@polluks:
I tried setting that, but I am a bit unsure where that debug logging is supposed to end up. Is it on the serial port?
Took a look at the morphos ramdebug output with logtool and got some output when onlineing the interface which doesn't seem say very much apart that a read goes wrong:

The address it is attempting the read from changes for each run. This was with the a debug version of the device, but it doesn't seem to help with any symbols or anything.. can't say that I know much about using these kind of tools unfortunately.
Also tried with the non debug version of the device and got sortof the same thing, but an illegal write instead. It seems to be 100% reproducible and debug device = read fail, normal device = write fail.
Normal device output:
