After a bit of fiddling with serial connection and flashing all the stuff. It boots.
It does feel a bit strange that you can now have a 64-bit, 64MB computer that fits on a breadboard. That runs full Linux.
My first 64-bit system was a Aspen Alpine Alpha board, AT format. 275Mhz Alpha CPU and also 64MB of memory. That ran full Linux (a probably still do. It should still work)
Anyway, boot log from serial console for the Ox64 below:
