vi /etc/modules

for the right watchdog (wd1100) insert following

wd1100 sysctl_wd_graceful=0 sysctl_wd_timeout=30

The value 30 in sysctl_wd_timeout is measured in “seconds”. On some systems, a normal reboot (which stops the watchdog daemon and then triggers the hardware watchdog..) 30s is not enough for a complete shutdown. 45-60s may be more appropriete.

for reading on-board temperature chip add

scx200_acb 
i2c-sensor
lm77

after reboot you can read temps with

cat /sys/bus/i2c/devices/0-0048/temp1_input

Automatic try to reboot on kernel panic is always a good idea:

/etc/sysctl.conf:
kernel.panic=2

Additional info by B. Anderson:

To manipulate the LEDs on a WRAP board, you can use the following script:

#!/bin/sh
#
# Script to control the LEDs on a WRAP board
# Written by B.W. Anderson
# LED access code contributed by Josef Liska
# Note: there is currently no way to read status of LEDs,
# and 1&2 are not programmable separately. So the assumed
# state of LED 1 is on, and not programmable. It will be
# on at the end of this script, regardless.
#
# Full listing of LED control commands:
# led 3 on
# echo "A" | dd of=/dev/port bs=1 count=1 seek=62466
# led 3 off
# echo "L" | dd of=/dev/port bs=1 count=1 seek=62466
# led 1&2 on
# echo "A" | dd of=/dev/port bs=1 count=1 seek=62464
# led 1&2 off
# echo "L" | dd of=/dev/port bs=1 count=1 seek=62464
# led 1 on 2 off
# echo "H" | dd of=/dev/port bs=1 count=1 seek=62464
# led 1 off 2 on
# echo "D" | dd of=/dev/port bs=1 count=1 seek=62464
#
#
# Test for presence of command line options
if [ $# -lt 2 ]; then
	echo "Usage: $0 [n] [state]"
echo "where n = 2 or 3 and state = on or off"
exit 1
fi

if [ $2 != "on" ] && [ $2 != "off" ]; then
	echo " LED state must be on or off"
	exit 1
fi

case $1 in
	2) if [ $2 = "on" ] ; then
			echo "A" | dd of=/dev/port bs=1 count=1 seek=62464 2> /dev/null
			echo "LED 2 is now on"
		else
			echo "H" | dd of=/dev/port bs=1 count=1 seek=62464 2> /dev/null
			echo "LED 2 is now off"
		fi;;
	3) if [ $2 = "on" ] ; then
			echo "A" | dd of=/dev/port bs=1 count=1 seek=62466 2> /dev/null
			echo "LED 3 is now on"
		else
			echo "L" | dd of=/dev/port bs=1 count=1 seek=62466 2> /dev/null
			echo "LED 3 is now off"
		fi;;
	*) echo "Must specify LED 2 or 3"
		exit 1;;
esac
exit 0

Uses include turning on one of the LEDs upon boot completion or successful wireless connection.

info by Assaf Gordon (agordon88 [at] gmail.com)

This program allows to turn on, off, switch over or query the status of each led individually.

usage:

# wrap_led_ctl 2 off
# wrap_led_ctl 2 get
off
# wrap_led_ctl 2 on
# wrap_led_ctl 1 on
# wrap_led_ctl 3 swap
etc.

To compile:
Save this code as “wrap_led_ctl.c” on your host computer, run “gcc -o wrap_led_ctl wrap_led_ctl.c” and copy the resulting binary (wrap_led_ctl) to your voyage system.
