| + | |||
| + | discussion with Erik Benada explaining that : | ||
| + | |||
| + | <code> | ||
| + | with conversion of Orion architecture to gpiolib it is now possible to | ||
| + | turn off power LED blinking from userspace - eg. after booting is | ||
| + | finished. You can also turn on power LED blinking before you shut down the system to let user know system is going down. | ||
| + | |||
| + | To turn off power LED blinking after booting is finished: | ||
| + | echo 1 > /sys/class/gpio/gpio3/value | ||
| + | |||
| + | To turn on power LED blinking before shutdown/reboot: | ||
| + | echo 1 > /sys/class/gpio/gpio4/value | ||
| + | </code> | ||
| + | |||
| + | Disk access leds still don't work properly in 2.6.32... | ||
| + | Following code configures SATA gpio, not ARM gpio | ||
| + | writel(0x00000050, mmio + MV_GPIO_PORT_CTL_OFS); | ||
