6678 srio keystone_srio



自己的板子,用的是论坛的keystone_srio程序,板子上有三片6678,运行srio初始化程序,有两片没有问题,另外一片初始化srio有时会成功,有时会报错,错误信息是trouble reading register controlregister_csr:(error -1202 @ 0x41) device core  is  hung.the debugger will attempt to force the device to a ready state to recover debug control.

而且进行ccs的cpu reset和system reset也没用

不知道为什么会这样,希望TI的工程师或者各路大侠能解答一下。

谢谢!
