FreeBSD on Omega2 and Omega2+
-
Hi,
I am trying to get FreeBSD working on the 2+ board but suspect there wont be much difference for the 2.
Please see the following thread on the freebsd-mips list:
https://marc.info/?t=149417069200002&r=1&w=2
I am hoping here were some other Omega2/2+ owners/users out there who are interested in getting FreeBSD working on them and wants to try as well or has some ideas to help.
Below is as far as I have got using the freebsd-wifi-build stuff with some changes (see thread on freebsd-mips for more info) but basic build info:
