hi,everyone.
i met a confused problem about dm6446 image data copying，please help me.
my codec algorithm about moving object detecting is xdais compatible,
i apply memory(such as 5M) from the CE framework by filling the structure memTab that used for building the ring structure for storing the images.
the algorithm on the dsp side get the source image data from arm via mem sharing and save it in the ring structure mentioned above.
and I use memcpy function for saving the image data in the ring structure.
that is to say,i use memcpy function for copying the image data from memory which allocated by Memory_contigAlloc to memory(ring structure) that memTab offers.
but something wrong happened.
next two pic shows the result. it seems tht the data has offset。
the right pic
the wrong pic
the wrong pic is the result of the ring structure data。
is memcpy function wrong????
Please help me.
