Petalinux 2020.1 - Minized

Question

Hello! I just have started testing new scripts for Minized 2020.1 version ( https://github.com/Avnet/petalinux/tree/2020.1 ) First thing to say "WOW!" I'm amazed by new scripts and how they work, even the documentation is there with different boot methods It was a great idea to rework git like that, it will be so much easier for new developers to start having fun with zed family. Also, I have a question.... As these project should be your starting point to develop things on your own, I have tried to add openCV library, but building petalinux failed. It is some problem with wic image. "petalinux-build" I could just remove wic image from packaging option, but I would like to use it like in "how_to_boot.txt" It is some problem with building command? Tips will be appreciated Little suggestion this: "petalinux-build -c avnet-image-minimal" "petalinux-build -c avnet-image-full" should be added to "how_to_boot.txt" If someone is using only ready scripts they could get stuck building empty project with old commands Also is this possible, to add QEMU arguemnts and BIF files for Vitis? That would be great! What do you think about adding different boot methods as scripts for Minized minimal image or jtag boot? Imagine that you could just do: "xsdb boot_jtag_INITRD_MINIMAL.tcl" and ./boot4method.sh or something like that even better "xsdb boot_jtag_INITRD_MINIMAL_boot4.tcl" full automatic tcl that reprograms and reboot system (that could be a bit overkill) Message was edited by: Bartosz Rycko

Hi there,

Thank you for the feedback! We do work very hard to try to enable our customers and constructive criticism is heard by us. We take it seriously as ... well frankly, I am not you. I can only guess as to what is the best way that I would want "this" to work.

We have not made official tags yet, so the 2020.1 repo is still in fluctuation. We have seen the "WIC issue" and have a workaround at this time. We are working towards a proper solution.

For now, you can work around that using:
petalinux-build -c avnet-image-minimal

In our internal review, we also found the issue:

"

Little suggestion this:

"petalinux-build -c avnet-image-minimal"
"petalinux-build -c avnet-image-full"

should be added to "how_to_boot.txt""

Thank you for confirming that it will be very important to the success of this flow!

Can you explain more about your QEMU need? I added that into the Vitis flow in 2019.2 and had users using that. I think it should be working and OK? Unfortunately, MiniZed did not get a Vitis platform for 2019.2, so there could be a problem with that platform. You should be able to leverage those changes in the Vitis make scripting and use QEMU with Vitis now?

I will bring your feedback about the different boot methods back to the team. Please note that for every boot method it increases the permutations for testing significantly, so that is usually a bit more difficult to support. However, as I said, we certainly take feedback seriously.
