66st Will Not Boot

[CheminerWill]

I seem to have resolved this but it was concerning and I think it may have happened once before several months ago. So, I am posting just so any future searchers of this board with the issue might find what I had to do to fix.

My 66 would start to boot then just shut down before competing. Tried several times and it happened every time. I took out the SD card and sure enough, it booted. Put the card back in and no go. I could read the card fine on my computer so I tried deleting the GGZ file thinking maybe a record was corrupt, but that did not fix either. I saved any custom files like my custom symbols and then reformatted the card. Put the reformatted card back in and all is fine now. I will have to recreate the directory structure on the card I guess, but so far I have only a new GGZ folder with GGZ file and the custom symbols folder with symbols on the card and both of those are working fine.

I had the same bug with a BC-map on uSD
Removing uSD and booting was fine

I finally deleted the BC.img
