fusesoc initialization error

[SaiRitish]

Hello ^^

So, I am trying to run microwatt on Arty a7. (final goal)

But I am not able to run "fusesoc init" for some reason

It says: usage: fusesoc [-h] [--version] [--cores-root CORES_ROOT] [--config CONFIG] [--monochrome] [--verbose] [--log-file LOG_FILE] {fetch,core,tool,list-cores,core-info,gen,list-paths,library,run} ... fusesoc: error: argument {fetch,core,tool,list-cores,core-info,gen,list-paths,library,run}: invalid choice: 'init' (choose from 'fetch', 'core', 'tool', 'list-cores', 'core-info', 'gen', 'list-paths', 'library', 'run')

And I was like: How can the command not exist, because it is documented at many places TwT

Could be a silly mistake that I have made, or something to do with the new fusesoc version? I'm not sure, but any help is appreciated. :)

@SaiRitish Hi.

init subcommand for fusesoc was removed since fusesoc 2.0. Now 'library add' is sufficient. So if you want to build microwatt, instead of this sequence:

$ source /opt/Xilinx/Vivado/2019.1/settings64.sh
$ pip3 install --user -U fusesoc
$ fusesoc init
$ fusesoc fetch uart16550
$ fusesoc library add microwatt /path/to/microwatt

Use this one:

$ source ~/Xilinx/Vivado/2024.1/settings64.sh
$ pip3 install --user -U fusesoc
$ fusesoc library add microwatt /home/gromero/git/microwatt/
$ fusesoc fetch uart16550

I tested it on Ubuntu 22.04 with Vivado 2024.1 webpack.

I'll send a patch updating the README.md, but feel free to test and submit the patch yourself.

Cheers.
