Hello,

As title says, I have SC668S-EM and I want to export GPIO_95 and GPIO_97. (Android 11)
echo 95 > /sys/class/gpio/export and echo 97 > /sys/class/gpio/export does not work.
How to do that?

Thanks!

What’s the PIN numbers of these two gpios? PIN113 PIN114?

That’s right, PIN113 and PIN114

I can reproduce this phenonmenon, I will try to operate these two gpios by driver,
please wait.

I find that in the source code the gpio95 and gpio97 are used for other functions, so we can try to release them and try again. Please refer to this to release the gpio95 and gpio97 and try again.
