Still mostly absent here. Anyway, FOSDEM was a blast as usual, and we're having a very good time in developing advanced platforms these days. The time of the OS is kind of over. Focus on simpler runtimes instead. See you in the Fediverse!

Running @oreboot_org on the XM8536D based NVR I'm hacking on, working just fine after expanding the binary with zeroes to ensure the stack memory is initially clear. 🥳 🦀

Got the UART address from the kernel decompressor via Ghidra.

I successfully did a `kexec` on the TP-Link M7350 v3 router via `cpu`, using kexec-tools:

cpu-tpl $KEXEC -cf arch/arm/boot/zImage

I.e., we can now @LinuxBootOrg!
We still need to gain NAND flash support and get the kernel to #boot without lk2nd directly, but the PoC is done. 👩‍💻

I reworked the kernel driver for the TP-Link M7350 v3 4G router to RGB565 color.
And I can now `cpu` into the device over USB to draw images and possibly send SMS from my laptop.
The @EFF Rayhunter project also runs on it. 👩‍💻
