Hello Everyone,
We are using Am437x based custom board. Kernel image is builded by SDK04.02. I changed my dts file to achieve particular functionalities. I can able to get that but i had a doubt regarding gpios which appearing under dmesg though all working well i also want to bring all gpios to make my image perfect.
- When i checked /sys/class/gpio/ the result is like this.
root@am437x-evm:/sys/class/gpio# ls
export gpio16 gpiochip0 gpiochip128 gpiochip32 gpiochip64 gpiochip96 unexport
Here i realised all the gpios are not reared here.
- So here my question is how to bring all the gpios readed under /sys/class/gpio/ ?
- Also here is the result got for me when i checked for gpio in dmesg for pin conflicts if any. but i couldn't able to figureout any useful thing out if . can someone help me any way in understanding these dmesg and do changes in dts so that all gpios will appear under my path.
root@am437x-evm:/sys/class/gpio# dmesg | grep gpio

I am requesting to please letme know if any procedure to get all gpios for any board.
Thanking you
