66AK2E05: Add mac address issue in PA emac with twist of bare metal (ARM)

Hannan Khan

Part Number: 66AK2E05

Hi !!

i have been working to reproduce the PA_emac example on ARM bare metal i am able to successfully transmit packet frm my k2e to the PC. Now i want to receive packets as well for which i need to setup the PASS LLD.

unfortunately i got stuck in the "Add_MACAddress" function where i receive a timeout which i know is because of the fact that the PA is not responding. I have checked my queues and descriptors etc which are an exact match of the one used in the sys bios PA_emac example but unfortunately i cant get any response.

below is the exact area where i am stuck

   Qmss_queuePush (gPaTxQHnd[cmdDest],
                    pHostDesc,
                    pHostDesc->buffLen,
                    SIZE_HOST_DESC,
                    Qmss_Location_TAIL
                   );

    for (j = 0; j < 100; j++)
    {
        CycleDelay (1000);

         if (Qmss_getQueueEntryCount (gPaCfgCmdRespQHnd) > 0) <-----this command fails

any help would be appreciated !!

Hi Hannan,

I've forwarded this to the QMSS experts. Their feedback should be posted here.

okay so i figured out that the problem was "Cppi_rxChannelOpen" function where i wasnt able to open all 91 channels which was in turn due to free function (malloc-free) prematurely being called !!

Hello!

May I ask you to clarify whether you found the trouble in your handmade code or that was related to delivered by TI?

Thanks

Thanks. We face similar trouble in SYS/BIOS project and I hoped to get some insight. Nevertheless, thanks.

you could probably check the malloc allocation which was my issue here which would mess up memory allocation in qmssLObj.
hope it helps
