执行：
sudo ./openocd -f wch-riscv.cfg -c init -c halt -c "flash erase_sector wch_riscv 0 last " -c exit
报错：
./openocd: symbol lookup error: ./openocd: undefined symbol: jaylink_device_get_usb_bus_ports
请问这是什么原因？怎么处理？
用的jlink?
是WCH-Link，

以前版本的MounRiver_Studio_Community_Linux中可以正常下载的，且windows下也正常下载。
您好，您可以用MounRiver_Studio_Community_Linux先下载一下，然后在MounRiver_Studio_Community_Linux目录下toolchain\OpenOCD\bin 使用相关指令试一下。
以前正常的命令行显示：

您好，请执行下 ldd /home/abc/MRS_Community/toolchain/OpenOCD/bin/openocd，看下是否能找到所有的依赖库。有缺失的话搜索一下，添加到默认路径或者单独设置都可以
