Hi,

I am trying to get FreeBSD working on this board - I think I am almost 
there in getting it working but need some help please.

I have followed instructions from the freebsd-wifi-build and *think* I 
have got everything correct - I am trying to do this on a CURRENT setup:

FreeBSD f64-current.mw.office 12.0-CURRENT FreeBSD 12.0-CURRENT #0 
r317887: Sun May  7 03:20:34 UTC 2017 
mike at f64-current.mw.office:/usr/obj/usr/src/sys/GENERIC-NODEBUG amd64


$ cat ~/.freebsd-wifi-build-settings.cfg
X_SKIP_MORE_STUFF=YES
X_EXTRA_SRC_CONF=~/omega2/src.conf

$ cat ~/omega2/src.conf
WITHOUT_CLANG=YES
WITHOUT_CLANG_FULL=YES

Create flash:

dd if=/dev/zero bs=$(( 0x200000 )) count=1 of=${X_FLASH}
dd if=kernel.MT7628_FDT.lzma.uImage of=${X_FLASH} conv=notrunc
dd if= mfsroot-ralink.img.lzma >> ${X_FLASH}


$ readelf -h kernel.MT7628_FDT | grep Entry
   Entry point address:               0x80001100




Now on the omega over serial - I didnt get the network expansion doc 
thing so am doing stuff with usb rather than tftp

I am not 100% sure about the 0x80001100 and the fatload and have tried this

Omega2 # fatload usb 0:1 0x80001100 /kernel.MT7628_FDT.lzma.flash
*

At this point nothing happens and console hangs - note in OMEGA2.dtsithe 
console is set to ttyS0:

bootargs = "console=ttyS0,115200";




I have also tried with just kernel.MT7628_FDT and kernel.MT7628_FDT.lzma 
but both fail:

Omega2 # fatload usb 0:1 0x80001100 /kernel.MT7628_FDT.lzma.uImage

A few comments on the hardware for anyone who wants to get one:

Get the expansion dock with serial port access - the power dock does not 
provide serial access - i think it is possible to use an ftdi ttl serial 
chip/cable but have not tried.

Stupidly I forgot this only has wifi access so you are not able to tftp 
boot this without getting the ethernet network expansion but loading 
stuff up from a usb memory stick is seem fine from u-boot.

I do not think that it is possible to boot from the SD card on the 
Omega2+ - which is a shame.

Thanks for reading,

Mike.
