When Tx is connected to GND, plug the WCH-Link into the USB interface to switch the mode and keep it in this mode the next time it is plugged into the USB interface.
Example:
When the current WCH-Link is idle, the blue light is always off, indicating that it is in RISC-V mode; after powering off, short-circuit Tx and GND and plug it into the USB interface, and the mode is switched to ARM. At this time, the blue light is always on when idle; Turn on Tx and GND, and it will still be in ARM mode the next time you plug in the USB interface.
