Note
Keils 识别不到的需要更新 Keil 版本至 5.25 以上
Mode
| 模式 | 指示灯 | IDE | 支持芯片 |
|---|---|---|---|
| RISC-V | 空闲时蓝灯常灭 | MounRiver Studio | 本公司支持两线调试接口的 RISC-V 核芯片 |
| ARM | 空闲时蓝灯常亮 | Keil | 支持 SWD 协议的 ARM 核芯片 |
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。
