Could you try running the test with Verilator and show the output for that?
Just add .withAnnotations(Seq(VcsBackendAnnotation)) right after your cal to test(...).

It seems I did not install vcs. I suppose they are optional and I simply use the default simulator (maybe treadle).

Since vcs is commercial software, I use verilator instead. I add .withAnnotations(Seq(VerilatorBackendAnnotation)).

Strange.
I tried .withAnnotations(Seq(VerilatorBackendAnnotation)), it works. But the previous test without withAnnotation also works even after I remove Verilator. I can't reproduce the bug anymore.
Also, loadMemoryFromFile not work when using Verilator.

Sorry, I meant to suggest Verilator, got the annotations confused.

Also, loadMemoryFromFile not work when using Verilator.

How can you tell that it is not working?

Do you have a reproducible test that I should look at (i.e. a repo that I can download and a sequence of commands that I can run to see the same bug that you are seeing)? Or should we close this issue for now?

I have one commit you can take a look and I have a Github Action shows the log.

The problem no longer happens, I think we can close the issue.

OK. Let's close this for now. Feel free to re-open if you are bothered by the same issue again.
