Also got a Bitburner XX (Avalon chips). Again, I assume bfg supports these things?
Bitburner still hasn't provided and docs, sample units, code, or even communicated.
I believe they emulate Avalon units with the mcu. So -S Ava:/path/to/bitburner may work
I might try adjusting the --Avalon-options to follow the bit burner formula.
And looking at cg's driver, btb is a sub driver
