The Kirkwood processor has a substantial amount of pins able to be configured as GPIOs. I'm only seeing
$this->bbcode_second_pass_code('', '
[root@samba gpio]# cat /sys/kernel/debug/gpio
GPIOs 0-31, orion_gpio0:
gpio-10 (USB VBUS ) out hi
gpio-22 (status:green:health ) out lo
gpio-24 (status:red:fault ) out lo
gpio-27 (mvsdio cd ) in hi (act lo) - IRQ edge (clear )
gpio-29 (Eject Button ) in hi (act lo) - IRQ edge (clear )
GPIOs 32-49, orion_gpio1:
[root@samba gpio]# echo 1 > /sys/class/gpio/export
-bash: echo: write error: Invalid argument
')
From what i can tell the board exposes a few on the edge and the SD card slot is GPIOs as well. How do I access them in the OS? I'm a hardware guy i can do amazing things withthe gpios, I just don't know where to go from here.
