    Hi,

    Can you explain what exactly you wanted to do? Not sure why you want to invoke a middleware (vision_apps) function in PDK example.

    Regards

    Hi    : Sivaraj R

            i       run  my   cnn   on   c66  ,  i     have   to   move  data between   DDR  and  L2RAM  ,     i  find   appUdmaCopy2D   in   vision_apps\utils\udma\src\app_udma_test      

           so   can   i   use   appUdmaCopy2D     to     move  data between   DDR  and  L2RAM ?

           i    find     appUdmaCopy2D    dest_pitch==src_pitch,       appUdmaFill2D    dest_pitch>src_pitch    

           so    if     dest_pitch<src_pitch        what   func   should     i  call ?

    thanks

    The UDMA driver supports all combination of configuration. The vision_apps DMA utils is written on top of UDMA driver to support specific usescases like memcpy and memfill. If more advance features are required, then the user can modify this utils as per their need.
