关于SPI3初始化需要关闭JTAG-DP 问题来了 在线仿真时跑飞了

wgh1990

初始化SPI3或者重映射SPI1 需要做这么一步才能AFIO->MAPR|=0X02000000; 或AFIO->MAPR|=2<<24; 才能完成初始化正常使用 但是在线仿真就不行了 当运行到这里就会出现以下情况：

有没有什么办法可以跳过或者解决  虚心请教

正点原子

回复【楼主位】wgh1990:
---------------------------------
你这配置把JTAG关闭了，当然不能再仿真了...

正点原子

用SWD仿真。

用的就是SWD  没用JTAG  很纳闷了

我试过采用你解决mini板按键的做法 不过不行
