使用脚本：
#!/usr/bin/env bash
SOURCE=/usr/share/openocd/
INTERFACE_CFG=${SOURCE}scripts/interface/cmsis-dap.cfg
TARGET_CFG=${SOURCE}scripts/target/stm32f1x.cfg
PWD=$(dirname "$(readlink -f "$0")")
echo "开始连接"
openocd -f ${INTERFACE_CFG} \
-f ${TARGET_CFG} \
-c "init" \
-c "halt" \
-c "stm32f1x unlock 0" \
-c "reset halt" \
-c "exit"
效果如下：
lizigarden@leeds-ThinkPad ~/p/S/HelloWorld> sudo ./unlock.sh
