Today I reconfigured my APU1D to boot via net (PXE instead of the SD card). Since then the APU doesn't boot at all, even the serial console stays blank/empty.
When turning the APU on all NICs flash once (orange led), all green leds (d5, d6, d7, d10, d11) turn on and after 1-2 seconds d5 and d6 turn off again. Pressing s1 button has no effect. Console stays blank, NIC doesn't request an IP (though the orange led is on), APU doesn't boot from disk/sd card).
Any ideas what's going wrong?
