Mapping gpiochip to HPS_LTC_GPIO

Unread post by artfakt »

I'm trying to figure out how to access the single 3.3v gpio on the LTC connector named HPS_LTC_GPIO in the schematic via bash.

under /sys/class/gpio I have only gpiochip1963 gpiochip1990 and gpiochip2019

this doc doesn't have the same gpiochip numbers https://github.com/intel-iot-devkit/ter ... E_gpio.txt

I was able to use i2cdetect on the nearby pins with success but not the gpio.
I want to be able to set the direction of this pin and the value.
