4.5 M.2
M.2 interface work on the NVME agreement
，
this sample use nvme2280 SSD hard disk of TOSHIBA RC100 for validation
purpose.
Hardware connection
Insert the SSD into J18 interface.
Software test
The Kernel has added the NVME protocol by default,so we can use SSD without configure any more.
Check the ssd is mounted by below command to check whether it mounted or not.
#df -h

Write and read SSD Write a hello strings to the test.txt on the SSD mount point, and then read it,compare with what bas been
written.
#cd /run/media/nvme0n1p1
#echo hello > test.txt
#cat test.txt
