You can check and even manipulate GPIO lines from userspace without kernel source modification. To control SoC own GPIO just export required line by issuing: # echo X > /sys/class/gpio/export and then you can control line state (direction and level) via files in /sys/class/gpio/gpioX/ Wireless chip GPIO lines control a bit different. You can manipulate by any of chip registers via regidx and regval files located in /sys/kernel/debug/ieee80211/phyX/ath9k/. Just write register address to regidx and you can get and set register content by performing read and write operations with regval. # echo 0x1234abcd > /sys/kernel/debug/ieee80211/phyX/ath9k/regidx # cat /sys/kernel/debug/ieee80211/phyX/ath9k/regval > On 10/17/2014 11:44 AM, Adrian Chadd wrote: >> Hi, >> >> I'd just add some printf()'s in the openwrt board support .c source >> file.
