Reverse engineering the FRC systemcore image

FIRST announced the systemcore several months ago now and the beta software started rolling out recently and becoming way more polished so with the release of the new driver station I decided it was time to dig into the firmware image and see what I could find! they really did a great job of making it look nice and polished The systemcore is based on an Raspberry Pi Compute Module 5 and as a result the image is just a zipped .img file that extracts to 10 GB in size (the size of the emmc) but considering that the original zip file is only 1.8 GB there is likely quite a bit of empty / wasted space. It is interesting that they didn’t choose to go the auto expanding route but I’m guessing they did this for ease of use.
