Some more information about the WCH chip config on the badge #110
Description
This commit
#109
added the command: wchisp config reset
This command is something deeply different then what you probably expect it to be. Its not a reset to default settings to remove animations you installed on the badge. Its changing deeper settings from the WCH chip. Its not solving #77
Could someone explain in combination with the badge hardware how its affecting things?
Here is the outcome:
The USB-C preproduction badge with the two additional buttons for games:
I was not able to flash this badge. The flash command always failed. But after i reset the config, i was able to flash the firmware. Sadly the badge have rows of broken LED's. Or maybe its now something WCH chip config related?
Here whole workflow from not be able to flash to verified flash from this preproduction board:
