Stand Alone Video Decoder
We are using Analog devices MPEG4 decoder library in our application which
is built on the BF-561 processor & tools used is vdsp 4.5 version.

Inside the mpeg4 library the MDMA routines are used for memory copying, the
processor always waits in this loop "dmawaitrefiny0" for MDMA to
complete,

But control never comes out of this loop.

 

The problem is, the variable MemDMADoneFlag_L3 should be declared in L3 instead
of L1.
