I have the first WCH-Link, the one based on CH549. I want to flash a CH32V003, which is currently not supported.

So I tried upgrading the WCH-Link firmware, using the file WCH-LinkUtility/Firmware_Link/FIRMWARE_CH549.bin from the WCH Link Utility zip file with the J1 switch and wchisp. Now it is no longer showing up on USB. There are also the following files:

FIRMWARE_CH32V203.bin  FIRMWARE_CH549.bin      WCH-DAPLink_APP_IAP.bin   WCH-LinkE-APP-IAP.bin
FIRMWARE_CH32V208.bin  FIRMWARE_DAP_CH549.bin  WCH-Link_APP_IAP_ARM.bin  WCH-LinkW-APP-IAP.bin
FIRMWARE_CH32V305.bin  firmware_version.txt    WCH-Link_APP_IAP_RV.bin   wchlink.wcfg

Do you have any idea? Would I need to flash one of those *_APP_* files to another location?

EDIT: I flashed the WCH-Link_APP_IAP_RV.bin and now the programmer shows up as 1a86:8010 QinHeng Electronics WCH-Link again. :relieved:
