[MinnowBoard] Firmware hang

Be aware that SPI flash has limited life cycle. If we repeatedly erase it (like write big variable into it), the SPI chip will be dead very soon. Then it will look like variable corrupted.

I had a similar problem on a minnowboard max. I ended up replacing the SPI flash part on it and that solved the problem. Of course I probably caused the problem by repeatedly programming the SPI flash with a 5v programmer while I was working on UEFI driver development. I don't remember specifically where the boot would hang but repeated power cycling the board would get it too boot eventually. The problem started out happening occasionally and slowly got worse until I had to power cycle many times to get a good boot.
I used part # N25Q064A11ESE40G as the replacement. Here is a link to Arrow where I purchased them.
Hope this helps.
