LAUNCHXL-F28379D: XBAR GPIO to GPIO

Jejomar Ildefonso
Genius 9290 points
Part Number: LAUNCHXL-F28379D

Hello, 

I am trying to connect 2 GPIOs in a LAUNCHXL-F28379D, 

GPIO8 Input of a clock signal (1khz). 

GPIO5 Output of the cock signal (It must drive a Mosfet driver) (Output XBAR3 agreed with the datasheet).

The configuration code is as follows: 

    EALLOW;
    //
    InputXbarRegs.INPUT1SELECT = 8; //OUTPUT3MUX16TO31CFG
    OutputXbarRegs.OUTPUT3MUX0TO15CFG.bit.MUX1 = 1;
    OutputXbarRegs.OUTPUT3MUXENABLE.bit.MUX1 = 1;
    OutputXbarRegs.OUTPUTLATCHENABLE.bit.OUTPUT3 = 0;
    OutputXbarRegs.OUTPUTINV.bit.OUTPUT3 = 0;
    //GPIO_SetupPinMux(5, 0, 6);
    GPIO_SetupPinMux(5, GPIO_MUX_CPU1, 1);
    GPIO_SetupPinOptions(5, GPIO_OUTPUT, GPIO_PUSHPULL);
    //
    EDIS;
 
Would appreciate your help as we can't get it to work and I couldn't find any related topic about this issue. Thanks in advance!

 
Kind regards, 

Jejomar
