Firmware for the Turing Pi 2 that boots a new image on trial and takes it back if the board does not come back right. Upstream stopped in February 2025.
Upstream promotes a new image the moment it boots, which proves the kernel started and nothing else. Here it boots on trial and is kept only if the board comes back right. It has said no once, on purpose, to a tampered image — in about 35 seconds.
Upstream power-cycles all four compute modules to update the management computer beside them. This fork leaves their rails alone, so patching the board that manages your cluster does not take the cluster down. Measured on a Turing Pi 2 v2.5; a v2.4 drives its node rails from the BMC itself, so there any BMC reboot power-cycles all four.
A board that can reflash four computers should not face the internet. One page inside the cluster drives them all, with every control a board has, and it holds no credential of its own.
Upstream's last release was v2.1.0, in February 2025, on a kernel that is not a longterm release and a Buildroot that is end of life. This fork tracks both, and has taken out six named faults — including the one that killed this board twice in a day.
What is a Turing Pi?A mini-ITX board carrying four compute modules — Raspberry Pi CM4, Turing RK1 or Nvidia Jetson — with their network switch, power, and a small management computer on the board itself. That computer, the BMC, is what this firmware runs on: it powers the modules, flashes them and hands you their consoles. Made by Turing Machines — turingpi.com →
