debugprobe, 80元人民币
再买一块pico, 刷上debug程序，仅要16元，当然用便宜的。
在mac上的vs code总是遇见问题
单独运行openocd时，也有问题，出现错误: CMSIS-DAP command CMD_DAP_SWJ_CLOCK failed
详细信息如下:
```
sudo ./build/src/openocd -f interface/cmsis-dap.cfg -f target/rp2040.cfg -s tcl

```
经过搜索，发现需要设置dap的速率,
直接修改rp2040.cfg, 添加速度。
adapter speed 5000，
都正常了。
正常的打印信息：
```
sudo ./build/src/openocd -c "gdb_port 50000" -c "tcl_port 50001" -c "telnet_port 50002" -c "adapter speed 5000" -f interface/cmsis-dap.cfg -f target/rp2040.cfg -s tcl
