Mode switching

  • 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.

Mode CMSIS-DAP-dat

  • 1,确保 WCHlink 工作在 ARM 模式,CON 指示灯亮是 ARM 模式,否则通过短路 TXD-GND 来切换。
  • 2,接下来使用和普通 MSIS-DAP(DAPLink)使用完全一样,在 keil 设置中尤其注意 Reset 设置为 SYSRESETREQ。
