how to make the router button work? I have a router ,firmawre image openwrt-ramips-rt305x-wr512-3gn-4M-squashfs-sysupgrade.bin ,but the button didn't work ,I follow the wiki how to log $action of button ,but have nothing...can someone give me some suggest? Thanks~

as control of leds and buttons are highly hardware dependent, you have to gather infos about the gpio of your router.
Hint to search openwrt / google : gpioctl button led sysctl
as well as any infos o your routers I/O
there is alot of code aout there dealing with routers I/O, so go and learn
example : https://forum.openwrt.org/viewtopic.php?id=28193
good luck

thanks~I find the reset of gpio10 can pressed tx value 0 and unpressed rx value 1 ,but how can i use it to reset??I have mkdir /etc/hotplug.d/button/00-reset and input so code,but it doesn't work!
scripts like this
#! /bin/sh
[ "$BUTTON" = "reset" ] && [ "$ACTION" = "pressed" ] && {
reboot
}

did you check ?
http://wiki.openwrt.org/doc/howto/hardware.button
http://wiki.openwrt.org/doc/uci/system
maybe you have to query the button directly by scripting with gpioctl ( eventually install the packet) and put that script in a cron job.

Hello, I have the same problem with buttons in wr512-3gn (the buttons didn't work)
I put a simple script in /etc/hotplug.d/button/buttons and don't see anything in logread. The script is:
#!/bin/sh
logger $BUTTON
logger $ACTIONI try to see the file /sys/kernel/debug/gpio , but i can't find anything about buttons :

root@OpenWrt:~# opkg list_installed | grep gpio
kmod-leds-gpio - 2.6.39.4-1OUX! I don't have any packages with "button".... I install this packages
root@OpenWrt:~# opkg install kmod-input-gpio-buttons kmod-input-gpio-keys kmod-input-gpio-keys-polledNow the RESET button work, but not the MODE button. This is OK for me 
google search with : wr512-3gn gpio button

......"Also some gpios are shared with the second uart, 7,8,9,10 if the remaining of the port is still used as GPIO. So could work depending on where GPIO8 is?
You defined GPIO 0 and 8 as input buttons named WPS and WPS2, are they exposed somewhere, on a testpoint?"
if they arent supported in you openwrt version you may test the buttos directly running a script in cron using "gpioctl get <pin>"
