Hi misc@, I managed to brick my PC-Engines APU2 with a (completed with zero) seabios image. The bios upgrade went fine but now the serial port outputs nothing and I cannot enter BIOS (coreboot) settings anymore. There is a apu2 spi1a device that has a way to boot the machine without a working bios flashed to the rom but I cannot find it anywhere. If you have one to spare I'm interested. Cheers,
