Hi Dirk

Finally .................
I must apologise the issue looks to be my fault ...
I tried a 3rd USB cable and I manage to create an image using the Linux software from
https://github.com/raspberrypi/usbboot

I am shocked... One cable to be faulty I can understand - 2 cables to be faulty ...

Hi Dirk

Thank you for your reply
Yes I can confirm I did install RPiBoot.exe which I got from
https://www.raspberrypi.org/documentation/hardware/computemodule/cm-emmc-flashing.md
which I installed on both windows 7 and Windows 10 machines .... Installed OK and runs OK. But does not see the RevPi ...

I have just switched on our Revpi for the first time yesterday....
However I have a small problem

I have followed all your documentation on how to create a backup img
