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.
