Compiler/PROCESSOR-SDK-DRA8X-TDA4X: c7x l2RAM baseaddress

Hi Shuai,

Why can't we directly use system address of the L2RAM? I believe this should be possible to directly use system address..

Hi  ：Brijesh

1. i   close   ENABLE_IPC      as    i   test    use   JTAG  on   single  core    C66  or   C7X.

      2. in      vision_apps\apps\basic_demos\app_tirtos\tirtos_linux\c7x_1\main     func  appMain     i   call       appUdmaTest();  after   appInit();  

          in    c66   the  same.

     3. i   load   psdk_rtos_auto_j7_06_01_01_12/vision_apps/out/J7/C71/SYSBIOS/debug/vx_app_tirtos_linux_c7x_1.out     to  c7x  core  by  JTAG   and  run.

       by   this   step    i  have      appUdmaTest2DCopy   succeed  run   on     C66  and  c7x  ,   but   in   appUdmaTest2DCopy    copy   data   from   DDR  to  DDR  by   UDMA.    so  i   try   to   copy   data  from   ddr   to   L2RAM  .

i    change    code       

dest_buf = appMemAlloc(APP_MEM_HEAP_L2, size, UDMA_CACHELINE_ALIGNMENT);

prms_2d.dest_addr = appMemGetVirt2PhyBufPtr((uint64_t)dest_buf, APP_MEM_HEAP_L2);

but   it   failed   both   on  c66  and  c7x   core     ,appUdmaCopy2D   return  -1   .

i  found   it  is  appMemGetVirt2PhyBufPtr   do  noting .  so  i   use  CSL_C66SS1_C66_SDMA_L2SRAM_0_BASE    and CSL_C66SS0_C66_SDMA_L2SRAM_0_BASE   done    appMemGetVirt2PhyBufPtr     now    copy   data   from  DDR  to  L2ram   is  ok .

    if ((phyAddr >= C66_COREPAC_0_L2_BASE) &&
        (phyAddr < (C66_COREPAC_0_L2_BASE + C66_COREPAC_0_L2_SIZE)))
    {
        phyAddr -= C66_COREPAC_0_L2_BASE;
        phyAddr += C66SS0_C66_SDMA_L2SRAM_0_BASE;
    }

i     try  to   do  the  same   on c7x   so    i  find   baseaddress   of  C7X

Thanks

Hi :Brijesh

      dest_buf = appMemAlloc(APP_MEM_HEAP_L2, size, UDMA_CACHELINE_ALIGNMENT);

        prms_2d.dest_addr = appMemGetVirt2PhyBufPtr((uint64_t)dest_buf, APP_MEM_HEAP_L2);

        here    dest_buf =  0x64800000;

        prms_2d.dest_addr =1686110208;

Thanks!

Shuai
