Hello sir,

    I am confusing after seeing the memory allocation in ld file...Please clear these things

  In the  bf 561b.ld  file you are giving the B_MEM_* are for  Core A memory region . 

  Although in the bf 561a.ld file  B_MEM_* are for  Core B  Memory region.

  Then what is the memory distribution in the bf 561m.ld file? Please clear these things.

  -Regards

   Pranay

              I think there should be not effect of naming convention. Is any limitation and naming conventoin for use of the

     external memory SDRAM for Core A and Core B. For using single core I am able to write and excess the data from SDRAM but when I am using the Dual core I am not able to read write the video data from the SDRAM, in Standalone application.Please reply.
