That’s perfect - that was going to be my next step. Now I’ve added it, it boots all by itself - thanks!
I actually have grubaa64.efi . Not sure what went wrong there…

It is apparently configured to run at 2GHz - I had to do this as I wouldn’t have enough jumpers to boot from the SD card! When building OpenJDK multi-threaded the CPU was running at about 42 degrees Celsius - the fan is doing its job.

The 1.3s have fans already installed on the heatsink. They also have an open pci-e slot, and there is a JTAG header installed, but offset from the PCI-e slot, so you don’t need to remove it.
