The development board I use for flashing etc. has got a serial port connector and even a USB to serial converter so you can just plug in USB to your laptop - I did not get any console output, though. https://www.waveshare.com/wiki/Compute_Module_PoE_Board#Serial_port I did get console output via HDMI, but my Apple keyboard seems not to work when plugged in to USB so I could not really examine what is wrong or boot into kernel.old - only diagonistic I can provide: The new kernel prints the "No MAC address found" message, then panics. I'm reflashing the module now ... =46rom reading your source code, what are you really trying to achieve? More diagnostic messages are a good thing, but from where are you trying to read that MAC address? As far as I understand for the Pi you are supposed to use the RPi foundation OUI B8:27:EB plus the lower three octets of the Pi's serial number - regardless of the Ethernet adapter plugged in. All Pis running Linux do this. Kind regards, Patrick=
