I purchased a box of used 10 Rocket M5s from eBay. Only one was an XW and the rest XM, so score so far. I'll just keep the XW for a survey node.
One of the nodes appears to have a flash issue. I was able to put 3.16.1.0 on it. When I try to set the node name, password, and distance, I get an error when saving. Looking at the initial page I see Flash shows 0kb free. When I compare to other nodes, they have 2mb+ Flash free.
Is there a way I can clear out the flash? My guess is perhaps that a good portion of the flash has gone bad and been marked that way, limiting the node to too little free space left to save the config or anything else (and perhaps even the original firmware).
Any thoughts? I have the supportdata.tgz file from the node: https://dl.dropboxusercontent.com/u/9532089/AREDN-Mesh-temp/supportdata-NOCALL-201605110503.tgz
I have tried to flash it again with the same or older versions, but no luck. It says it is flashing the firmware, reboots, but always boots back to 3.16.1.0.

Bad Rocket M5?
Theme by Danetsoft and Danang Probo Sayekti inspired by Maksimer
Linux is booting, so it's not 'bricked' per se with the typcial XM5.6 downgrade issues. This looks like bad memory still smoking. From the data dump, Linux is unable to initialize and write to flash space to create the "jffs2" filesytem. See https://wiki.openwrt.org/doc/techref/flash.layout . This is the free flash space used to save all the unique config files, etc. after initial boot.
This free flash space is mounted directly and you can see with a "df" command as "/overlay":
Filesystem 1K-blocks Used Available Use% Mounted on
Your device-> /dev/mtdblock5 2752 2752 0 100% /overlay
know good device-> /dev/mtdblock5 2752 332 2420 12% /overlay
In your case, there was 0% free from the start, even after linux tried to initialize and write to it.
Your linux kernel is looking to create this file system at partition "rootfs_data" in flash and shows it knows the correct definition for the AREDN image:
[ 0.560000] 0x000000000000-0x000000040000 : "u-boot"

it has also been seen in another case where the flash went bad.
Unless you are positive this device wasn't running 5.6 I would suggest following the AIROS 5.6 to 5.5 downgrade procedure (requires serial access)
KG6H, If this is the case, then a process to recover could be:
1) tftp and load the AirOS v5.6.x latest version
2) boot to UI and then from UI downgrade to AirOS v5.5.x
3) then load AREDN again...

It has been my experience from reading the threads and testing that once you get into this AIROS 5.6 boot loader with a non 5.6 image running (like AREDN) that simple TFTP with the reset button doesn't work.
Hi Folks!
Does anyone know the JTAG pinout and interface parameters for the Ubiquiti M2 Rocket?
My node is bricked and I need to help Lazarus arise.
