imx7s warp ums 0 mmc 0 ** Invalid partition 1 **

I have an imx7s eMMC  that refuses to enter ums mode. With previous boards issuing ums 0 mmc 0 it will produce a virtual SD card in which I can dd a file system on to. 


This one whoever comes up with " Invalid partition 1 ** after entering ums 0 mmc 0. This as with other boards I have are based on the Warp7 and have totally blank eMMCs so I don't want to brick boards unnecessary. Any help to get this behaving again would be appreciated, but it looks like it may only be through u-boot mmc functionality.
