the bride or groom.

Uff..

But of course, Mr.Jha is busy trying to establish every connection he can before his election. Shakti Singh Oberoi isn't just one of the richest men in the city, Mr.Jha's real interest probably lies in the fact that the Oberoi family has a long list of people in Parliament right now. It's always about power and politics.

Buaji holds up two lehengas in front of her, waiting for Khushi to choose.

"Pick whichever you like, Buaji. I don't care."

"What will I do with her? Fine, I'm picking the red one," Buaji huffs.

Khushi rolls her eyes. Buaji can't be more predictable. "Not the red one."

"Why? Red looks good on you, bitiya."

"I'm kind of hating the red colour nowadays. What about pick the purple one."

Khushi connects her phone to the charger as buaji keeps sorting her clothes. She wraps herself in her blanket and drifts off to sleep.

But brown eyes invade her dreams.

Vivid, relentless, and inescapable.

It's insufferable. He is insufferable. That egoistic man is not letting her sleep at night. Khushi throws off her covers and sits up in her bed, dragging her laptop toward her. She will teach him a lesson. What leverage does he have against her again? A CCTV footage. She will hack his phone and erase that footage.

She fiddles with her phone. She has his number, right? He's sent her a text with that video. With a few taps, she searches for his contact.

What the fuck...

Of course, it's encrypted. But it's an encryption she can break.

"Game on, Mr.Raizada. Since the day we met, all you've done is threaten me and pin me against the wall. Now you've crossed your limits. You're pinning me in my dreams as well. I will show you what messing with me will cost you."

Her eyes gleam as her fingers fly across the keyboard, the adrenaline coursing through her veins. A smile stretches across her face as she cracks the code and is almost one tap away from erasing all the information from his phone when her laptop hangs. The screen scrambles with a warning about virus detection, and she curses under her breath as the laptop goes into self-preservation mode.

Frustrated, she rubs her eyes. Her phone beeps with an incoming message. An unknown number.

'Nice try, little bird.'

For the next few days, Khushi looks like a zombie. Not only is she plagued by the same dreams--or nightmares, as she prefers to call them--but nothing interesting is happening in her father's study either. Apparently, the wolves haven't yet discovered who killed their beloved daughter, so the serpents are safe, at least for now.

All of these make Khushi ponder a certain offer. It doesn't feel so bad sitting in her own bedroom, frustrated with empty search results and the impending mind-numbing conversations with a bunch of unknown wedding guests. An IT expert at a tech company-her classmates would salivate over a job like that straight out of college. She knows it's not her qualifications that are getting her this opportunity; it's because of something she can do for him.

Then there's what he said about providing evidence against her father. Ugh... why does she become such a fireball in his presence? He was right. She asked all the wrong questions. Instead of inquiring about the evidence he mentioned, how he got it, and how she could use it, she let his threats get to her and lost her shit entirely.

"I expected more from you, Khushi," she chides herself, banging her head against her laptop. It's a new task for her now, a new skill to learn: how to keep her cool in the presence of Mr.Arnav Singh Raizada.

But she doesn't have his number. How will she contact him? The encrypted number is a one-way street; she can't text him back.

There goes the offer. Now she has to wait for another chance meeting with him to tell him she'll work for him, but only if she can lay down some conditions of her own.

And the worst part? She has no idea when or if she'll meet him again in the near future.

The uncertainty gnaws at her, leaving her more frustrated than ever as she packs her bag for the wedding she is going to attend. The wedding is set in a luxury resort just on the outskirts of the city, no more than a two-hour drive away.

As she tosses clothes into her trolley, her mind races with scenarios, each more outrageous than the last, where she meets him again and tells him about her accepting his offer. She can already imagine the smug look on his face, that infuriating smirk that makes her want to scream, punch and wipe that smile from his face all at once.

But beneath the annoyance, there's a spark of determination. If she can just see him again, she'll find a way to turn the tables. She won't let him intimidate her or pin her down anymore.

Then her thoughts shatter as ice water of realization washes over her. What's the point of thinking about the offer or accepting it? Her father would never allow her to work, and neither would Mr.Jha. She can never do it anyway. She grits her teeth and snaps her trolley shut.

Khushi sits stiffly at the long banquet table, flanked by her father and Mr.Jha, her hands resting on her lap beneath the lavishly decorated tablecloth. The glittering wedding hall around her feels suffocating, the loud hum of chatter and laughter grating against her nerves. Her father, seated to her right, exchanges polite conversation with the other guests, his tone authoritative, as always. To her left, Mr.Jha, the epitome of perfection, flashes his charming smile to those who pass by, looking every bit the polished, well-bred man her father adores.

But Khushi feels disconnected. She is drowning in a world of pretension and formality, a world where every word is calculated, every action rehearsed. The air is thick with the scent of expensive perfumes and freshly cut flowers, but it only reminds her how out of place she feels here.

The fabric of her lehenga digs into her skin. She wishes she could tie her hair up, but the makeup artist had styled it in loose waves cascading around her shoulders. The heavy jewellery weighs her down, making her body ache.

She should feel honoured to be seated between these two powerful men, her father's pride and her fiancé's polished charm surrounding her. But all she feels is trapped. Her thoughts swirl with a mixture of resentment and exhaustion. The glittering lights, the perfect smiles, the endless small talk, it all feels hollow.

Her gaze flickers across the room, trying to avoid the eyes of those who expect her to smile, to play the role of the dutiful daughter and future wife. But beneath the calm exterior, her heart races. Her body is present, but her mind is far away.

She softly drums against the linen, as Her eyes drift up, almost instinctively, and there he is.

So the Eagles are here as well, huh?

He is indeed an Eagle through and through, his presence alone exudes power. He’s draped in a deep brown suit-type sherwani, she isn’t quite sure what they are called. The tailored fabric clings perfectly to his imposing frame, every seam accentuating the breadth of his shoulders and the straight line of his posture. The deep, almost regal brown not only adds a richness to his look, but also brings out his eyes even more. She huffs closing her eyes.

He might be an asshole, but he's the kind you can't help but stare at. The traditional attire only adds to his appeal, making him infuriatingly hard to ignore, despite the attitude that comes with it. His presence demands attention, and no matter how arrogant he seems, there's no denying he's dangerously attractive.

His dark gaze fixed on her from across the room. His expression is unreadable, but the intensity behind his eyes is unmistakable. A shiver runs down her spine. A spark ignites in the air between them that no one else seems to notice. She quickly looks away, her pulse racing.

But the pull is undeniable. She glances back at him, catching his gaze once more. She was looking forward to this moment, the chance to meet him face-to-face once more. Her lips curve into a small, almost imperceptible smile, one she tries to suppress but can not. It doesn't escape him. One of his eyebrows lifts up.

And her breath catches. And in that split second, Khushi feels like they are the only two people in the room, locked in a battle of unspoken words and unreadable expressions. But that slight lift of his brow, that glint in his eyes-it tells her he knows. He always knows.

From the corner of her eye, she sees the wedding planner she was introduced to earlier, guiding the Eagles toward the table where she sits. Her heart skips a beat as she watches the group approach slowly. As soon as the first one arrives, the atmosphere shifts. One by one, the members of the Eagles come into view, their faces hardening the instant they spot who is already seated. It takes only a split second. A cold realization ripples through the group. This was a mistake. The wrong families had been seated together.

The wedding planner, blissfully unaware of the gravity of the situation, smiles brightly at all of them. She tenses, her eyes flicking toward Mr.Jha, who sits rigidly beside her. A conversation runs through her mind.

"He said he was sure about who killed his father. But how could that be? The person he's talking about was just a boy back then...what, 14 or 15?"

Her eyes snaps back to the brown one.

Oh no!

The tension becomes palpable, thick enough to choke on. Guests at the table shift uncomfortably in their seats, casting uneasy glances at one another.

Mr.Rathore exchanges a sharp glance with Mr.Raizada before his gaze slid to her father, then to Mr.Jha, his lips pressed into a thin line, the displeasure clear despite his outward calm. "Well, this is.....unexpected," Mr.Rathore muttered, his voice cold, eyes darting between the Serpents already seated at the table.

Tension spikes when one of the men beside Mr.Raizada, makes a move to grab the collar of the wedding planner, his temper threatening to erupt. But Mr.Raizada raises a hand, a silent command, and the man freezes. Without breaking his composure, Mr.Raizada pulls a chair out in a smooth motion and gestures Mr.Rathore to sit. Then, with deliberate calm, he pulls out the chair beside Mr.Rathore and sits down himself. He leans back slightly, crossing his arms over his chest. "Forgive the wedding planner for the misunderstanding, Rakesh," he says, with his unsettlingly neutral voice with no malice, no hatred, no rage, no irritation, nothing. "After all, we are all friends here, aren't we?"

Her pulse quickens. She doesn't need to glance at her father to know his jaw is clenched, his fingers likely curled into tight fists beneath the table. And yet, mr.Raizada remains disturbingly calm, too calm. His eyes scan the faces of the serpents, not a single emotion flickering across his features. If anything, he seems amused, as if he's daring them to react, to make the first move.

Mr.Jha gives a curt nod,"Of course," he bites out, faking a smile. There aren't only the members of the Serpents and the Eagles, there are also Mr.Jha's political allies. He has to save face.

Across from her, the brown eyes briefly meet hers before he addresses everyone, "I trust we can make it through a few hours without incident," his voice low but carrying enough weight to silence the murmurs around the table.

The Eagles exchange wary glances as they hesitate for a beat before taking their seats. She watches across from her Junior Rathore quietly takes his place beside Mr.Raizada and then the two girls she saw at the restaurant earlier slide into the seats beside him. One of them, petite, with big dark eyes flashes her a small, secretive smile. The other, with glossy dark hair and a bit more confidence, sneaks a wave as though they're old friends sharing a private joke.

Strange. She frowns. Yet her lips twitch at the surrealness of the situation.

��Oh, darling, you’re here! Sorry, I’m late,” a singsong voice says as a freshly manicured finger trails across Mr.Rathore’s shoulder. A gorgeous woman in a black saree slides into the seat beside him. Ah yes, Mr.Rathore’s girlfriend, Sheetal Kapoor. The envy of all the men in the society.

Slowly, they begin to converse among themselves, and the atmosphere around the table settles back into a semblance of normalcy. Conversations ebb and flow as laughter punctuates the air. Khushi takes a sip of her cold drink, letting the chill pass through her, while her gaze drifts across the table.

There he is, blatantly staring at her, swirling his drink in the glass with a casual nonchalance that betrays his boredom. The corner of his lips quirks up.

She can't help but feel the heat rising in her cheeks under his unwavering gaze. It's as if he's dissecting her every move, and for a moment, she wonders if he can read her thoughts. With a quick glance, she meets his eyes, holding his gaze for a heartbeat longer than necessary before looking away, trying to regain her composure.

She rolls her eyes internally, refusing to let him see how flustered he makes her. "So charming," she mutters under her breath, hoping the sarcasm will help ease the tension brewing between them. But inside, she feels that familiar spark igniting again, making her pulse race.

She steals another glance, catching him smirking now, that infuriatingly confident smirk that tells her he knows exactly what effect he has on her. The table buzzes around them as the two of them are locked in a silent battle of wills.

The conversation around them shifts into the importance of female education, equality and how Mr.Jha is doing excellent job in this regards, but she has tuned it out.

She places her glass almost defiantly and crosses her arms, looking at him fully, refusing to look away. His smirk stretches further. It's smooth and teasing. He's savouring every second of their little game.

But the game is cut short when a woman, one of the wives of a business associate seated with the Serpents, turns her attention to Khushi with a warm, curious smile

"What about you, bitiya? Are you attending college?"

She blinks, breaking her staring contest, and smooths the napkin over her lap. Her composure slips back into place. She clears her throat, quickly scrambling to switch gears from their wordless duel to the polite conversation at hand.

"Oh, um..." she starts, offering the woman a polite smile. "I've graduated recently from IIT Delhi. Computer Science"

"She’s graduated with honours. We are very proud of her." Mr.Jha adds to their conversation.

The lady smiles radianty at her , "Oh, that's excellent. A girl in Computer Science. I'm so intrigued. Are you doing anything right now? Are you applying for higher education? Masters or PhD or anything else?"

"Umm.... I guess I'm now on a creative hiatus...exploring few..... personal interests."

Out of the corner of her eye, she catches his raised eyebrow across the table, a knowing smirk tugging at his lips. Then a sinfully deep voice joins the conversation as well. "In other words, you're neither studying nor working," he comments flatly.

"There are other things I do, of course." she feels her ear pinking as she sips her drink to control the verbal lashing that begs to come tumbling toward Mr.Raizada.

"Do share," he taunts in mock fascination. "What do you do, Miss Gupta? Besides collecting degrees just to keep them gathering dust, I mean." The table falls silent, not a good kind of silence.

"I'm sure, Miss Gupta will have a bright future. She is a brilliant girl and will do wonders to the society alongside her fiancé, Mr.Jha. They will be such an extraordinary couple," Mrs.Rastogi intervenes.

"Yeah, I'm sure, they will. So, tell us, Miss Gupta, what are you planning to do with that degree you get...with the money of the honourable tax payers of this country....besides indulging in hobbies and attending galas..." her eyes narrow as her fingers tightens around her glass, ".....or is it keeping the fashion industry afloat by purchasing enough clothes to dress half the country? If so, thank you in advance by the way, for investing in our business."

"I'm going to kill you, Mr.Raizada," she mutters silently clenching her teeth.

The poor lady, Mrs.Rastogi comes to damage control as she nervously adds, "The IT field has flourished in the last few years. I'm sure she'll find something to contribute to that. Bitiya, what are you planning to do next? Work, perhaps?"

Khushi hesitates, not sure how to respond to that question in front of everyone. Before she can find the right words, the infuriating man cuts through the conversation."Well, that depends, doesn't it?" His gaze flickering to her father and then Mr.Jha, before finally landing back on her. "I suppose certain permissions are required before any plans can move forward."

The words are casual, but the barb is clear. Her polite smile wavers just a fraction.

A particular clinking sound of curtilary draws her attention to Mr.Jha. His expression is calm, but his knuckles whiten around his fork. "Actually, that's not true. I'll let her to do anything she wants." Mr.Jha replies smoothly, his tone polite but edged with barely concealed irritation.

"You'll let her...." He quotes him and smirks leaning slightly forward , "...like I said, she needs your permission to do a job if she wants. Where's the equality in this again?"

"Khushi's future is important to all of us. We only want what's best for her. She has full autonomy to do whatever she wants to do." Mr.Jha says through gritted teeth.

Her eyes meeting the brown ones. His gaze is sharp, as though he's daring her to respond. But she remains silent.

"Oh, that's wonderful to hear, Mr.Jha. How reassuring it is to know that our future leaders practice what they preach! Supporting your fiancée in her career sets such an extraordinary example for the young generation of this country," the lady gushes on and on and on.

"Yes, thank you, Mrs.Rastogi," Mr.Jha responds politely, meanwhile shooting daggers across the table. "Empowering women is a central theme of my campaign. After all, charity does begin at......"

"Actually, Dad," Khushi cuts in with a slightly higher tone, turning fully toward her father, "I have been thinking of sharing this with you for a couple of days. I have an offer from a tech company. Paragon Tech.....I think, I'll consider that offer. What do you think? It's a good company, right?" She asks faking a bright, enthusiastic smile. It's an opening. She had to take this chance.

"Yes, it's a good company. You can work there if you wants, sweetheart." His father says before pursing his lips. "We'll always support her." her father continues, nodding at Mrs.Rastogi while brown-eyes looks like he’s just won the argument.

Everyone returns to their starters as the conversation dies down, but an urge lingers in the air. An urge to strike back.

"You know, Mr.Raizada," Mr.Jha starts with a casual tone. "I heard a very amusing story a few days ago... one of my bodyguards just mysteriously found himself unconscious in your presence."

And that infuriating smirk is back on his face as he wipes his mouth with a napkin. "My condolences. You need better security, Mr.Jha, with better skill to remain on their feet.....and better manners."

Mr.Jha’s jaw tightens, but before he can retort, Her father addresses the brown-eyed man across the table with a hard look. "Mr.Raizada, have you forgotten your manners at home?"

Something darker flickers in the caramel-brown orbs, "On the contrary, Mr.Gupta, I remember them quite well, much to your future disappointment."

She can feel both Mr.Jha and his father's rage toward the brown-eyes radiating off them in waves. And she’s sitting in the centre of these three men.

The servers gathering around the table help bring the tension down a few notches. Mr. and Mrs.Rastogi attempt to extinguish the brewing disaster by shifting the conversation to lighter topics, asking Mr.Jha about his political campaign and other matters.

And all this time, his eyes have been on her. Discreet this time, not very obvious.

She feels like burning from the inside out, and all he does is watch, his expression unreadable. It drives her mad, to the point she wants to scream, but instead, her voice comes out quieter as she responds to Mrs.Rastogi's other questions.

After a while, he leans in, his lips moving silently as he whispers something to Mr.Rathore. And then he leaves the table, leaving behind a empty chair in front of her.

The chair remains vacant when their main course is served, even through dessert.

Without his brown eyes all over her, she feels strangely empty too, just like the chair does.

And it’s a dangerous feeling.

A feeling that could ruin her.

Understanding the 4 Core Components of an Embedded Linux System

Before diving into how to build a complete embedded Linux system, it’s important to know what major parts make up the system itself. A good way to understand this is by looking at the boot process — what happens when you power on a device like an embedded controller, industrial gateway, or smart gadget.

Each component plays a specific role in bringing the system to life, step by step. Here's a simple breakdown of the four essential parts of an embedded Linux system:

1. 🧠 Boot ROM – The Starting Point Inside the SoC

The Boot ROM is the very first code that runs when you power on your embedded device. It’s stored in read-only memory directly inside the System-on-Chip (SoC) and is similar to the BIOS on a standard computer. Although it's locked and can't be changed, it can react to external configurations (like boot pins) to decide where to load the next stage from – such as an SD card, eMMC, NAND flash, or even over UART/serial.

Some Boot ROMs also support secure boot by only allowing signed software to load next, adding a strong layer of security to the embedded system.

2. 🚀 Bootloader – Initializing the Hardware and Loading the Kernel

After the Boot ROM finishes its job, it passes control to the Bootloader. In many cases, the bootloader itself runs in two steps:

First stage: Prepares the system by initializing the RAM (since it's not ready right after power-up).

Second stage: Loads the Linux kernel from a chosen storage device or over a network (useful during development via TFTP).

Modern bootloaders also include features to:

Flash firmware or kernels onto memory devices like NAND or eMMC,

Test hardware components like I2C/SPI, RAM, and others,

Run Power-On Self-Tests (POST) to ensure system stability before launching the OS.

Popular bootloaders like U-Boot are often used in embedded Linux development for their flexibility and wide hardware support.

3. 🧩 Linux Kernel – The Core of the Operating System

The Linux Kernel is the brain of the system and is responsible for:

Talking to the hardware (drivers for peripherals),

Handling system tasks like scheduling and memory management,

Creating a stable environment for your applications to run.

It acts as the bridge between the hardware layer and the user space, making it possible to develop portable embedded applications that don’t rely on the specifics of the underlying board.

4. 📁 Root File System – The Application Playground

Once the kernel is up and running, its next task is to mount the root file system — the place where all applications, scripts, and shared libraries live.

Creating this from scratch is complex due to package dependencies and compatibility issues. That’s why tools like Buildroot, Yocto Project, or OpenEmbedded are used to automatically build and manage the root filesystem.

These tools help embedded developers customize and maintain a lightweight and reliable file system tailored to their device, ensuring consistency and performance.
