Meru HSMM Project

We have a bunch of Meru AP's that were donated to our club. This project exists to serve as a repository of any information we obtain during our quest to shoehorn OpenWrt on the hardware.

Notes:

• Units use standard 3.5mm 3-pole Headphone Jack for serial port. It is 5 Volt tolerant and does not require a level converter.
• Units run a custom version of RHEL and appear to use uBoot for the bootloader.
