Not to load uInitrd is expected as it's the default boot script at u-boot.

The only weird thing here is the "Bad image type", probably because u-boot is calling ""source ${loadaddr};" instead of bootm or similar.

[John Rigby (jcrigby)]

Changed the default boot command to fallback to pxe:

if usb start; then
    set autoload no;
    bootp;
    pxe get;
    pxe boot;
fi

To get this behavior none of these files can be on the fat partition: boot.scr, uEnv.txt, uImage.

 Isn't it "pxecfg get" and "pxecfg boot"?
