STEVAL-IHM039V1的JTAG编程无法通过OpenOCD连接到主板

你好！我正在使用STEVAL-IHM039V1和STEVAL-IHM027V1构建电机控制器。我收到了这些主板，为我的设置配置了固件（FOC SDK 3.4）和硬件设置（三分频pmsm w /霍尔传感器），并使用JTAG连接器，ARM-USB-tiNY-H编程器/调试器刷新代码和gdb / OpenOCD。 LCD接口工作等。


但是，一旦我刷了代码，我就再也无法通过OpenOCD连接到主板了。它说它无法检测到电路板。但是，如果我在连接时按住重置按钮，我可以连接到它并重新刷新它。这让我觉得固件中的某些引脚设置可能不正确，这会使JTAG不起作用。有任何想法吗？

以下是尝试连接的OpenOCD的输出：

Hello! I'm building a motor controller using the STEVAL-IHM039V1 and the STEVAL-IHM027V1. I received these boards, configured the firmware (FOC SDK 3.4) and hardware settings for my setup (three-shunt pmsm w/ hall sensors), and flashed the code using the JTAG connector, an ARM-USB-TINY-H programmer/debugger, and gdb/OpenOCD. The LCD interface works and so on.


However, once I flashed the code, I can no longer connect to the board through OpenOCD. It says that it can't detect the board. However, I can connect to it and reflash it if I hold down the reset button while connecting. This makes me think that some pin setting might be incorrect in the firmware that somehow makes the JTAG not work. Any ideas?

Here is the output of OpenOCD trying to connect:
