CH579M does not print full info (?)

Attempting to rerun the tool again give me Error: Input/Output Error instead.

Any Idea why?

Sorry for the inconvenience. The config register info is not filled yet for the CH57x family(requires some USB suffering and matching against the register map document). I do not have a CH579 board for now.🥲

[Nexxkinn]

Bummer 🤪

Please let me know if you're adding support for CH57x family :+1:

Here's the store I bought from, for reference.

@Nexxkinn I've just added support for CH579. Could you have a try?

@Nexxkinn Thanks. EEPROM(Data flash) erase/write/dump should also work.

@Nexxkinn Thanks. EEPROM(Data flash) erase/write/dump should also work.

Dumping and writing the eeprom has been confirmed to work on my device too.

Closing the issue, as the tool works generally fine for now.
