大家好!!最近遇到个问题,TLV320AIC3204IRHBR,8核数字信号处理器,使用时不知道是哪里出现了问题:

在操作时,连接处理器的JTAG接口后,这个处理器里面的8核没有连接,
如果在连接JTAG接口之后使用JTAG的重置功能，JTAG连接就被关闭了.

When DSP JTAG is connected, some of the cores inside the DSP are not connected -> 8 cores inside the DSP
If you perform DSP RESET using JTAG after connecting the DSP JTAG, the JTAG connection will be turned off.
After replacing with a DSP purchased from another place, the above phenomenon does not occur and it operates normally.

在DSP本身都是正常的情况下,为什么会出现上述问题啊?我该怎么找出问题出现在哪里呢?
