The following input file does not exist: vadd.xclbin

[femust]

Hey,

so I am playing with the FPGA acceleration following this example and first I had a problem with

colcon build --build-base=build-kv260 --install-base=install-kv260 --merge-install --mixin kv260 --packages-select ament_vitis ros2acceleration offloaded_doublevadd_publisher

[0.188s] colcon.colcon_core.verb WARNING Some selected packages are already built in one or more underlay workspaces:

    'ros2acceleration' is in: /home/andrzej/code_workspace/krs_ws/install
    'offloaded_doublevadd_publisher' is in: /home/andrzej/code_workspace/krs_ws/install
If a package in a merged underlay workspace is overridden and it installs headers, then all packages in the overlay must sort their include directories by workspace order. Failure to do so may result in build failures or undefined behavior at run time.
If the overridden package is used by another package in any underlay, then the overriding package in the overlay must be API and ABI compatible or undefined behavior at run time may occur.

If you understand the risks and want to override a package anyways, add the following to the command line:
    --allow-overriding ament_vitis offloaded_doublevadd_publisher ros2acceleration

This may be promoted to an error in a future release of colcon-core.

so there is lack of *.cmake files, but I figured that in order to solve this problem I can just add vitils_common

colcon build --build-base=build-kv260 --install-base=install-kv260 --merge-install --mixin kv260 --packages-select ament_vitis ros2acceleration offloaded_doublevadd_publisher vitis_common

everything compiles, despite that the following error shows up

ERROR: The following input file does not exist: /home/andrzej/code_workspace/krs_ws/build-kv260/offloaded_doublevadd_publisher/vadd.xclbin

Then when I run on kv260

ros2 run offloaded_doublevadd_publisher offloaded_doublevadd_publisher

the following error appears

INFO: Found Xilinx Platform
ERROR: vadd.xclbin xclbin not available please build

any hints on where this error is coming from or from where the file vadd.xclbin is coming from?

This ugly warning is being treated at https://github.com/colcon/colcon-core/issues/469, awaiting for Open Robotics.

You are missing vitis_common in your ROS 2 workspace. There's currently no documentation for HAWG packages. The best resource is KRS's alpha documentation if you want to get it working.

Did you follow the installation process appropriately https://xilinx.github.io/KRS/sphinx/build/html/docs/install.html, you'll see that package should be fetched and I can see vitis_common listed as a build dependency, so AFAIK, it should work.

colcon build --build-base=build-kv260 --install-base=install-kv260 --merge-install --mixin kv260 --packages-select ament_vitis ros2acceleration offloaded_doublevadd_publisher vitis_common

everything compiles, despite that the following error shows up

ERROR: The following input file does not exist: /home/andrzej/code_workspace/krs_ws/build-kv260/offloaded_doublevadd_publisher/vadd.xclbin

Well, it sounds like you might not be building the kernel successfully. Can you list /home/andrzej/code_workspace/krs_ws/build-kv260/offloaded_doublevadd_publisher/ for us in here? Can you also inspect the log files from vitis (which should be at that directory) at let us know if there's been any issues while 1) synthesizing or 2) place&routing the kernel?

Make sure you use Vitis 2020.2.2, KRS alpha has only been tested with that.

[femust]

Hey @vmayoral,

the first comments are understandable but I added them for completeness, I use also Vitis 2020.2.2

What's xck26-sfvc784-2LV-c ?

[vmayoral]

Oh! I see what's the issue 👍! Thanks for posting all of that.

xck26-sfvc784-2LV-c is the part number used by the KV260 board which was not included by default in Vitis 2020.2.2 and required manual configuration to build kernels against that part. I'm sorry you experienced this hurdle. Unfortunately, there's little I can do about to prevent things like these since I'm not involved in Vitis releases.

I documented this issue a while ago at https://xilinx.github.io/KRS/sphinx/build/html/docs/howto.html#how-do-i-handle-board-part-definition-was-not-found-type-of-issues. Let me know if that works for you.

(I'm being told that newer (which are now archived 🤣) ) versions of 2020.2.2 do include it)

[vmayoral]

@femust did you address your issue?

[femust]

@vmayoral I should be able to get back to you with feedback this week/weekend whether it works (for the time being extremely busy, unfortunately)

[vmayoral]

Closing this for now.
