It's really tedious and takes a while (an hour or 2 per node), but I've only got 30 or so to flash so maybe it won't be too bad. Twisted Evil

WOW! 30 nodes to flash.... Not so sure I would want to hang around for that one. I would put 5 NICs in a computer and flash 5 at a time Smile

I hadn't thought of that. I wonder if it would work. Just edit the flash script to use the correct adapter (not eth0). Hmm.....

Yuppers! Just open 5 console windows and have them each flash a node.

Just a quick note; I've got a stripped down PC (spare parts basically) with 5 NICs in it and I'm flashing 5 nodes right now. I took a couple snapshots that I'll try and post today for giggles sake. This should make it go a little faster! Cool

Has anyone else been able to confirm this? Has Meraki actually gone ahead and added new firmware that prevents flashing with third party firmware?

I wouldn't be the least bit surprised. They boobytrapped the new Outdoor model, so it's only a matter of time before they do the same to the Mini (assuming they haven't already).

Meraki booby trapped the Redboot. It will reboot itself before you can flash it.

Meraki actually handicapped RedBoot so it can't accept any connections on Telnet so it can't be reflashed that way. The only way to reflash it is to reinstall RedBoot. They clearly reloaded it somehow, so if someone can figure out what they did, we could perhaps reflash it.

bmph8ter: How did you manage to downgrade it? With TFTP? I'm wondering about this.

You can ssh into the Meraki and create edit the /storage/config.local file with whatever you want; in my case:
Code:
echo "firmware.mips.version 6-9163" > /storage/config.local
locked the units to firmware version 6-9163 (was 8-14712). Reboot the unit, let it connect to the 'net and 'upgrade' and you are all set. I found a post at the meraki forums that pointed me in the

. It was really pretty easy once I figured it out; just kinda time consuming. So far, I've flashed about 15 units using this method and have about 15 to go once we get them swapped out.

I'm not real sure what they did to the firmware. My guess (just a guess) it that it basically had the same effect as turning off boot_wait for openwrt; so you have no time to send firmware.

I took a bit of fiddling with different NICS, but I got it running smoothly after a few swaps. Thanks for the suggestion; it's saved me TONS of time so far.

I'm exploring Flashing a Mini with the Ubuntu 7.10 live CD.
I'm new to Linux, and feel silly asking such basic quiestions.

Can I save the command scripts to a file and
pipe them to the terminal?

Or if I cut and past the scripts from the Web page,
Do I have to do it line by line or can I paste all the
lines of scripts at once.

If you save the files, you can just 'run' the flash script from a terminal window;
Code:
./flash


That will run the script for you and use the easyflash and firmware files in your current working directory.

I can't seem to connect anymore to the internet when I use the Ubuntu CD. I'm plugged in, but it refuses to "see" the connection. I'm at a loss. I'm doing the exact same thing I always did, following the instructions (got them printed out). No need to try and help troubleshoot, as I'm useless at Ubtunu.

Is there ANY way to flash the Merakis in another way? I know Windows does not work. Is there a pending fix? I'd like to get my nodes back up but they got hung up during a switch back from "test" to Beta 1. I'll never go back to "tes" if I get them fixed ... Sad

So the Meraki gets new images from home base, then flashes itself, and if the checksum matches, it reboots to the new image.

Any way to cause the Mini to pick up an image elsewhere, for example by changing the TFTP or FTP host it picks it up from, so that we could easily let the units re-flash themselves over to ROBIN?

If you're using the Ubuntu LiveCD, just download the files on your Windows computer. Put in the Ubuntu CD and reboot. Then, click places & computer and your hard drive should be listed. Open a terminal window and go to that location (cd /media/disk/blah/blah) and then run the command listed above. That's actually what I did on my laptop as the wireless isn't picked up by Ubuntu, and I needed the wired connection for the Meraki.

@ danejasper Sort of. I actually think that it verifies the checksum/hash several times throughout the process. I'm sure that with enough hacking it would be possible, but I think the amount of work required would turn it into a 'why bother'. Trying to get the robin firmware to match the meraki firmwares computed hash would be next to impossible I think. It's really pretty easy to just use the ap51 flash utility or the Ubuntu LiveCD.

The challenge is that the devices are in the field - many on street light poles. To take them down to flash them requires traffic diversion at a very early hour, two staff, a bucket truck, etc.

This is why a remote solution would be nice. We can ssh in - then if it would be possible to config the device to re-flash itself, that would would be nice.

This would also cut out some of the challenges that folks have had with Windows, timing, how long it takes, etc - just let the Meraki do it's own flashing, as it does to maintain itself today.

That said, I know little about their download and flash process aside from looking at the script itself, so I have no real insight on feasibility.

How do you downgrade the meraki firmware to 6-916. and how do you find out that you are currently running 8-14712?

thanks in adv for sharing.

Try using an Ubuntu LiveCD; I had lots of problems flashing with Windows, but the Ubuntu disk helped a LOT.

cosme - To find out what firmware version you're using, power the Meraki up, associate with it and open

in your browser. Click the 'advanced' link and it should show your firmware version in the lower corner. If it doesn't, you will need to use an SSH client (I use Putty) to connect. Use the same address as above (10.128.128.128) and login with username 'meraki' and the password will be the units serial number 'xxx-xxx-xxx'. Once you are logged in you can type
Code:
cat /MERAKI_BUILD
and it will tell you what version you are running.

If it is the 8-14712 version, you will not be able to flash it without some additional work. This is where you will need to type
Code:
echo "firmware.mips.version 6-9163" > /storage/config.local
to downgrade the firmware first. Once you've typed that command, you can logout (just type 'exit') and power cycle the unit. Once it's booted up, reassociate with it and use the first steps to check and see if it has downgraded the firmware yet; opening
