Environment compatibility problems

[hleblevec]

Hello,
I am currently trying to run your project on my Alveo U250 board, but I am facing some issues. I noticed from trying to go through the notebook that the design needed xilinx-u250-xdma-201830.2 as shell on the board. However, after flashing this shell on the board using the last version of XRT and Ubuntu 20.04, the computer would not detect it anymore on the PCI port. I figured out it could be a compatibility problem so I tried using Ubuntu 18.04.5 instead. From this point, I am facing two issues:

• If I use XRT 2019.2, the board is detected my the lspci command, but not by the flash scan command from XRT, I therefore can't flash the bitstream onto the board.
• If I use XRT 2021.1, the board is found through flash scan, but isn't detected anymore anywhere after I put xilinx-u250-xdma-201830.2.

My request is the following: could you provide me the environment information you used for your project please? This would include your Linux kernel version (or distribution number) and the version of XRT you used.

Alternatively, could you point out to me what I would need to modify in your code to create a bitstream of the ResNet50 that would work with the last XDMA available?

Hoping you can help.
