CH32V203C8T6 working #30

Open arsonoff opened 1 year ago

arsonoff commented 1 year ago

Chip CH32V203C8T6 (board nanoCH32V203 or CH32V203EVT):

$  python3 -m ch55xtool -v -p
Chip ID: 31 is not known = not supported
Welcome to report this issue with a screen shot from the official CH5xx tool.

31 - hexadecimal value, is not clear at once.

Added to the typeall.wcfg:

[CH32V203C8T6]
McuType=9
MaxFlashSize=65536
MaxEepromSize=0
IsNetworkDown=0
IsUsbDown=1
IsSerialDown=1
chipid=49
eepromStartAddr=0
Introduction = ""

flash/verify_flash/print configuration - working !

McuType has to correspond to bMCULine from WCHISPTool?

Why CH32V307 in typeall.wcfg has only one point? According to WCHISPTool CH32V307 has three different chipid:

    CH32V307WCU6 - 115
    CH32V307VCT6 - 112
    CH32V307RCT6 - 113

There are a couple of nuances: 1) flash-image has to be multiple 32 bytes, otherwise add with bytes of x0. 2) MCU should not be in the Protect mode. Such mode is activated by official tools (WCHISPTool (Win), WCHISPTool_CMD (linux))
