Ubiquiti NanoStation M5 flash chip woes (no settings saved after reboot)

Good Afternoon folks. I have been having a hard time trying to get openwrt running on a ubiquiti nanostation M5. I remember doing similar work a number of years ago, and most things went smoothly, but it seems they have really been making it more difficult recently.

Anyway, after some help from the ubnt forums I was able to get openwrt version installed on the nanostation M5 (XM chip version). Now the problem is that I am not able to persist settings across reboots. I have tried installing the 'factory' and 'sysupgrade' versions of the firmware listed here: https://openwrt.org/toh/ubiquiti/nanostationm5. In both cases I arrive back to the 'please set a root password' stage after any reboot. My searching for a solution has found two possible relevant articles. First there is a mention of having to do something in SSH before loading the 'second' sysupgrade image. (http://lede-ac58u.zyxmon.org/HowToFlashENG.html) However, these instructions are not dated and it seems they may no longer apply - my device does not seem to have the suggested binaries (ubirmvol, ubinfo) for example. The second scarier possibility had to do with some type of hardware bug, which it seems was fixed in DD-WRT but not openwrt? (https://dev.archive.openwrt.org/ticket/20982) The comments stop a couple years ago seemingly without any resolution? I think that this latter issue is the one, because the DMESG output I get is filled with lines like "jffs2: Newly-erased block contained word 0x19852003 at offset 0x003b0000".

Hopefully someone with more experience can help to shed some light on what the problem could be.

Your overlay is full. If you've installed packages on top of the ROM, you'll need to remove some that you've installed. If you still need them, you could try building your own firmware with those packages included.

If you're running without added packages, see, for example

First you have to have the old 5.5 bootloader for OpenWrt to run properly. This means downgrade to AirOS 5.5 using TFTP or ssh, then log in to the ubnt web interface and use it to again flash AirOS 5.5. Flashing through the web interface replaces the bootloader. Then you can flash OpenWrt.

TFTP flashing these is very simple. Hold down the reset button while you plug the power in and keep holding it until the signal LEDs start to flash back and forth. Then tftp put the firmware (old AirOS) to 192.168.1.20.

Note that the XM model only has 32M of RAM, so the 4/32 warning applies. You should not try to run anything major like OpenVPN.

Hi All,

I appreciate the replies you have provided. I will go over one at a time.

The filesystem sizes here are a little confusing to me. It looks like the '/' filesystem, which is usually what I would imagine is what defined the total space, still has some free space here. Additionally, the openwrt image is about half the size of the airOS image, so it would be strange that install size is the problem. I have only tried to load the wpad package, but settings get erased weather I do install it or not.

I am glad at least that it should be possible to do without the new bootloader. I believe the thread I linked was discussing fixing these bugs in the new bootloader, but I guess it is easier to just go back to the old version for now. In order to try to flash the old bootloader, do you know is a specific minor version is required? I have rendomly googled to find this airOS download for '5.5' , which is '5.5.11' (*http://dl.ubnt.com/firmwares/XN-fw/v5.5.11/XM.v5.5.11.28002.150723.1344.bin) - do you know is this will work? I will try it and get back to you.

performance should not be an issue, I only need wpad package to connect to EAP-GTC network in client mode.

Thanks all

Additionally, I have not been successful yet: when trying to flash the above firmware file over TFTP I receive the error "code 2: firmware check failed" - do you have a specific version file you have tried that worked for you?

/mtd/overlay is where all changes post install are kept.
/mtd/rom is read only and where openwrt is installed.

You need to free up some space by removing packages that you have installed yourself.

If you still need the packages then you need to build your own custom image with just the packages you require to keep the size small and increase the available space.

The advantage of a custom image is that /mtd/rom is compressed and included packages will use less space than if installed with opkg later.

Hi All,

To mbo20: sorry if I was not clear earlier. While doing these tests I had not installed any extra packages except during the first test - this would not seem to be the issue. I do appreciate your trying to help through.

I did manage to get airOS xm version 5.5.6 flashed multiple times through the web interface, and indeed this did the trick, and now settings are being saved. I appreciate your assistance in accomplishing this task!
