EVMK2EX: EVMK2EX

Hi,

We are working on the K2E board NetCP Application with yocto version krogoth 2.1 and kernel version 4.4.32.

Here I am facing an issue in transferring packets using ethernet port0 or eth0, I am using SendPacket() and ReceivePacket() function for sending and receiving packets through NetCP application, If I am keeping the SendPacket() alone, then only I am able to transfer the packets, if I am keeping the SendPacket() and ReceivePacket() function together them I am not able to transfer the packets through NetCP port0.

If in Qmss_queuePush (gPaTxQHnd[1], pCppiDesc, dataBufferSize, SIZE_HOST_DESC, Qmss_Location_TAIL) call in SendPacket(), I keep gPaTxQHand[1], and select port1, the send and receive is working properly and if I, keep gPaTxQHand[0] and select port0 then I am not able to send and receive the packet.

    Hi Saurabh,

    Sorry for delayed response,

    You have been using K2E RTOS SDK, whether you are using ARM or DSP example projectas reference? 

    I have analysed the code of QMSS. 

    saurabh prajapati said:
    Qmss_queuePush (gPaTxQHnd

    Qmss_queuePush (gPaTxQHnd[nssGblCfgParams.layout.qPaTxCmdIndex]

Here, "qPaTxCmdIndex" corresponds to Index to the PASS Tx command queue for Egress Packets

    It doesnot point to Port number.

    CSL_CPSW_enablePort0()

    can be used to initilaize the Port 0, if it was not initialized properly.

    Thanks,
