I am getting further - i think the build script for ralink doesnt
extract the infomation properly for the loader and starting address:
https://github.com/freebsd/freebsd-wifi-build/blob/e3303a6e5ee13e096bdd3769e2e7e523fefb6f51/build/bin/build_ralink
I have now rebuilt the image files with:
UBOOT_KERN_LOADADDR="0x80001000" UBOOT_KERN_STARTADDR="0x80001100"
X_DTS_FILE=OMEGA2P.dts KERNCONF=MT7628_FDT
../freebsd-wifi-build/build/bin/build ralink mfsroot
UBOOT_KERN_LOADADDR="0x80001000" UBOOT_KERN_STARTADDR="0x80001100"
X_DTS_FILE=OMEGA2P.dts KERNCONF=MT7628_FDT
../freebsd-wifi-build/build/bin/build ralink fsimage

X_DTS_FILE=OMEGA2P.dts KERNCONF=MT7628_FDT
../freebsd-wifi-build/build/bin/build ralink uboot
The U-Boot build image looks good:
[mike at f64-current ~/omega2/src]$ UBOOT_KERN_LOADADDR="0x80001000"
UBOOT_KERN_STARTADDR="0x80001100" X_DTS_FILE=OMEGA2P.dts

Uncompressing Kernel Image ... LZMA ERROR 1 - must RESET board to

At this point the board resets/reboots.
I have tried using the kernel.MT7628_FDT.lzma.flash instead but have the
same LZMA Error.
I rebuilt before this post just in case there was an actual error with
the files/usb mem key but still get the same problem.
Is there a different lzma format I should be using? (I have just let the
build scripts create these).
Bit of info from file in case of use:
