TMSC6748 vpif module unable to read CxTLUMA



Hello,

I am trying to process video with DSP core on OMAP L138-Evm board. I obtained a sample code from LogicPD website as composite video test. The memory address for video is determined as 0xC1000000 and it is written into C0TLUMA. I am running the code on CCSv4.2 without errors or warnings but when i look from view->registers to C0TLUMA, it says unable to read. And when i check that memory address from view-> memory, all zeros.I checked for C0TCHROMA and bottom field registers too, at all it says unable to read. How can i write the video in that address? Please help.
