xbutil examine: no devices present

[hoosierEE]

I'm trying to set up a U250 in a workstation for the first time, and got to this issue. It seems like there is no device found by xbutil examine, but based on the troubleshooting docs it seems like my card is in fact recognized (by both lspci and Vivado's hardware manager). According to this doc the next step seems to be to "revert the card back to the golden image", but this is a brand-new card that's never been programmed by me. Is "revert" necessary?

Running lspci looks like the card is found, but conspicuously absent are kernel drivers:

My Vivado hardware manager is able to find the U250.

I'm using Vitis 2022.2 on Ubuntu 2022.04.2 LTS.

@hoosierEE , it is not clear, but it is showing driver is not there. Was XRT installed correctly?

By the way, if you go to the Xilinx community forum or Alveo Forum for these type of issues, there you can probably get other similar questions/answers or quicker support.

Maybe you also want to review the tested operating system and try there

Thanks for the response. I am using Ubuntu 22.04 LTS and the .deb file I downloaded from Xilinx (following the prompts to get the right version) is xrt_202220.2.14.354_22.04-amd64-xrt.deb, which I assume is XRT 2022.2, which is one of the "tested" combinations from here: https://support.xilinx.com/s/article/000034458?language=en_US.

When I follow the install instructions (from here: https://xilinx.github.io/XRT/master/html/install.html), there is no indication of any error:

sudo apt install ./xrt_202220.2.14.354_22.04-amd64-xrt.deb

Note, selecting 'xrt' instead of './xrt_202220.2.14.354_22.04-amd64-xrt.deb'
xrt is already the newest version (2.14.354).

Since I did this step already, it now just says "xrt is already the newest version". apt info says this about the xrt package:

U250 installation has few steps, such as installing various package (satellite controller package, cmc package, base package, shell package, validate package, etc).. It requires to program the card and cold reboot. I suggest getting help from Alveo forum, as they are expert in card bringup support

[hoosierEE]

Thanks again. It seems likely that I did not install XRT properly. A local colleague is helping me currently but if that fails I'll ask on the Alveo forum.
