Hi,

I have modified the enet-lwip code to ping and light the led when packet is received. I am able to ping to the board but not able to light the led on the board.

Can you please help.

    Hello Amit,

    I am trying to use the on board LED(PQ7)  itself.This is the DKTM4C129. Basically,I am trying to write code in which when pinged by the PC,the LED lights up.

    Regards,

    Anna

    Hello Anna,

    Is the Jumper J36 (between pins 5 and 6) mounted?

    Secondly, can you take a register dump of GPIO Port Q registers from offset 0x400-0x43C and 0x500-0x53C and send it across?

    Also when you try to light the LED s there sufficient delay between OFF-> ON -> OFF so that it is visible to the human eye?

    Regards

    Hello Amit,

    Thank you so much. I have managed to light it. Is there code to see if we can ping data from TIVA to PC via ethernet ?
