R32.3.1 how to create the gpio mapping for GPIO3_PS.3

You explained GPIO3_PBB.0 but I can not make the translation of GPIO_PS.3 to a gpio.

Hi,
GPIO_PS.3 is gpio 259.

your documentation fails to point out the the GPIO_PS.3 that a second offset of “3” is needed. Offset is defined by MAIN or AON and the second offset is defined by the .3

Hi,
Please check

Please let us know if you would like to set other pins as gpio pins. We can suggest next.
