E77-400M22S, OpError 0x20

[davefes]

Has anybody got any experience with Ebyte E77-400M22S?

I seem to be able to get the Micropython build:
build-NUCLEO_WL55, with some modifications to
mpconfigboard.h to run to the point where I get
this error:

RuntimeError: Internal radio Status (2, 1) OpError 0x20 sx126x.py micropython/lora

My guess is that some internal oscillator is not being configured properly,
but the manufacturer could not help.

That NUCLEO_WL55 has micropython-lora baked-in.

Appreciate any suggestions, thanks.
