Bjoern Firmware Install

I have the same issues with firmware updates. I think the main trick is to rename the file to something less than 4 characters. I also do not get the .CUR extension either.

As for my freezing issue, I am now working okay with a more modern microsd with sd adapter as well. So far so good anyway. Hopefully it stays this way because I really don’t want to diagnose sd reader issues or buy a new board.
