This is an USB Host Mass Storage and File System example.

After the USB Flash memory stick is connected it creates/overwrites 
a file with name "Test.txt" and content "USB Host Mass Storage!".

Board:                  NXP 'EVK-MIMXRT1060' ('MIMXRT1060-EVK')
Microcontroller:        NXP MIMXRT1062DVL6A
Clock Settings:         XTAL =  24 MHz
                        CPU  = 600 MHz
USB:                    OTG1 (connector J9)
                        OTG2 (connector J10)
User Interface:         none

Notes:
 - In case of debugging problems consult the documentation and Blinky example
 - Power the board with external power through J2 barrel connector with 
   stable 5V voltage (center +), jumper J1 short 1-2, switch SW1 position 2-3
