We are currently working on a custom board, with a custom Yocto on a Colibri iMX6 SOM, and we experienced some problems with GPIO5_IO02 (pin 86).
I tested some GPIOs, and all of them work except GPIO5_IO2. In the .dtsi, the pad is configured like this :
MX6QDL_PAD_EIM_A25__GPIO5_IO02 PAD_CTRL_HYS_PU and the other reference to this pin is commented.
I exported the GPIO, set the direction out, and set the value to 1. When I do
cat /sys/class/gpio/gpio130/value the value is still 0! On voltmeter the value is 0V and does not change at all.
Do we miss something?
