==== some hints of using voyage on WRAPs ====

  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.


==== Controlling each led individually ====
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:
<file>
# 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.
</file>

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.
