How do I map Android GPIO to actual i.MX6 hardware pins

mikemandeville — Thu, 17 Jul 2014 21:58:52 GMT

I am putting together a rapid prototype system that is running Android on a Freescale iMX6 processor. I am trying to get the iMX6 to toggle a couple of GPIO pins, but I cannot figure out how to translate Android’s GPIO numbering to the iMX6 GPIO numbering. Android has class folders for GPIO175 and GPIO176, plus ones call GPIOCHIP128, GPIOCHIP160, etc but don’t know which GPIOs these would be on the iMX6.

Hi Mike

Numbering is the same as in Linux, for example

Request the pin to be used as GPIO:

#define LED_GPIO 6*32+7 */(GPIO7_7)

For Android link below shows usage
