ac78013fdla只能下载一次，后再也连不上了

KEIL5.25，用J-LINK调试程序，空芯片时，电流是5mA，第一次按调试时能进入调试，但无法到main的第一句。
后面，电流变成了11mA，再下载或擦除变成了NO CORTEX-M SW DEVICE. 到flash设置，与原来没有啥区别。
下面是信息，这不知是啥问题？？

jlink的驱动不对，需要6.90及以上版本

猜测应该是下载进去的程序使用的时钟配置有问题，导致实际系统时钟超过最大时钟被锁了，可以找原厂确认一下

换了JLINK的版本，刚装时好的。后来装了其它的驱动和软件，现在能连和下载，但是调试无法停止。晕倒。

6.90及以上版本，你这直接拉到最新了，可能是最新的不太稳定吧，

我用的是6.90a，建议可以试试，目前没有遇到什么问题
