Note: To download binary of cm7 core into qspiflash and boot from qspiflash directly, following steps are needed:

Compile flash target of the project, and get the binaray file “hello_world.bin”.
Set the SW1: 1 off 2 off 3 on 4 off, then power on the board and connect USB cable to J11.
Drop the binaray into disk “RT1160-EVK” on PC.
Wait for the disk disappear and appear again which will take couple of seconds.
Reset the board by pressing SW3 or power off and on the board. (If default boot core is cm4, binary of cm4 could be downloaded and boot according to steps above.)
