On link https://www.kernel.org/doc/Documentation/gpio/sysfs.txt it is talked about gpio
It has comments: Note that standard kernel drivers exist for common "LEDs and Buttons" GPIO tasks: "leds-gpio" and "gpio_keys", respectively. Use those instead of talking directly to the GPIOs; they integrate with kernel frameworks better than your userspace code could. What category does GPIO in BeagleBone Black belong to? What is about the built-in GPIO in my AM3358 SK board? Thanks, On Mon, Sep 7, 2015 at 10:19 AM, RJ Wang <rxjw...@gmail.com> wrote: > Thanks. I just got feedback from e2e forum.
