我是 OpenOCD 的初学者，我正在尝试使用 ST-Link v2 调试器或 OLIMEX 在菊花链中闪存 3 个 STM32 目标，如下所示，使用 OpenOCD。
如果只连接一个目标，我使用的代码就可以工作。但是如果我将它连接到多个目标，OpenOCD 会抛出一个错误，指出 init 失败。
"C:\Program Files\GNU ARM Eclipse\OpenOCD\0.10.0-201601101000-dev\bin\openocd" -f "C:\Program Files\GNU ARM Eclipse\OpenOCD\0.10.0-201601101000-dev\scripts\interface\stlink-v2.cfg" -f "C:\Program Files\GNU ARM Eclipse\OpenOCD\0.10.0-201601101000-dev\scripts\target\stm32f3x.cfg" -c init -c targets -c "halt" -c "flash erase_sector 0 0 127" -c "reset halt" -c "flash write_image C:/Users/Buero-1/Desktop/openOCD/init.hex" -c "verify_image C:/Users/Buero-1/Desktop/openOCD/init.hex" -c "reset run" -c shutdown
执行此代码时我得到的成功结果如下所示。

但如前所述，如果我在 JTAG 链中连接多个目标，则进程在init处停止并且程序结束。
配置文件是 target/stm32f3x.cfg、interface/ftdi/olimex-arm-usb-ocd-h.cfg 和 interface/stlink-v2.cfg。
如果我的问题非常基本，请原谅。如果向我提供有关如何处理我的问题的最新信息，那将非常有帮助。
谢谢你。
