Hi:Brijesh

we use psdk_rtos_auto_j7_06_01_01_12，we've managed to run six CNN on the C66，

but two of CNN's final output is not correct, after checking, we found that it was caused by inconsistency between source data and result data after using appudmacopy2d to copy data.

we  use appudmacopy2d to copy data from DDR to L2RAM at each layer of CNN,

Kenel function reads data from l2ram and stores the output result in l2ram, and then uses appudmacopy2d to copy the output result from l2ram to DDR.

DDR_input  appUdmaCopy2D   L2RAM_input  kenel_fuction  L2RAM_output appUdmaCopy2D   DDR_output  CacheP_wb（DDR_output）

we compare MD5 of source data and target data of each appudmacopy2d, DDR input MD5 and l2ram input MD5, l2ram output MD5 and DDR output MD5.

we find that the l2ram output MD5 and DDR output MD5 of some layers are inconsistent

 how   can   we    solve   it ?

Thanks!
