I have bought 2 APU2 the last Days. One works well, the other do not boot. When I power up the unit, only the right LED (view from Front) lights up.
is the hardware defective?
It looks like the BIOS is corrupted on the second board. If You have a spi1a dongle, You can check if this is a hardware defect or BIOS corruption.
If not, I have an idea how to recover the second platform (kind of experimental, thus would like You to test spi1a first).
