Hi Mori,
When I compiled the world/kernel etc I used:
X_DTS_FILE=OMEGA2P.dts KERNCONF=MT7628_FDT
../freebsd-wifi-build/build/bin/build ralink buildkernel
I checked the serial stuff was the same as the other configs in:
https://github.com/freebsd/freebsd-wifi-build/
and they looked the same.
The OMEGA2.dtsi file has:
chosen {
bootargs = "console=ttyS0,115200";
};
And mt7628an.dtsi has: serial0 = &uartlite;
I dont think im getting as far as worrying about the serial console at
the moment and need to get the kernel to uncompress first.
Mike.
