This is an openwrt fork for the UCSD M3 project (http://m3.ucsd.edu/sdr/). M3 is the first mmWave massive MIMO software radio platform.
The compiled OpenWRT Image can be found in here.
openwrt-m3-initramfs.bin is the RAM-based image that is used for initial temporary OS installation.
openwrt-m3-sysupgrade.bin is the flash image that can be used to make the OS permanent.
A detailed tutorial of installing OpenWRT on the Mikrotik routers can be found in IMDEA Mikrotik Research Tools.
Notably, for Ubuntu 22.04, the tftp server folder is located at /srv/tftp/ .
You need the following tools to compile OpenWrt, the package names vary between distributions. A complete list with distribution specific packages is found in the Build System Setup documentation.
