Latest kernel has three tools lsgpio, gpio-hammer and gpio-event-mon, all these tools opens the device node under /dev/gpiochipN. Does v4.4 kernel has any similar tools to control GPIO pins by using /sys/class/gpio/gpiochipN? If not, can someone point me how the GPIO pins were controlled in the older kernel(which supports /sys/class/gpio)? Thanks -------------- next part -------------- An HTML attachment was scrubbed...
