TMDSCNCD263: Pinmapping from TMDSCNCD263 to TMDSHSECDOCK (180 pin)

Part Number: TMDSCNCD263

Hi,

I am trying to map pins from the evaluation board to the docking station by referring the schematic provided at TMDSCNCD263 Evaluation board ,https://www.ti.com/lit/zip/sprcak1 (revision e2).

The doc says user led is on gpio_20 but I got it working on gpio_22, am I referring to the correct set of documents?

Also tried configuring GPIO51(ball D1) which as per schematic is available on pin 57 of the dock and GPIO13 (ball c10) available at pin 67 of the dock but could not observe any voltage changes on the pins at the dock after toggling them.

thanks

    It is document mistake because USER_LED0 connected to A8 of controller

    And A8 is gpio_22 not gpio_20

    I don't know why its gets failed, can you please let me know exactly which board you are using?
