The full blocks in the display are displayed by the firmwre.
It freeze here if the firmware cannot access the USB drive.
2 possiblities : you didn't t have the expected "/pfm2/" folder or your USB stick is not readable by the preenfm2.

Great! I've been reflowing the STM32F405 chip all night. Sight, at least is seems I didn't break it, cause I still have the blocks!
But great, my stick is 256MB, an old fellow! Ill try a couple others to see if that fixes the issue! Thanks!

Now I don't know what I'm talking about obviously, but: Would it make sense to have the screen say "Reading USB..." instead of just blocks at that point, so that it is obvious that the problem is USB related?

When i wrote this part of code i didn't expect the USB reading to fail with some USB stick.
But that's a good point ;)
