Broke: randomly flipping nodes to `okay` and rebuilding until it works, grepping `build/zephyr/zephyr.dts`...
Based: Dan saves us all 🙏❤️
Zephyr is so good, I used it to test a non-Zephyr port today 😍 instead of spinning up a quick sample app. Zephyr makes everything so easy!
Wow, what an adventure! It's always DNS as the saying goes 😅 great post @danielmangum.com !
in case it's useful in the future, @memfault.com provides native modern trace export for nRF91 chips, built into the nRF-Connect SDK (uses the Memfault Custom Data Recording feature- also supports the MTB!)
**The Miserable State of Modems and Mobile Network Operators**
New post in which I recount a winding debugging journey to identify the root cause of a modem connectivity issue, and lament the closed ecosystem of cellular network infrastructure and firmware.

goto was enough for our grandparents, only hipsters use anything else
😂 I'm cooked
Here's an interesting FreeRTOS to Zephyr migration guide that AMD published this week. At the very least, the intro has a useful table that links to relevant sections of the docs for each platform. The side-but-side code examples are handy too.

Dan no 😄
old article but really nice approach to heterogeneous multicore-

This was always surprisingly confusing on the OG thingy91, ty Dan!
A fun game for kids to pass the time during car rides- guessing hexadecimal color codes! "What's blue plus red?" #800080! fun for ALL ages! And your driving partner will DEFINITELY NOT be appalled by you 😍
TIL that Cortex-M/Thumb has specific "jump table" instructions, TBB (one byte offsets) and TBH (two byte offsets)

It's awesome for networked stuff! Much nicer than the old x86 target it replaced 👌
The QEMU board targets are sooo useful, I use them multiple times a day most days!

Memfault coredump showing multiple CPU backtraces
One of the fun projects I was lucky enough to work on recently at @memfault.com - adding multi-core support for ESP32 coredumps! Nothing like some quality time with the Xtensa architecture reference manual 🤓
hearing a lot about AT protocol, MY TIME IS NOW

😄 nice to see the non-Linux users among us getting a leg up!
before `--device` existed I used to use the quite appalling (BUT EFFECTIVE) `-v /dev:/dev --privileged` approach, which is pretty awful but it definitely works 😅
Hard to see in this picture, but my dryer control board has like a full cm of conformal coating 😮 maybe it helps dampen vibration too?
Lucked out with an early taste of winter last week!

**This Website is Hosted on Bluesky**
This weekend I found myself digging through the AT Protocol specifications and the Bluesky Personal Data Server (PDS) implementation. In doing so, I discovered that I could setup a website that is fully hosted on Bluesky.
