Topic: Cisco Meraki MR24 Support

We've replaced our MR16s and MR24s with MR32s and have no official use for the hardware due to Meraki's cloud licensing.  I've got OpenWRT running on a 16 and thought I would get this topic started to see if it goes anywhere.

The PCB is labeled UART and utilizes the same pinout as the MR12/16 devices.  So I am able to provide some info on the unit.
PIN 1 has a white arrow
P1->empty (VCC)
P2->RX
P3->TX
P4->GND

I see old support for PPC 44x devices and no recent changes so maybe a lot of this work is already complete?  Happy to help however I can.

Re: Cisco Meraki MR24 Support

Get Kaloz attention to get this device supported (if possible).

Re: Cisco Meraki MR24 Support

Thanks tmo26!  I see there is only one other Applied Micro APM82181 device in the TOH, the Netgear WNDR4700.  Unfortunately it doesn't look like it's supported despite natively running an OEM-modified OpenWRT, and the thread for it seemed to die off.

Re: Cisco Meraki MR24 Support

I built OpenWRT with ppc44x support and have tried booting openwrt-ppc44x-uImage with tftpboot from various addresses.  I guess either I don't fully understand where that location comes from or I have a bad uImage file that wouldn't work regardless.  I've used the MR16 location of 0x81000000, changing the boot file of course, and it goes all glitched and resets then boots from the Meraki image.  If I change the address around I get it to load and stop without resetting but that's all:

Re: Cisco Meraki MR24 Support

I got a little further but nothing spectacular.  I'm emulating the reset boot process where it looks for uImage, bluestone.dtb and uRamdisk files from TFTP.  I've created the uImage and uRamdisk files but I need the DTB file specific to this board.  Hopefully I'm missing something easy and I can pull it out of a memory location somewhere?  I grabbed a canyonlands.dtb and renamed it hoping to be in the right ballpark but no luck.

Re: Cisco Meraki MR24 Support

I had an idea and it seemed to have worked...to a point.  I loaded the Meraki stuff into memory using info from printenv commands, following the normal boot process, but then I used md to display the address and alleged length of the bluestone.dtb FDT file to the terminal, captured it, stripped it down to hex only, pasted it into HxD and saved it back to the TFTP server.  Whew!

Then I had the idea since I now have the alleged FDT and I know where the Meraki kernel and ramdisk are, maybe I'll just try booting their kernel with my ramdisk...but I get this error.

Doh!

Re: Cisco Meraki MR24 Support

I fired up another MR24 unit with an older build on it (4/2015 instead of 9/2015) but have the same limitations.  At the common Meraki rooting method doesn't work on either of these.  I have more which are probably even older but I'd have to find them.

Re: Cisco Meraki MR24 Support

And just in time, I found an original MR24 never installed with 2013 dates on it! FW 20-102298!  Let it boot up to find it drops me right into the system shell.

Re: Cisco Meraki MR24 Support

Good news, thanks to the hardware donation from @tbs_david I was able to get an UnOfficial build of OpenWRT going on the MR24 using a new device target for the apm821xx CPU. Flashing instructions and images can be found at https://github.com/riptidewave93/Openwrt-MR24 and https://github.com/riptidewave93/Openwrt-MR24/releases.

Next steps are to get a Wiki page up at https://wiki.openwrt.org/toh/meraki/mr24 and to start porting this device into the somewhat dead mainline ppc44x target, as a new nand sub-target.

EDIT: Wiki page up, and added to table of hardware

Re: Cisco Meraki MR24 Support

As always riptide, great work!  Hope other people out there can also benefit from your efforts.  End of Sale date on these units was May 2014 so the newest installs out there are already about 2 years old.  It'll be about time to swap them out for newer units with more modern features, and this should make for a lot of unused MR24s shortly.

Congrats on the progress!

Re: Cisco Meraki MR24 Support

As usual, riptide's work is flawless!  I was able to follow his instructions and get OpenWRT installed and sysupgraded on a MR24 that had the most recent Meraki firmware installed prior.  Wooo!!

Re: Cisco Meraki MR24 Support

Hi there, maybe a little bit of a silly question, does someone have an all ready bin file available?
I can't seem to get my compiling to work..

Thanks guys

Thanks a lot, should have found that myself..

Re: Cisco Meraki MR24 Support

I bricked one this week.  Found a dusty one in a corner and thought I'd get it running as a spare.  After following the flashing steps at the 'create UBI recovery partition' it rebooted and I haven't seen text on the serial interface since.  I flashed an MR16 to confirm my serial port was fine.  After flashing about 10 Meraki APs this is the first loss.

Re: Cisco Meraki MR24 Support

Hi guys, i am trying  to flash MR24. I get to the point to upload the iniramfs and sysupgrade files to the tmp folder on the device and couldn't make it. Do you have any ideas?
