The OM1P has a hardware watchdog that will reset the device every 5 minutes if it's not reset via a GPIO device.
[edit] Permanent Fix
install DD-WRT Micro_Redboot to disable the HW watchdog permanently
[edit] Workaround
After you got the route flashed you have 5 minutes to configure this.
Tested on:
- DD-WRT v24 Beta (08/03/07) std
- DD-WRT v24-sp2 (10/10/09) std
Go to your web interface add a custom script:
chdir / /sbin/gpio enable 3 echo "1" >/proc/gpio/3_out echo "0" >/proc/gpio/3_out echo "1" >/proc/gpio/3_dir echo "0" >/proc/gpio/3_dir
Then enable Cron under management and add this line Code:
*/4 * * * * root /tmp/custom.sh
Log into via console or web interface and restart cron:
stopservice cron && startservice cron
Not sure but i think you have to do this every time you restart the device.
Original hw-heartbeat.sh from Open-Mesh
#!/bin/sh # /sbin/hw-heartbeat.sh # send heartbeat to the hardware watchdog GPO="3" MCTL="4" [ "$(uci get node.general.hw_watchdog)" -eq 1 ] && { # i have no idea gpioctl dirout $GPO ; # set pin $GPO (3) to direction out? gpioctl clear $GPO # set pin 3 to logic 0 sleep 1 # wait one second/milli second? gpioctl set $GPO # set pin 3 to logic 1 logger -st ${0##*/} "signaling to the hw-watchdog" # write something to the log } #
