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 UBOOT_KERN_LOADADDR="0x80001000" UBOOT_KERN_STARTADDR="0x80001100" X_DTS_FILE=OMEGA2P.dts KERNCONF=MT7628_FDT ../freebsd-wifi-build/build/bin/build ralink uboot The U-Boot build image looks good: [mike@f64-current ~/omega2/src]$ UBOOT_KERN_LOADADDR="0x80001000" UBOOT_KERN_STARTADDR="0x80001100" X_DTS_FILE=OMEGA2P.dts KERNCONF=MT7628_FDT ../freebsd-wifi-build/build/bin/build ralink uboot Checking - uboot-mkimage-2010.12 ..

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?
