M.2 NVME not detected by Ubuntu server or Debian images, but detected by Android image



I have a Toshiba OCZ RC100 M.2 2242 NVME board which works fine and is detected by the Android 7.1 image, but not by either the Debian or Ubuntu Server images - in fact no M.2 PCIE device is detected by the debian/ubuntu images (I also have an M.2 ethernet card which I know is working)

I need to use Ubuntu server for my project

Is there something missing in the device tree/uboot that I should change?
