JTAG-DP(JTAG Debug Port)是STM32等微控制器上用于调试和编程的一个接口。它提供了完整的JTAG功能,包括数据访问、断点设置、单步执行等。然而,在某些情况下,为了节省引脚资源或避免与其他功能冲突,可能需要禁用JTAG-DP。 在STM32中,可以通过配置AFIO复用功能寄存器MAPR的SWJ_CFG位来禁用JTAG-DP。具体地,当将SWJ_...

this is as expected as I have disabled the SW-DP interface. Now the strange part; I can't reset it anyway. When forcing the reset input low, the CPU only seems to lock up. There is no way to restart the STM again, though it started after programming... ...
