Hello everyone. Another light week here. Let’s go over everything.

BeagleY-AI SD Card support

While hacking on my BeagleY-AI, I found that my HP SD card did not work with BeagleY-AI for some reason. On digging a bit further, some SD cards were not working on BeagleY-AI due to some issues with signal voltage switching on the am62x platform. This has now been fixed, as seen in the following patch series. By switching out the Linux kernel to mainline, I was able to get the HP SD card to work. So, the SD card compatibility of BeagleY-AI will improve soon.

BeagleBoard Rust Imager

BeagleBoard Rust imager got lots of love this week.

AppimageLauncher Problem

As pointed out by Jason here, the BeagleBoard Rust imager appimage is not usable with AppimageLauncher. The issue seems to be that appimagetool uses ZSTD compression now, while AppimageLauncher does not support it yet. Moreover, it seems like AppimageLauncher makes the appimage unusable. For now, the recommendation is to either remove AppimageLauncher or at least deactivate it for the BeagleBoard Rust imager.

More information regarding the upstream issue can be found here.

SD Card Flashing Performance Improvements

While the SD card flashing worked, it was much slower than the original bb-imager. After some tinkering with the buffer size while flashing and using parallel decompression of xz images, SD card flashing should be much faster (flashing time decreases by 57%).

It is still a bit slower than the original bb-imager (about 1 min), but it seems related to the internals of QFile, so that would be much more work than just a day.

Debian Packages

BeagleBoard Rust imager now builds Debian packages in CI using cargo-deb. While the goal is to eventually have an upstream package using debcargo, there is not much point until bb-imager-rs hits v1.0.0. Additionally, since debcargo only seems to support building stuff already present in cartes.io, it does not seem suitable for experimental builds (although I could be wrong about that).

Experimental Builds

Builds from the latest main branch are now pushed to Package Registry rather than just being stored as build artifacts. This makes grabbing the latest development version of bb-imager-rs much simpler.

Note: Only the most recent build is kept around.

Ending Thoughts

This was it for this week. Hopefully, this helps bring transparency regarding where the development efforts are concentrated, and how the community can help. Look forward to next update.

While the end of year holidays are fast approaching, my commitment to Linux hardware and open-source software remains and there still is a lot of interesting content to come this year still -- each and every day, without change for roughly a decade. Unfortunately though due to the (sad) state of the ad industry, many major companies focusing on the likes of Facebook/Meta ads, and the frequent use of ad-blockers by Linux/FLOSS readers make ongoing operations increasingly difficult. But if you'd like to show some love this holiday season, the Phoronix Premium "Cyber Week" / "Black Friday" special is now taking place so you can enjoy the site ad-free, native dark mode support, multi-page articles on a single page, and other benefits while hopefully allowing the site to continue for years to come...

The nRF54L15 DK is a development kit designed to evaluate the wireless SoCs of the nRF54L15, nRF54L10, and nRF54L05 wireless SoCs. These SoCs support multiple wireless protocols, including Bluetooth Low Energy, Bluetooth Mesh, Matter, Thread, Zigbee, and 2.4GHz proprietary protocols, with data rates of up to 4Mbps. The kit integrates the nRF54L15 SoC and provides emulation capabilities for the nRF54L10 and nRF54L05, enabling flexible testing and development across the nRF54L Series. The nRF54L series SoCs differ in memory configurations to meet various application requirements. The nRF54L15 includes 1.5 MB of non-volatile memory (NVM) and 256 KB of RAM for high-performance applications. The nRF54L10 features 1.0 MB of NVM and 192 KB of RAM for mid-range use cases, while the nRF54L05 offers 0.5 MB of NVM and 96 KB of RAM for entry-level designs requiring fewer resources. The kit is supported by the nRF Connect SDK and tools, providing access to [...]

In this off-topic post, I’m going to discuss some behind-the-scenes “fun” that may happen when managing the web server used to host the CNX Software website. From time to time, the server becomes unreachable, but I can still access its console, and notice a very high CPU load (over 100) on a VPS with four cores, while the CPU load is typically 0.5 to 2 under normal circumstances. That’s usually due to a DoS (denial of service), DDoS (distributed denial of service), or some bug I can’t identify. An easy way to solve this issue is to log in to Cloudflare and set the “Under Attack Mode” to on. It will show all visitors a JavaScript challenge the first time they visit the website, and the CPU usage typically drops back to normal level within a minute or so. That means I can access my website and so do regular [...]
