#9519 new defect

Trunk does not create a sysfs interface for GPIO on atheros boards.

Reported by: sebkinne Owned by: developers
Priority: normal Milestone: Barrier Breaker 14.07
Component: base system Version: Trunk
Keywords: gpio sysfs gpioctl Cc:


To controll GPIO pins, gpioctl is apparentally a legacy solution to changing the status of gpio pins. Trying to use sysfs to interact with said pins (eg. echo 3 > /sys/class/gpio/export)does not work as the "/sys/class/" directory does not show any GPIO directory, only a gpiodev directory.

Not being able to control GPIO pins means that many routers automatically reboot due to a watchdog chip.
