Restore default Debian system

[bcnaz]

I ordered the usb to emmc adaptor, but I know it will take a while to come down.

You can get one from Amazon in just a coyote of days for 10 bucks

I am in the UK, and on Amazon UK I couldn't find one for a reasonable price. I ordered it now anyway.

What I would like to work out is why I am unable to boot from sd, as it should work really.

   @uby89 :

  I 'Think' reflashing your eMMC with thhe usb adapter will get you going.

However the on chip boot order is SPI NOR, then eMMC, then SD, then USB OTG.

Boot Order via a working OEM Mate/Debian eMMC is :  SD card then eMMC
 
But that is just the "Order" it tries to boot.

If you dig around on this forum you can solve almost any problem, BUT if you are like me,  you look for the simplest way to do that.

Me :  I would try reflashing your SD card using etcher, if that does not work.... Hope the usb adapter arrives quickly  !
