Updated 7/25/2020: New Gihhub Org created to hold the repositories for both the code and the opkgs.
This update brings the system to kernel 5.4.52, updates the toolchain to musl 1.2.0, updates gcc to 10.x, and fixes the sysupgrade system, fixed the issue with luCi where the "MTD" device was invalid (we don't have MTD devices)

*******************************************

This thread is for the Itus Networks Shield Firmware v2 that I created.  This firmware is based on OpenWrt SNAPSHOT r13926+6-f94b09867d, built from the main branch.

This firmware only makes use of the BRIDGE and ROUTER modes, leaving the GATEWAY mode as a Recovery mode, or you can leave it as it came from Itus.  I would HIGHLY suggest the Recovery Mode option (instructions below)

These images DEFAULT to a 192.168.1.1 IP address.  These images DEFAULT to WAN on eth0, LAN on eth1 and eth2

This will remove the existing Itus Networks operating system and replace it

This Firmware is a BASE OpenWrt image.  It contains only the basic bootstrapped packages (include luCi) to get the system booted.  After the system is booted, you can add packages via opkg or luCi.

It is recommended you have a console cable, if available.  I've tested this many (many) times, but solar storms happen.

Instructions for Installation:

Installing the Recovery Image to Gateway (RECOMMENDED)

Download the file openwrt-octeon-itus-itusgateway-initramfs-kernel.bin

On the Shield:

mount /dev/mmcblk0p1 /mnt          ( NOTE: If you are already using a previous v2 firmware, this will be: mount /dev/mmcblk1p1 /mnt )

scp openwrt-octeon-itus-itusbridge-initramfs-kernel.bin to /mnt/ItusgatewayImage

Unmount /mnt so we don't potentially damage it...
umount /mnt

Place the switch in the (G)ateway mode, and reboot (Original Firmware owners use: reboot -f      v2 users can just use: reboot)

The system should be booted around 60-70 seconds.  The (M) light on the front panel will turn CYAN/GREENISH-BLUE when the boot is complete.  The network should be up at that point as well.

Congratulations!  You have successfully installed your new Recovery system..

This image is EXACTLY the same as the Router and Bridge images, except it does NOT use storage - it is completely RAM resident.  It's a LiveCD install, if that makes it easier to understand.  ANY CHANGES you make to the system (Network, Packages, etc) will NOT survive a REBOOT!

This is a good way to get a sense for the system, you can install packages, configure them, bring the networks up and down, etc, just note the above about reboots

Now that you have a stable recovery platform, it's time to move to the next step.  

Prior to this point, you've replaced the non-functional Gateway image with a working image.
ANYTHING FROM THIS STEP IS DESTRUCTIVE TO THE ORIGINAL ITUS FIRMWARE - YOU HAVE BEEN WARNED
