Part Number: TDA2PXEVM

Hi,

I wrote a simple linux gpio interrupt driver.

I want to test it on tda2x cpu board.

I have tda2x cpu board attached with vision board.

Do I have to detach the vision board to use the gpio pin? or I can use gpio pin with connected vision board.

Which gpio pin I can use to connecr a button to it and generate a interrupt using that button.

Thanks and Regards,

Akshay

Hi Akshay,

GPIO CSL driver is already present in PDK: PROCESSOR_SDK_VISION_03_07_00_00\ti_components\drivers\pdk_01_10_03_07\packages\ti\csl\src\ip\gpio.

There are multiple GPIO pins present on the board.

You can choose to use any pin as per your requirements.

Hi,

You don't need to remove the Vision daughter card.

As I mentioned previously you can use any pin that is not used by the use case you are running.
