I just reciedv two 32Gb UUgear eMMC keys and two new Raspberry Pi Zero 2 w's

I expected to be be able to insert the eMMC and just boot.

The first boot succeeds to desktop OK 
Then when I set wifi OK
df -h tells me I have zero space. 

When I attempt to sudo apt upgrade I get no space on device. 

Next reboot fails.

Just '-' top left

Same thing happened with both Pi's and with both eMMC's. 

What did I do wrong! 😉

Please read this post first:

Should be the same problem.

Yes that doeslook familiar, apologies, I did not see that in the doc I followed when booting. 

Of course now (as I mentioned) booting is failing, so I can't get to a shell to use 'sudo rapsi-config' 

Any suggestions for getting back to being able to boot?

Trying to upgrade the system without success would not damage the system or the hardware.

You may try pulling it out and inserting it back to the SD card slot, and see if that helps.

If your RasPiKey can be recognized after inserting to an SD card reader, you can also flash the OS into it by yourself, just like flashing a normal SD card.

For anyone else in this situation. 

Reinserting RasPiKey did not help. 

Mac would not read the RasPiKey when I inserted into SD card reader.  


I installed rpi-imager on mac
I used rpi-imager on mac to write any old  'traditional' image on an SD card  
Booted pi zero with that SD card
Installed rpi-imager on pi
pulled the image for RaspiKey from (BTW curl complained that the certificate was out of date so need to use --insecure)
wrote this image to eMMC
Booted with RasPiKey
Then expanded FS via sudo raspi-config
Rebooted and Voila.... I have 32G to play with (well 24G)

Thanks for your help
