Embedded-Linux-Tutorial-Zybo

Hi,

I came across this tutorial that  @Commanderfranz created for the Zybo https://www.instructables.com/id/Embedded-Linux-Tutorial-Zybo/.  It is also referenced here:  https://blog.digilentinc.com/zybo-embedded-linux-hands-on-tutorial/, which also includes the "Embedded Linux Tutorial for the Zedboard".  As far as I can tell the Embedded Linux Tutorial for the Zedboard uses the Xilinx ISE instead of Vivado.  What differences will there be to follow the "Embedded Linux Tutorial for the Zedboard" tutorial in Vivado?

Likewise, what differences will I have to make if I follow the https://www.instructables.com/id/Embedded-Linux-Tutorial-Zybo/ on the Zedboard?  My initial skimming of the tutorial makes me think that the most obvious thing will be changing the constraints to match the Zedboard for the custom LED IP that is being created.  The only other thing that I see that would need to be changed is creating the base system.  The base Zybo system looks like a simple Zynq IP with a few GPIO modules to support the LEDS, switches and buttons.  Is there anything else that I would need to include for it?  Or perhaps is there a better/bigger image of what the Zybo base system looks like?

 

Thanks,

Stuart

Hi @studogger,

I do not have enough embedded linux experience to alter the tutorial to use Vivado. Petalinux has become the Digilent's supported embedded linux platform for the last few years. Petalinux is basically a wrapper for yocto. Here is an instructable for either the zybo or zedboard using Petalinux. The Petalinux Support for Digilent Boards has multiple petalinux project versions available for the Zybo. The readmes are very informative and have a quick start guide as well.

thank you,

Jon

Hi @jpeyron

Thanks for the links.  For the Petalinux support for Digilent boards, I don't see a version specifically for the Zedboard, unless it's being called by a name I don't recognize.  Do you know if there is a board file that most closely matches it?

 

Thanks,

Hi @studogger,

We do not have a petalinux project for the Zedboard. One of our collaborators Avnet has some good petalinux information and projects at Zedboard.org. Here is one of their projects. This project links to this tutorial here that should be helpful as well.

cheers,

Jon
