#barebox is totally awesome, just got to toy around with it a little, as they provide a TinyEMU WASM demo for it -> https://www.barebox.org/demo/?graphic=0 , while I hack on packaging it as a bootloader for guix (building/configuring it works exactly like kconfig/kbuild so coming up with a package isn't too difficult)

If you are at #39c3 and are curious about how kernel and firmware use #OpenFirmware device tree to discover hardware and how @barebox (and other bootloaders) use it when booting Linux, come by tomorrow at 13:00 at the open source firmware assembly in Hall 3 Foyer!

If you can't make it and you don't find me near the #barebox demo at the assembly, shoot me a message, I am happy to meet up and chat about all things #embedded #linux, barebox and liberating boot!

[39c3] Workshop: Device Tree Handling and Linux booting with barebox

We'll walk through the barebox bootloader RISC-V webdemo at https://www.barebox.org/demo/ but many concepts apply equally well to ARM as well as booting Linux in general with other bootloaders as well. Optimally bring your own charged laptop with you.

16 years (minus 2 days) after the first #barebox release (v2009.12.0), we're happy to announce barebox v2025.12.0!

On top of a healthy amount of cleanup and bug fixes, 2 new features stand out:

📺 On Rockchip #RK3566 / #RK3568, MIPI-#DSI displays are now supported (pictured here running #bareDOOM).

🏭 For the barebox TLV factory data format, signatures can now be generated & verified. (See the upcoming FOSDEM talk: https://fosdem.org/2026/schedule/event/97DP7F-tamper-resistant_factory_data_from_the_bootloader/ for more info).

Release notes: https://github.com/barebox/barebox/releases/tag/v2025.12.0

@danct12 #barebox sounds like u-boot but better
I tried RK3568 MIPI DSI patches from @a3f for #barebox and I got a display out on my #pinetab2 :)
Ui, nice. #Barebox kann mit dem v2025.06.0 Release HS200 für eMMCs auf i.MX
In other news, I managed to learn even more about #uboot today. Still unsure if it was a good idea for society to go with U-Boot over sane alternatives, like #barebox ?
Why can't we all just agree to move on from #uboot to #barebox instead? My sanity would be secure and the world would be a better place ...
