I recently got the apu2d4 and I wanted to update the firmware to the latest version before any OS installation. I downloaded v22.214.171.124 and then added to it to my Tinycore bootable disk. I then used “flashrom -w apu2_v126.96.36.199.rom -p internal:boardmismatch=force” to upgrade the firmware. Everything went fine here. After updating the firmware, I power cycled and rebooted the computer and all I see now is:
PC Engines apu2
Coreboot build 20190907
BIOS version v188.8.131.52
...and nothing happens after this. I don’t see the boot menu. All the three lights on the front panel are green and ON. Have I bricked the computer? What am I missing?
