6 Things You Should Know to Elevate Your Embedded Linux Software Development

Getting started with embedded Linux development is now easier than ever. But to build a reliable, production-ready system, you need to go beyond the basics. Here are six critical areas to focus on to take your Linux-based embedded product to the next level.

1) Driver Development: Ensure Hardware Compatibility Before finalizing your hardware design, always verify whether Linux drivers are available for the components you choose. Most silicon vendors test their reference boards with Linux, so chances are drivers exist. But replacing parts to cut costs without checking driver availability can lead to time-consuming development efforts.

2) BSP Adaptation: Match Software to Hardware When working with a System-on-Module (SoM), you’ll need to tailor the BSP (Board Support Package) to your exact hardware setup. This involves configuring the Linux kernel and adjusting the device tree��— a special file that describes the hardware layout. Learning to navigate device tree files (DTS) is essential, even if it seems complex at first.

3) Boot Time Optimization: Speed Up System Start Fast boot times matter in many industries — from automotive to consumer devices. By default, bootloaders and kernels aren’t optimized for speed. You’ll need to tweak U-Boot settings, delay non-critical driver loads, and streamline startup scripts to meet performance expectations.

4) Power Consumption: Build Energy-Efficient Products Battery-powered products demand smart power management. Standard Linux kernels often don’t use all the SoC’s power-saving features out of the box. Techniques like clock gating, power domains, and peripheral shutdowns require deep hardware-software collaboration to extend battery life.

5) Real-Time Requirements: Add Determinism If Needed Linux isn’t a real-time OS by default. For soft real-time tasks, standard Linux may suffice. But when you need hard real-time behavior, tools like Xenomai can be integrated — though they require careful driver and kernel-level modifications.

6) System Updates: Keep Your Product Secure & Up-To-Date Over-the-air (OTA) updates are essential today, but Linux doesn’t offer a one-size-fits-all solution. You’ll need to handle updates for the bootloader, kernel, and root file system, often using partitioning techniques like dual-image systems. Done right, it ensures system integrity even in cases of power loss during an update.

The Takeaway While Linux-based embedded systems are easier to launch than ever before, truly robust product development still requires thoughtful planning and technical know-how. The good news? If you know where to focus — like the six areas above — you can streamline development, reduce risks, and get to market faster.

So, about Linux. Do you have a phone that uses Linux? Is there one out there that can access tumblr and be reasonably usable? I'm just sick of Apple and Google's BS and want an opinion from someone in the know.

technically: android is built on linux

less pedantically: i personally have a google pixel with stock android because it's the least bloated and i don't trust most other manufacturers to not put dumb bullshit on my phone.

if you want a linux phone then i've heard good things about the pinephone. here are the operating systems it supports: https://pine64.org/documentation/PinePhone/Software/Releases/. note that a lot of the OSes don't have full support for all of the device features like bluetooth, and there won't be android app support out of the box. you'll have to use something like waydroid and idk how good the compatibility is.

if you want something closer to the normal android experience, grapheneOS might be up your alley. caveat: there is very limited device support; they basically only have official support for google pixel devices: https://grapheneos.org/faq#device-support. google play is disabled by default but you can enable the sandboxed version of it to install tumblr.

if you see other custom ROMs or AOSP-based OSes, you should do some research to make sure you're comfortable with the developers and the security for them. grapheneOS is generally well regarded and most other projects don't have anywhere near the level of focus on security. (less pussyfooted answer: i wouldn't use them.)

Massive Backdoor Infection Hits 1.3 Million Android-Based Streaming Devices

A newly discovered malware infection has raised alarm bells by affecting an estimated 1.3 million Android streaming devices running an open-source version across almost 200 countries. The malware, dubbed "Android.Vo1d," has successfully backdoored these Android-based boxes by inserting malicious code into their system storage areas, allowing for potential updates with additional malware via command-and-control servers at any time.

Scope and Impact

Security firm Doctor Web reported the widespread infection on Thursday, highlighting the extensive reach of the Android.Vo1d malware. The affected devices are operating systems based on the Android Open Source Project (AOSP), a version overseen by Google but distinct from the proprietary Android TV used by licensed device manufacturers. Google representatives have confirmed that the infected devices are not running the official Android TV OS, emphasizing that these are "off-brand devices" without Play Protect certification. This certification process involves extensive testing to ensure quality and user safety. Confirm your TV is running Android TV OS by using the guide posted here.

Unknown Infection Vector

Despite their thorough understanding of the malware and its widespread impact, researchers at Doctor Web are still uncertain about the exact attack vector leading to these infections. They have proposed several possibilities: - An intermediate malware exploiting operating system vulnerabilities to gain root privileges - The use of unofficial firmware versions with built-in root access - Outdated and vulnerable Android versions susceptible to remote code execution exploits - Potential supply chain compromises, where devices may have been infected before reaching end-users

Affected Devices and Variants

The infection has been found on several TV box models, including: TV box model Declared firmware version R4 Android 7.1.2; R4 Build/NHG47K TV BOX Android 12.1; TV BOX Build/NHG47K KJ-SMART4KVIP Android 10.1; KJ-SMART4KVIP Build/NHG47K Researchers have identified dozens of Android.Vo1d variants, each using different code and planting malware in slightly different storage areas. However, all variants achieve the same result: connecting to attacker-controlled servers and installing components that can deploy additional malware on command.

Infection Characteristics

The Android.Vo1d trojan modifies several system files and creates new ones to ensure persistence on infected devices. Key changes include: - Modification of the install-recovery.sh script - Alteration of the daemonsu file - Creation of new files: vo1d, wd, debuggerd, and debuggerd_real These modifications allow the malware to anchor itself in the system and auto-launch during device reboots. The trojan's main functionality is split between two components: vo1d (Android.Vo1d.1) and wd (Android.Vo1d.3), which work together to maintain the infection and execute commands from the control servers.

Geographic Distribution

Geographic Distribution of the Android.Vo1d infections The infection has spread globally, with the highest number of cases detected in: - Brazil - Morocco - Pakistan - Saudi Arabia - Russia - Argentina - Ecuador - Tunisia - Malaysia - Algeria - Indonesia

Detection and Mitigation

Identifying infected devices can be challenging for less experienced users. Doctor Web recommends using their antivirus software for Android, which can detect all Vo1d variants and disinfect devices with root access. More technically inclined users can check for indicators of compromise provided by the security firm. The incident also highlights the risks associated with using non-certified Android devices and emphasizes the importance of regular security updates and proper device vetting. As the investigation continues, it serves as a stark reminder of the ongoing challenges in securing the diverse ecosystem of Android-based devices in the market. Read the full article

If Chromuim isn't Chrome to you, then would you say that the AOSP isn't Android? Or, that some of the OSes built upon it aren't Android, such as, say, Amazon's Fire OS or whatever facebook would call the OS running on their Portal and Quest devices, even though they all run Android at their core, much like how Chrome is Chromium at heart?

I don't think that's a fair comparison to make. chromium is simply the engine chrome is based on; chrome is chromium, but chromium isn't chrome
