Hi,
My project 用到CMEM，linux下的DTS reserved-memory，都是default的，DDR3 0xa0000000~, OCMC-RAM3 0x40500000~0x40600000;
共享内存在ARM与DSP1之间put/get, 现在是CMEM用DDR3上的，程序能长时间运行；但是在OCMC-RAM3上，加载到load-firmware时有unload时的错误，load好像正常。
后面app_host, 就报如下错误， 不知道是不是remoteproc，mmu什么定义有问题，是不是跟OCMC-RAM3 0x40500000~0x40600000区间冲突了？
DSP1/DSP2的mmu定义我没有修改，应该都是default的。
请问专家，这是什么问题导致的，如何修改？
谢谢！
