[FAQ] PROCESSOR-SDK-J721E: nvme initialization and sdk commands

Part Number: PROCESSOR-SDK-J721E

This is more of  an fyi if you want to connect an NVME SSD drive to the J721 EVM.

The drive i bought is

once you get the drive the connector for the NVMe is on the back of the J721 evm. Once you connect the drive to the J721 board, then use SDK 7.3 to boot the board.

Once you get the linux prompt make sure that you have the nvme in your /dev directory. below is what it should look like

ls /dev/nvm*
/dev/nvme0 /dev/nvme0n1

if yes then it is all set but you just need to format it so you can use it. below are the commands to format the drive and mount it

root@j7-evm:/# mkfs.ext4 /dev/nvme0n1

root@j7-evm:/# mount /dev/nvme0n1 /home/root/test/

Also in the sdk it talks about the lspci -vv, this command is not in the /bin but you need to run it as  /usr/sbin/lspci -vv  then it will work as defined in the sdk docs.

i hope this helps you to install the nvme ssd drive.
