This tool is deprecated by wlink, mode switch already supported by wlink, please use wlink instead.

'wchlinke-mode-switch' is a command-line tool to switch WCH-LinkE (with latest firmware) modes between DAP and RV from host, and tested with WCH official WCH-LinkE and MuseLab nano WCH-LinkE adapter.

WCH-LinkE support online debugging and downloading of WCH RISC-V MCU (2 wires RVSWD / ch32v003 1 wire SDI interface), and also support online debugging and downloading of ARM MCU with SWD/JTAG interface. It also have a serial port.

The dual modes (DAP / RV) of WCH-LinkE can be switched by some official close source utilities, such as MounRiver Studio, WCHISPTool, etc. And also can be switched by onboard 'ModeS' button (and why it have a case ?!)

For more infomation about WCH-LinkE, please refer to official manual.

If this utility doesn't work as expected, please refer to official manual to update the firmware to latest version.
