Right here a quick low-down on what i have found about the shield booting
when you power on the Shield it loads OCTEON eMMC stage 1 bootloader this then give control over to OCTBOOT2BIN which is stage 2 the build time that my two Shields display are build time Mar 2015 and both are on 1.51 sp1 U-Boot 2013.07 (Development build, svnversion: u-boot:exported, exec:) (Build time: Mar 27 2015 - 10:49:38) All the trouble people seem to have are with builds dates 2014, i think this could either be firmware version RC1 or the beta firmware stage 3 loads u-boot-octeon_rhino_itus7x.bin U-Boot 2013.07 (Development build, svnversion: u-boot:exported, exec:) (Build time: May 04 2015 - 15:37:16) two things here 1. the name of stage 3 files seemed to have been change from u-boot-octeon_sff7000.bin to u-boot-octeon_rhino_itus7x.bin 2. the build time for this file is now May 2015 the good new is that both these files can be copied to the Shield. The Shield seemed to have trouble loading either the stage 2 file or stage3 file from the memory. The only way to correct this is with a console cable I prefer a usb console cable. Here is my start up screen stop just after loading stage3 OCTEON eMMC stage 1 bootloader Partition: 1, start: 0x0000000000000800, size: 0x0000000000200000 Reading 470976 bytes. ...................................................................................................................

Hi seanmcne
What version were you running RC or 1.51sp1? I have just fixed orl1pcc Shield after many hours of work and learning, but this sounds the same , all files missing or deleted, i'm thinking that may be the Shield is trying to do a firmware upgrade or some how the system restore script is being called which deletes all files except itusrestoreimage. I have found that if the restore script is run and a restart is done then the Shield has not files, but if the restore script is run and when it asks for a restart you do a factory restore instead (power down , hold pin in for 30 seconds whilst powering back up ) the Shield boots up with files in the right place. The trouble is once files are missing you have to copy over the overlay folder and run the restore script. I'm still learning what the Shield is doing on start-up, but there is a fail safe mode which is read only but is only available during loading bootstage3. if you need help sorting just ask but i'm away for 4 day as from today.

This post was updated on .
The current factory_reset secript has a major problem:
it DELETES the boot images without any check if the new updated 1.51SP1 actually exists 
if [[ `df | grep -c overlay` == "1" ]]; then
umount /overlay
fi
sleep 1
mkdir -p /factory_reset
sleep 1
mount /dev/mmcblk0p1 /factory_reset
sleep 1
cd /factory_reset
sleep 1
rm ItusrouterImage
sleep 5
rm ItusbridgeImage
sleep 5
rm ItusgatewayImage
sleep 5
cp ItusrestoreImage ItusrouterImage
sleep 10
cp ItusrestoreImage ItusgatewayImage
sleep 10
cp ItusrestoreImage ItusbridgeImage
sleep 10
cd /
sleep 1
umount /factory_reset
sleep 1
umount -a
sleep 1
reboot -f
So I made an update: First of all if /tmp/ItusrestoreImage does not exist, this script will simply exit (stop) to run. Second if it does exist (checked twice) then it will make a backup of the existing images before any update. Third I am using hard folder references instead of relative. This prevents issues in case of starting this script outside the root.
# Script asumes that the ItusrestoreImage is located in the /tmp folder
# mounting folder for the boot device
factory_reset_folder='/tmp/factory_reset'
make_Imagebackup () {
#
# function to create a backup of the current boot image to a sub-folder
# does not run in case th
#
if [ -r '$factory_reset_folder/$ImageName']; then
{
echo "Creating backup of the $ImageName"
mv '$factory_reset_folder/$ImageName' '$factory_reset_folder/backup'
}
else
{
echo "Unable to find $ImageName in $factory_reset_folder"
}
sleep 5
}
update_Image () {
#
# Updates boot image ONLY in case the ItusrouterImage exists in /tmp
# ABORTS this script in case ItusrouterImage check fails.
#
if [ -r /tmp/ItusrouterImage ]; then
{
echo "Creating backup of the $ImageName"
cp /tmp/ItusrouterImage '$factory_reset_folder/$ImageName'
}
else
{
echo "Replacement ItusrestoreImage does not exist in /tmp - ABORDING"
exit 1
}
sleep 5
}
# check for the ItusrestoreImage
if [ ! -r '/tmp/ItusrouterImage' ]; then
{
echo "Replacement ItusrestoreImage does not exist in /tmp - ABORDING"
exit 1
}
# Remove old mounts
if [[ `df | grep -c overlay` == "1" ]]; then
umount /overlay
fi
sleep 1
mount /dev/mmcblk0p1 $factory_reset_folder
# Check for the backuip folder in the mounted partition
if [ ! -d '$factory_reset_folder/backup' ]; then
{
mkdir '$factory_reset_folder/backup'
}
sleep 1
cd $factory_reset_folder
sleep 1
# Backup and updates the router image
ImageName='ItusrouterImage'
make_Imagebackup()
update_Image ()
# Backup and updates the bridge image
ImageName='ItusbridgeImage'
make_Imagebackup()
update_Image ()
# Backup and updates the gateway image
ImageName='ItusgatewayImage'
make_Imagebackup()
update_Image ()
# Backup and updates the restore image
ImageName='ItusrestoreImage'
make_Imagebackup()
update_Image ()
sleep 1
umount 'factory_reset_folder'
sleep 1
umount -a
sleep 1
reboot -f
No more: Shield Pro v1, Chaos Calmer, FW 1.51 SP1
