Hi,

I just dig out some ubiquiti nodes that I havent used for a couple of years and thought I would update them. I downloaded the various versions of the firmware and started to upload them viaa the admin page.

Just realised that on one of the Nanostation M2s, I have uploaded the firmware for a bullet/loco

Is it now bricked?

Thanks

So device has rebotted and appears to be working as an AP with and SSID of meshnode and is polling for a dhcp address. I have connected it to a router and it works perfectly as an AP.

Just cant get to any interface.

Any suggestions?

Do nanostations have a jtag interface or serial?

Cheers

Jon

Reload via TFTP2

You may need to reload the firmware using TFTP2 from the bootloader.
What version of AREDN (bullet) did you put on it? 3.16.1.1?
Chances are, you can probably still connect to the node try 192.168.1.1:8080 from your computer and attempt reload of the proper Firmware from the web interface - if not, TFTP. There is an internal serial interface available but I don't think you will have to go that far.

Hard reset first by holding the reset button during power up and hold for 30-60 seconds until the status lights blink in combination 1&3, 2&4. Then power cycle and try to connect to the node again.

Hi,

Hi,

I somehow managed to upload the 3.16.1.1 bullet firmware to a nanostation m2. Need to pay more attention in the future!

I did try resetting but will give it one more go..

I have been reading this: https://community.ubnt.com/t5/airOS-SDK-Custom-Development/AirMAX-Device... has got me to the point of a being able top TFTP a .bin file but trying the correct AREDN file says "firmware check failed! (-2)"

Hard reset got more life out

Hard reset got more life out oof it, thanks.

Cant get to any interface though apart from serial. At the serial console I have the Aredn prompt with roo@NOCALL

I have run an nmap scan against it and there are no open ports and I cant ping it. It is however, handing out DHCP IP Addresses.

So can I enable the webinterface from the command prompt?

If not, I am thinking a TFTP upload is going to be the only option.

Any suggestions on firmware versions to try and where to get them from?

Development Firmware

If you have a NOCALL login, you should be able to get to it with you web interface on 192.168.1.1
The development firmware can be found here:
http://downloads.aredn.org/snapshots/trunk/ar71xx/generic/
You are supposed to be able to directly TFTP2 these files to you node. Be sure to use the "Factory" version, not the upgrade).

I just tried TFTP again and it looks to be installing!

Fingers crossed I have got it back.

It looks like it has worked but when I setup the node, it wont save the settings. a reboot brings it back to NOCALL

OK - you should be able to log into the NOCALL node, set it up and download the correct firmware for that model.
I assume you remember how to log in to a "fresh" node : login=root pw=hsmm

Yep, managed to login ok but

Yep, managed to login ok but when configured, saved and the rebooted it went back to nocall.

Found a step in the TFTP flashing to copy environmental variables hadn't worked.

Now all solved and working well

Thanks for your help

Saving Settings

Have you looked to see "why" it won't save settings? You need to move the distance parameter to greater than 0. 1 mile is good enough.

Sure would be nice to have an installer program that automatically detects and loads the proper file (bullet, nano, etc) via TFTP, huh?!?

I just hope if anyone takes the time to make such a program it is made multi-platform to support Linux, Mac and Windows so everyone in the community can use it and it can be used as part of an automatic flashing workstation (I envision some day being able to just plug a Pi into a device and its done for me including pulling the reset lines high which would make it especially useful at events where you need to mass provision)

Umm good idea Darryl!

Wonder where I've heard that before? Oh wait - isn't there an "old" ticket out there somewhere??

I don't recall a ticket and I

I don't recall a ticket and I'm not able to find a ticket on quick searching. I do however recall there was certainly a number of comments very similar if not exactly the same as above when a member of the community created the U-Boot test tool but it was made windows only.

I do have a ticket open for setting a supported list of browsers in AREDN, maybe a ticket might be good to have AREDN adopt an operating system support as well for any tools AREDN considers developing (if any)
