CCS/TMS320F28379D: Peripheral problem

Tool/software: Code Composer Studio

Hi, I have a problem with the TMS320F28379D controlCARD.
I'm loading a program in the card without a problem and go into the debugger.
The program must turn on/off the LEDs connected at the GPIO´s 31-34 and increase a counter, It´s based on the blinky_cpu1 example project. The program runs and increases the counter (saw in the debugger) but the GPIO'S change in nothing, the registers don't change in the debugger and neither the physical output. I infer that can be something wrong in the peripheral. Can anyone help me? and How can I test if there is something wrong with my card?

Hi Luis,

In such cases, you will first have to check the relation between the GPIO number and (physical) pin number on the docking station you are using. Both are different and you need to see the pin-out for this. You can find it in {install_dir}\C2000Ware_1_00_XX_00\boards\controlCARDs\TMDSCNCD28379D\R1_3\TMDSCNCD28377D_180cCARD_pinout_R1_3.pdf

Which physical pins are you connecting your LEDs to on board?

Also, it would be easier for us to understand the problem, if you send a snapshot of your code. We can see if the configuration is being done correctly and you are accessing the right bit-fields/APIs.

Hi Ritvik,

These physical pins are the related to the Led2 and Led3, which are not working. Before, I worked fine with them, but now I don't have any output.

Luis,
Then I would like to have a look at your code to see what might have gone wrong. It would be great if you can insert your code here related to the above problem.
