I've started this documentation to record what's on (some of) my MicroSD cards. New MicroSD cards on top. New images on top.
Note: when writing MicroSD images via the USB adapter, especially on tact, first chown the device for your user and then use 'dd' from your own account, running 'dd' as root is way too risky, one wrong character and you can hose your operating system!
S4
2021-09-10-165338
This is a 32GB card that came with my Tomlov microscope. It is presently in the microscope.
S3
S3 is SanDisk 64GB Extreme Pro Micro SD Card, slated for use in the new Raspberry Pi 4B 'knowledge'.
2021-08-23-235713
I installed a configured 'knowledge' on this RPi today. I used the Ubuntu Server 20.04 LTS image from the RPi burning app on my MacBook Pro 'condor' to write the image, and then most of the config was done with salt stack.
S2
S2 is 16GB.

This image created below is invalid because I wrote the .xz file to the device not the .img file.

I checked the signature and I think the file downloaded okay...

S1 is 32GB.

This fixed the issue I was having because I was writing the .xz file to the device not the uncompressed .img file.

This didn't work because I wrote the .xz file to the device... :P
