Viavdo - Zynq7000(Linux - Ubuntu) - PL

angerpro

Hi guys, I am in a project that I need to boot Linux OS to ARM a9 in Zynq7000(Zedboard). Before my way to design FPGA is Vivado -> .XSA file -> Download XSA file in Vitis -> use Vitis to manage PS and control data path, get result and etc.
Now instead of using Vitis, is there any way that I use Vivado to create block design -> export hardware(include bitstream) .XSA file -> send it to Linux - particularly Ubuntu (inside ARM core a9) ->  then use it to implementation PL? and after that I can use directly Linux os to control the peripherals as Leds, Switches, vga??? I saw some tutorials that uses Petalinux, my opinion is that Petalinux is convinient but heaveweight. If I can not use OS like Ubuntu, even simpler Debian, then last choice I will use Petalinux.

Thansk for reading my question. And also my English is not really good, sorry if there are obscure questions.

    Hi angerpro,

    First of all, petalinux is really lightweight, it is designed to be able to run in very feeble SoCs such as Zynq7000. I don't think that you could install Ubuntu on your device since it is a 32 bit system.

    Building petalinux is not trivial, and once you have it, since you would have used an XSA file to build it, you will have the hardware instantiating in the PL since boot up. I do not know if you also want to be able to swap between hardware designs... I've been able to do this (though not thoroughly tested it) via changing the XSA in the petalinux project, recreating the hardware outputs and changing only the ones from the fat32 partition on the SD. The other option is "fpga manager" option. I would let the latter for last.
