Legacy Open Mesh: How do I Flash an Access Point in Mac OS X (beta)?



How do I flash an access point in Mac OS X?


  • Datto Access Points


Note: The OS X flash utility is not currently compatible with the following models: A40, A60, OM2Pv4. If you need to flash one of these models, please use the Windows flash utility.

First download the ap51-flash utility.

Next download the .bin (and version) for the model you are trying to flash from this directory: http://files.cloudtrax.com/downloads/firmware/

Note: You need to download the .bin.signed version of the file for the OM5P-AC and MR1750v2.

Now go to your Apple Menu -> About This Mac -> System Report... -> Network and find your Ethernet adapter in the list. Note the "BSD Device Name". It should start with "en", such as en0.

Make sure your device is connected to the computer via an Ethernet cable, but unplugged from power. It does not matter which Ethernet port you use on our devices.

Open a terminal window and type:

cd Downloads

sudo chmod 777 ap51-flash-osx
sudo ./ap51-flash-osx en# firmware.bin

These commands require administrator privileges. If you are prompted for your computer password, please enter it. Make sure to replace "en#" with the actual "BSD Device Name" of your network adapter and "firmware.bin" with the actual filename of the firmware file downloaded.

You may see a message similar to `Error - can't write to pcap socket`. You can ignore those messages. Plug the power cable into the Open-Mesh device.

If you see `Error activating pcap handle` this means the AP isn't yet ready to accept the command you've typed, and you'll want to continue sending the previously typed command until the AP accepts it. Unlike the Windows flash utility, the Mac utility won't sit and wait for the AP to accept the command after typing it once. 

Within 1 minute you should receive notifications that the flash is taking place. Within 2 - 3 minutes after that, you should get a message advising you to disconnect the device. If you aren't advised to disconnect the device after 5 minutes, you should assume the device has been flashed and disconnect it.
