Node-locked license issues with Docker

[vittorioserra]

Hello everyone. I have a ZCU102 and I am trying to run the end2end examples. I am able to synthesize the code for the PYNQ devices, but when i try to do the same for the ZCU-102 I get the following error : Synthesis failed, no bitfile found. Check logs under /tmp/finn_dev_name/vivado_zynq_proj__gr37nr1

I have looked in the logfiles (and single-module sub-logfiles) produced and it looks like the feature "Synthesis" for the ZCU102 MPSoC is not available. The error there is the following :

Starting synth_design Attempting to get a license for feature 'Synthesis' and/or device 'xczu9eg' WARNING: [Common 17-348] Failed to get the license for feature 'Synthesis' and/or device 'xczu9eg'.

Please confirm with your license admin that the correct version of the license server tools are installed. INFO: [Common 17-206] Exiting Vivado at Thu Mar 10 09:29:23 2022...

All the sub-logfiles state the same error.

As far as I can tell from using the combination of ZCU102 and Vivado/Vitis HLS I am able to synthesize and deploy to the device.
I have checked which licenses are installed on my machine, there is no feature called 'Synthesis' but all the other licenses seem to be ok.

Sorry for the beginner question here and thanks in advance for the answer.

Hi, the ZCU102 is not covered by the free WebPack license. Since FINN runs Vivado from within the Docker container, you'll need to pass your license information (e.g. a file or path to a license server) to this container. See https://finn.readthedocs.io/en/latest/getting_started.html#vivado-vitis-license

It is locked to the MAC address of my PC's eth0 interface. We were able to find a solution to the problem.

It is necessary to give the same Host-ID to the docker container too, hence the MAC-Address of the docker container needs to be set. To do it, modify the docker run call in run-docker.sh by adding the same MAC-address as the Host-ID's to the command.

The line will look something like this : DOCKER_EXEC="docker run -t --rm $DOCKER_INTERACTIVE --tty --init --mac-address <Host-ID-MAC-Address> "

Another solution, which would be more advantageous in order to connect to the board in later steps, would be to add --network=hostin the DOCKER_EXECcommand

Makes sense, thanks for posting your solution! I'll mark this discussion as answered and we might add these instructions to our "Getting Started" guide.

I tried adding --network=host and it's not working. Any suggestions, please?

One can also try to copy the node-locked license file inside docker ("/tmp/home_dir/.Xilinx"). That worked for me.
