Good one @mohammedrafi-sk. This error happens because /home/mr/krs_ws/install-kr260-ubuntu/../acceleration/firmware/select/SOC doesn't exist in your development machine and is generally caused by the fact that you have not "selected" the embedded/SOC target which you can do as follows:

# for the KV260 
colcon acceleration select kv260

# or for the KR260 
colcon acceleration select kr260

Technically, this is documented in the examples (e.g. this one) however, with the recent changes in documentations (e.g. with Ubuntu's enablement) I agree this deserves further attention. Maybe a small PR simply adding this command would be helpful @mohammedrafi-sk?

Having said that all the above, ⚠️ please see workaround in here as discussed previously ⚠️, note the limitations explained there about the current firmware. Following those steps will simplify your life. Feel free to contribute with PRs based on your experiences please.

I'm also running into this issue building for KR260.

It's not clear to me how to fix this. Also documentation about where and how things need to be run as root for Ubuntu 22.04 need serious work.

I've had issues installing this in a VM so I go to baremetal and it doesn't fix it. I run everything from source onward as sudo -s to get anything to build. But now after rebuilding like 6 times and nothing is fixing this build error and setting the acceleration does noting at all for kr260. The guide says it should prompt for sudo password it never does as a normal user.

The point of an install guide is that you should be able to run the commands to install the tools without any ambiguity but the entirety of the KRS for cross-compilation and Xilinx tools installation in general are ambiguous.

"Oh just install 2022.1" but actually you need to install some Ubuntu 22.04 packages before it will install because it will get to the very end of the 66gb download and make you reinstall it again and it re-downloads everything...

There needs to be some real documentation on how to setup the environment beyond a single line blurb and the constant assumptions made in the install guide.
