I know that. It’s me, eric25. I’ve been following this thread since you started it. Now, back to my point. The 2MB flash chip shows up through the same hardware channel in windows as my SD card does, the STM32 USB controller, meaning it’s using the same channels as my SD Card slot. My SD card can only be read in BenF when I use that formatter utility. If I format it through the Nano itself, using a USB cable, or by taking the card out and using a separate card reader, it still works the same way. If your flash chip is on the same channel, BenF should call it the same way, and the formatter utility should prep it the same way.
Just try it and stop assuming I don’t know what you’re talking about. The way it’s addressed, it shouldn’t be able to do any damage, at least.

P.S. Totally didn’t want that to sound flamey, just trying to say you’ve been very detailed in your descriptions, I’d have to be an absolute idiot to think you had an SDcard slot at this point…
