"ipbb ipbus gendecoders" does not work

[abunickabhi]

While setting up a firmware project, I follow the instructions listed https://serenity.web.cern.ch/serenity/emp-fwk/walkthroughs/walkthrough1.html#walkthrough1 here.

I am unable to ipbb ipbus gendecoders as it does not recognize ipbus as a valid keyword.

How do I execute this command successfully? What does this command do exactly?

Hi,

Can you paste the output of the command here?

Thanks,
Tom

Hi,
Here is the output when I execute the command in ipbb environment.

(ipbb) (base) abhi@abhi:~/Desktop/CMS_Trigger_TIFR/ipbb/algo-work/proj/my_algo$ ipbb ipbus gendecoders
Usage: ipbb [OPTIONS] COMMAND [ARGS]...
Try 'ipbb -h' for help.

Error: No such command 'ipbus'.

Edit: I have installed ipbus firmware and added the /opt/cactus path.

What could be the issue for not recognising the ipbus keyword @tswilliams ?

[tswilliams]

I'm not completely sure what the cause of this could be. What operating system are you using? Could you try skipping that command, and running the ipbb vivado commands listed after that?

[abunickabhi]

I am using Ubuntu 20.04.

Skipping the command is working as I am able to create a bitstream using ipbb vivado.

Is the ipbus gendecoders command optional while making a bitstream project for Serenity?

[tswilliams]

Yeah, as long as you don't need to add address decoding in the payload (and this is the case for most payloads right now), you don't need to run the gendecoders command

Got it thanks!
