Tool/software:

Hello,

How can I set the ethernet link and activity lights to different GPIO other than PF0 and PF0?

Tivaware 2.2.0.295 with net_s2e example on EK-TM4C1294XL board.

Thanks,

Keith

    Hi,

      You can refer to to C:\ti\TivaWare_C_Series-2.2.0.295\examples\boards\ek-tm4c1294xl\drivers\pinout.c file. Look for the below snippet of code on Ethernet LED configuration.

      For example, by default it is using PF0 for EN0LED0. However, you can change this from PF0 to PK4. Refer to the datasheet. 

    //
    // PF0/PF4 are used for Ethernet LEDs.
    //
    if(bEthernet)
    {
    //
    // this app wants to configure for ethernet LED function.
    //
    MAP_GPIOPinConfigure(GPIO_PF0_EN0LED0);
    MAP_GPIOPinConfigure(GPIO_PF4_EN0LED1);

    MAP_GPIOPinTypeEthernetLED(GPIO_PORTF_BASE, GPIO_PIN_0 | GPIO_PIN_4);
    }
    else
    {
