Understanding the project tree and using EMIO GPIO

[ghost]

Hello,

I would like to use EMIO GPIO. Where does one begin when opening the project in Vivado (I am using 2016.2)?

Thanks.

Sorry, I don't understand your question.

I am trying to create some more GPIO pins and I would like to do this via the EMIO. I want to send this GPIO output to the other Red Pitaya header. I then want to access these new GPIO pins from the Linux kernel (I would need to update the Device Tree).

What I need to know (as the starting point) is where the RedPitaya Vivado project lives so that I can create the new GPIO lines.

Thanks for more details.

Here are the commands to create and to open a project:

git clone https://github.com/pavel-demin/red-pitaya-notes
cd red-pitaya-notes
make NAME=led_blinker xpr
vivado tmp/led_blinker.xpr
