Mark McBrideCaptured some detailed notes on my latest hardware creation for remote server access. I mean, who doesn't need to cold boot their home servers from the other side of the planet?

This has been a fun mini-project. I'll improve the cabling, but the solution is complete. A PoE-powered ESP32 device that monitors the UART consoles of a #RaspberryPi 5 and an #odroid H4 Ultra. It also controls two relays (power switches) to the same two devices. Even cooler, I can use ttyd/xterm.js as a front-end on a socat TCP stream, which means I can access the consoles via the web. It’s like a DIY BMC. The two computers are running #alpinelinux and #FreeBSD. Both work without issue.
With a few cheap parts, you can control the power state of an ODROID H4 entirely remotely. As a bonus, you'll be able to say “optocoupler" at parties and sound cool.

Thomas WiebeDiese Woche geht es bei @ajfriesen und mir um eine ODROID-H2 Proxmox Farm und Proxmox auf einem M920Q mit Intel AMT. Beides lief, sagen wir mal, rund. 🙃
Dazu noch TLS und Stromsparen im Home Lab.

DasharoIf you're working with #ODROID H4+ and want complete control over your firmware stack, this demo shows exactly what Dasharo (coreboot+UEFI) brings to the table. It walks through hardware bring-up, key #firmware features, and the developer workflow needed to turn this small board into a transparent and maintainable platform. The presentation highlights how open-source firmware improves debuggability, long-term sustainability, and trustworthiness without locking you into proprietary boot paths.

T_XSo, finally got the Linux kernel updated on a trusty, old #Odroid U3. Wrote a script now to convert the vmlinuz and initrd provided by Debian to the formats expected by its specific u-boot, with a lot of error checking. Then, still things didn't boot - kernel got so large it'd overlap into the fixed memory position of the initrd. Relatively simple fix, but took some time, too, to get the UART set up again.
Courtney RosenthalI stopped using Raspberry Pi's ever since the RPi Foundation went cray-cray. The last one in service was my Home Assistant controller. It's started hanging, and rather than troubleshoot (who the hell knows where my mini-HDMI cable is), I think it's time to migrate.
Ordered an Odroid M1S today.

Looking forward to dumping the last of my RPI's.
