Firstly, to download the files from the git repository, you need to install git. The prompt will ask your user password. $ sudo yum install git If this command works the terminal will ask you whether you want to install this package. Is this ok [y/d/N]: Type yes to confirm you want to install git.

You can download all the source files project. $ git clone git@github.com:Yarr/Yarr-fw.git Check whether the files were downloaded, by listing the folder. You should see a folder named "Yarr-fw".

Move in the folder where you will generate the bitfile. $ cd Yarr-fw/syn/xpressk7/ddr3_revA/ To launch the synthesis you just need to launch make. $ make Prepare a coffee, it will last around 15 minutes to synthesize all the project.

Move in the folder where the script file are. $ cd Yarr-fw/script/ Launch the script for flashing the memory. At this point you can choose the bitfile by pressing the belonging number. If there is only bitfile you need to press 'y'.

$ python flash.py
Several bit files found: 
0: /home/***/Yarr-fw/syn/xpressk7/ddr3_revA/yarr.runs/impl_1/top_level.bit
1: /home/***/Yarr-fw/syn/xpressk7/bram_revA/yarr.runs/impl_1/top_level.bit

The terminal will ask you if you want to flash the flash memory or the RAM. As you want a persistent system, press F for Flash. Will you flash the RAM or the Flash [R/F] ? Then shut down the computer. After the next boot firmware is ready to use. $ systemctl poweroff

Note: A soft reboot is not enough to get the system working.
