執(zhí)行：
sudo ./openocd -f wch-riscv.cfg -c init -c halt -c "flash erase_sector wch_riscv 0 last " -c exit
報錯：
./openocd: symbol lookup error: ./openocd: undefined symbol: jaylink_device_get_usb_bus_ports
請問這是什么原因？怎么處理？
用的jlink?
是WCH-Link，

以前版本的MounRiver_Studio_Community_Linux中可以正常下載的，且windows下也正常下載。
您好，您可以用MounRiver_Studio_Community_Linux先下載一下，然后在MounRiver_Studio_Community_Linux目錄下toolchain\OpenOCD\bin 使用相關指令試一下。
以前正常的命令行顯示：

您好，請執(zhí)行下? ?ldd? ?/home/abc/MRS_Community/toolchain/OpenOCD/bin/openocd，看下是否能找到所有的依賴庫。有缺失的話搜索一下，添加到默認路徑或者單獨設置都可以
