When running fusesoc run --target=ulx3s servant for the for the ULX3S, I see this error:

But note the icebreaker, with a PCF

I also tried the blinky directories that contained the ulx3s files, but all with the same error:

fusesoc run --target=ulx3s servant

fusesoc run --target=tinyfpga_bx servant
fusesoc run --target=ulx3s servant

Of course, I'm left wondering about the WARNING: The CAPI1 core file description format is deprecated and will be removed in the next major version of FuseSoC. Please port your core files to the CAPI2 format..

Greetings @gojimmypi !
Take a look at these lines in servant.core.

serv/servant.core

Lines 356 to 366 in 28953fe

	ulx3s_85:
	default_tool: diamond
	description : ULX3S 85k version
	filesets : [mem_files, soc, ulx3s]
	parameters : [memfile, memsize]
	tools:
	diamond:
	part : LFE5U-85F-6BG381C
	trellis:
	nextpnr_options : [--package, CABGA381, --85k]
	toplevel: servant_ecp5

1. You are targeting the fileset through the command.Rewrite the command as fusesoc run --target=ulx3s_85 servant
2. Make sure you have "diamond" installed in order to use this target.

Hope it resolves your issue.

[gojimmypi]

Hello @KinzaQamar and thank you for your suggestions!

TL;DR: it works! :)

my servant.core is located in fusesoc_libraries/serv from the above-mentioned project directory initialization.

sure enough, I was only looking at the filesets section. I found the targets you mentioned, and tada! That's Where diamond is found.

I understood the error, but did not realize that's where to edit it.

As a suggestion to @olofk perhaps it would be a good idea to write something to the console:

Using tool from fusesoc_libraries/serv/servant.core: diamond; see section targets:ulx3s_85

I see that trellis is another option defined for the ulx3s_85 but when I try to specify that with --tool=trellis I still get the same error:

0 $  fusesoc run --tool=trellis --target=ulx3s servant
WARNING: The CAPI1 core file description format is deprecated and will be removed in the next major version of FuseSoC. Please port your core files to the CAPI2 format.
ERROR: Failed to determine work root. Could not resolve target

And so here, the fact that I am still targeting the filesets section, and they keyword ulx3s was found but not in the desired targets section, perhaps a more intuitive error would be good here?

WARNING: Found filesets=ulx3s but did you mean to specify a targets=[value] in your fusesoc_libraries/serv/servant.core?

Further, note that my servant.core contains CAPI=2: at the top, contrary to the CAPI1 warning.

I thought perhaps I could just change my default like this:

  ulx3s_85:
    default_tool: trellis
    description : ULX3S 85k version
    filesets : [mem_files, soc, ulx3s]
    parameters : [memfile, memsize]
    tools:
      diamond:
        part : LFE5U-85F-6BG381C
      trellis:
        nextpnr_options : [--package, CABGA381, --85k]
    toplevel: servant_ecp5

but I still saw the same error:

0 $  fusesoc run --target=ulx3s servant
WARNING: The CAPI1 core file description format is deprecated and will be removed in the next major version of FuseSoC. Please port your core files to the CAPI2 format.
ERROR: No tool was supplied on command line or found in 'servant' core description

(again, I didn't realize they keyword section problem of filesets vs targets)

Perhaps something as simple as:

Error: keyword ulx3s not defined in targets in ./fusesoc_libraries/serv/servant.core

Anyhow, it WORKS! 👍

Changing the default as shown above, and I am able to build for the ULX3S:

fusesoc run --target=ulx3s_85 servant

Curiously, even when specifying the --target=ulx3s_85 I was not able to specify the --tool=trellis like this:

0 $  fusesoc run --target=ulx3s_85 servant --tool=trellis
WARNING: The CAPI1 core file description format is deprecated and will be removed in the next major version of FuseSoC. Please port your core files to the CAPI2 format.

fusesoc run servant_1.1.0: error: unrecognized arguments: --tool=trellis

It is apparently order-dependent, as this works:

fusesoc run --tool=trellis --target=ulx3s_85 servant

I undid my changes to the file and sure enough, I was still able to build for the ULX3S!! Woohoo!!

Thanks so much for your help! Cheers.
