This document describes the instruction to run NVMe-IP demo with Angstrom Linux 2014.12 OS
on Arria10 SoC Development board. The demo is designed to get Identify data, write data, and
read data with NVMe SSD. User controls test operation through Serial Console. To run the demo,
FPGA configuration file as image file is prepared in microSD card. After that, install microSD card
to FPGA board for configuration after power on board.
1 Environment Requirement
To demo NVMe-IP Linux demo on IntelFPGA board, please prepare the following
hardware/software.
1) IntelFPGA board: Arria10 SoC Development board
2) PC with Serial console software, i.e. HyperTerminal
3) Power adapter of IntelFPGA board
4) NVMe SSD
5) 4 GB or bigger microSD card with demo image file, downloaded from
http://www.dgway.com/NVMe-IP_A_E.html
6) miniUSB cable for Serial communication
