Vitis 2024.1 Release

[Fatalon]

Hi is this repo here still active?
Do you have perhaps a version compatible with Vitis 2024.1 (which uses GCC 12.2.0)

None that I know, sorry. Ping @jasvinderkhurana in case you folks are working in this direction.

@Fatalon, As of today we don't have a version compatible with Vitis 2024.1, but we have plans to update it. I don't have concrete dates.. but we will work on updating KRS on ubuntu 24.04 and Vitis 2024.1 or above..

[Fatalon]

okay, thanks for your reply.
I am kind of working in that direction, but instead of full KRS I would already be happy if I can simply cross-compile ROS2 applications and run them on the Kria.
I experimented with your and the official Ubuntu image from Xilinx, but wasn't able to find a way to even get the host-code (OpenCL) compiled Xilinx Forum Post

So for this moment, I switched back to Petalinux which is supported by the new flow out-of-the-box and try to get the cross-compiling of ROS2 applications working there - if you have any tips regarding that, let me know

@Fatalon , can you provide some details on what example or application you are trying to compile? I can try to reproduce it at my end and then may be I can guide you well.

[Fatalon]

Thanks a lot!
Its the gaussian filter L2 example from the Vitis Vision Library with very gentle adjustments - which I later want to include into a custom Apriltag implementation.
But before I want to simply run both in parallel.
I know your KRS flow should be capable of realizing this as well but I wanted to use the new kernel object flow because it allows one to simply upload a new binary via dfx and not rebuild an sd-card every time.

Thanks for sharing the detail on the sample you are trying!

I have recently tried Vitis Vision library function on Ubuntu 22.04 with Vitis 2022.1 release and they work perfectly fine. I have to try with Vitis 2024.1 tools.

I want to understand if Vitis 2024.1 version is a must requirement for your development or can you fallback to Vitis 2022.1? If you can use the older version, I can give you a simple example which you can build Vitis vision functions with KRS and you don't need to flash the sd_card everytime.. you can just copy the bitstream and .xclibin for your new functions.

I am driving an Ubuntu 22.04 as my daily PC and I remember when I started a few months ago, XRT and/or Petalinux installer weren't working for Vitis 2022.1 anymore - because they were already listed in the archive I considered better to move on to the most modern release and put some time also learning the new Python CLI and scripting the whole flow.

If I can get the general flow to work with Ubuntu 22.04 in Vitis 2022.1 would be fine for me as well and I would be very keen on having a look on the example but only as a workaround as I think the new Python CLI is way easier to maintain/extend then the tcl scripts
