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_...

The easiest is to connect the Bus Pirate 3.3volt power supply pin to the to the 3.3volt pin of the JTAG header on the CPLD board (but this might be dangerous to the voltage regulator on the CPLD board) Alternately, connect the Bus Pirate 5volt power supply pin to the V+ pin of ...
器件型号:DP83867IR 你(们)好 我的客户正在使用 DP83867、目前 JTAG CLK、TMS 和 TDI 引脚通过电阻下拉、TDO 悬空。 但是、他们的测试工程师要求他们上 TMS、TDI 和 TDO 来帮助他运行 BSCAN。 如果我们这样做、是否会对正常运行产生任何有害的副作用?
