NOR Flash SPI with FatFs and USB Mass Storage Example on SAM4S Xplained in Microchip Studio 7

Описание к видео NOR Flash SPI with FatFs and USB Mass Storage Example on SAM4S Xplained in Microchip Studio 7

// Watch out for phone jumpscare at 10:48 //

In this video:
using a SPI NOR Flash as FatFs disc by changing Virtual memory access,
using USB MSC for disc access by the computer,
setting the SAM4S Xplained board to work with the NOR Flash.

The memory I used is Winbond W25Q128FV.
Before making fat format on a new flash / used but no fatfs make sure to run full chip erase. Then on the computer use FAT format with 4096bytes allocation unit.

Make sure not to break any ongoing write to NOR Flash by reseting or powering down the microcontroller because it causes to make the FAT file table corrupt. In this example it is safe to unplug the usb power only when both LEDS are OFF!!!
