Problem modifying NDK helloWorld example

David Aldrich92784

Hi

I have successfully built and run the NDK helloWorld example on a TCI6638 device using MCSDK 3.00.00.11 and NDK 2.22.2.16.

I need to adapt the example for our application and have therefore made some modifications, specifically in the QMSS initialisation functions.  Now when I run the modified example I see:

Starting the network

PASS successfully initialized

Ethernet subsystem successfully initialized

Ethernet eventId : 48 and vectId (Interrupt) : 7

Found an entry in PA response queue with swinfo0 = 0x11112222, expected 0x11111111

Add_MACAddress failed

Error: Unable to register the EMAC

Please can you suggest what might cause the error, or suggest a means of debugging it?

With best regards

David

    David,

    Do you get info showing QMSS and CPPI succesfully intialized in your log? We have some code change in the nimu driver code for the Add_MACAddress function (C:\ti\pdk_keystone2_1_00_00_11\packages\ti\transport\ndk\nimu\src\nimu_rth.c), can you try if this can resolve your issue?

    Regards, Eric

    Hi Eric

    Yes, QMSS and CPPI initialisation worked fine.  I already have the NIMU patch.  The problem remains.

    David,

    What did you change in QMSS intialization? Can you show the code?

    Regards, Eric

    Hi Eric

    Sorry for my delay in replying. Let me ignore your last question for now.  The error I get is:

    "Found an entry in PA response queue with swinfo0 = 0x11112222, expected 0x11111111"

    I have checked that the version of nimu_eth.c you attached is the same as I have.

    At line 2168 of nimu_eth.c there is:

    if (pHostDesc->softwareInfo0 != cmdReplyInfo.replyId)

    Now, the sw info value is set to 0x11112222 at line 2110:

    Cppi_setSoftwareInfo (Cppi_DescType_HOST, (Cppi_Desc *)pHostDesc, (uint8_t *)myswinfo);

    but the value of cmdReplyInfo.replyId is set to 0x11111111 at line 2079.

    So that 'if' statement (at line 2168) will fail and give the error that I see.

    This looks like a definite bug (at line 2168).

    Please will you investigate this urgently?

    BR

    David,

    No, the code is correct. I checked 2.1.2.6 nimu_eth.c and PA example code on how to add MAC address. The myswinfo is not related to pHostDesc->softwareInfo0. In your case, queue is messed up. Please send me the code how you changed QMSS/CPPI intialization in NDK, if possible.

    Hi Eric

    Thanks for your reply. It turned out that our QMSS initialisation code was initialising a region for the NDK descriptors with descriptor size 64, when 128 is required. So it was our initialisation code at fault.

    Thanks again

    David
