How to define a pin as GPIO in the kernel Device Tree in ixm8mm for Android OS
i tried doing same as yocto and build there its error or it doesnot build completely after the all the device tree file it leaves the directory and doesnot continue.
i have attached screenshot below.
Can u kindly provide me documents related to Android OS . version 10
I am able to create virtual GPIO pins
$ echo 117 > /sys/class/gpio/export
The gpio creates gpio117
later i ON and OFF the imx8mm it disappears
How it set in device tree and stay permanent .
I want Document related to Android OS only
i tried even changing in imx8mm-evk.dts
&iomuxc {
pinctrl-0 = <&pinctrl_hog_1>;
imx8mm-evk {
pinctrl_hog_1: hoggrp-1 {
fsl,pins = <
MX8MM_IOMUXC_GPIO1_IO08_GPIO1_IO8 0x19
MX8MM_IOMUXC_SAI5_RXD3_GPIO3_IO24 0x41
>;
};
...
};
Its not building
