    What is the link before the dupLink and how many channels are active ? The assert indicates the number of input buffers to dupLink has exceeded 320 frames

    What is the link before the dupLink

    =>merge link after DEI/DEIH


     how many channels are active ?

    => 8 ch


    exceeded 320 frames

    ==> how to know this number?

    hello Super-Badri

    thanks for your reply...


    The assert indicates the number of input buffers to dupLink has exceeded 320 frames

    ==> did you mean a lot of frames are feed to dupLink ??

    If you have only 16 channels of DEI then it is unlikely that dupLink buffers have exceeded. It is only possible if DEI had 20 output buffers per channel which is not possible.It looks like you are seeing simultaneous decode errors and M3 exception. This indicates DDR on your board is not stable. Ensure you have DDR s/w leveling for your board and check your board complies with DDR layout guidelines. Also do DDR stress test on your board for 1 day duration to confirm no failures.

    hi Badri,

    thanks for you response.

    By following

    I try mtest under uboot and got below,

    hi Badri,

    I have one more question~~.

    I try following  and it seems stuck.. does it mean any thing??

    I try to find out the uboot location in the DDR but can't find, do you know where is it ?

    Hit any key to stop autoboot: 0

    By checking,

    The DDR range of Uboot could be found in u-boot.map which will be generated after compiling...

    after avoiding that...I can keep going...

    uboot# mtest 0x80000000 0x806F5000 0xaa55aa55 1
    Pattern AA55AA55 Writing... Reading...Tested 1 iteration(s) with 0 errors.

    hello Badri,

        I have followed the link below to check if something wrong in the board

           http://processors.wiki.ti.com/index.php/DM816x_C6A816x_AM389x_DDR3_Init

        and try the tool mentioned in 

        http://e2e.ti.com/support/arm/sitara_arm/f/791/t/224435.aspx

      And the DDR test result is successful.

    By another platform, they provide their diagnosis tool for the DDR and we can find out the problem which isn't detected by uboot, or even memtester...Does TI have this tool ??

    7725.DDRStressTest.zip

    Attached is DDR stress test which does much more stressful test of DDR compared to simple memtest. You need CCS+JTAG to run it.

    hi badri,

    thanks for your reply.

    I have try the CCSv4 but I can't open the project inside. Is there any wrong ??

    It is a CCSv5 eclipse CDT project.
