Spike failed to execute test examples

[Damien Towning]

I have successfully compiled the examples under Chipyard/tests and have also successfully compiled the hello.c given in the baremetal documentation given here : https://chipyard.readthedocs.io/en/latest/Software/Baremetal.html.

However I must be missing an environment variable or something because when I give the compiled test examples to spike I get the following.

Run accum..
*** FAILED *** (tohost = 2)
Run big-blkdev..
*** FAILED *** (tohost = 5)

Run streaming..

*** FAILED *** (tohost = 7)
Run streaming-passthrough..

Do I need to start some sort of server or set other environment variables in env.sh before starting spike? Everything compiles fine. No errors.

Most of those tests test some peripheral device which spike does not model, hence the various errors.

Ah thank you. That makes sense.

Couple more questions before I go hit the docs. 

- Can I at some point going down the spike path get my work out as Verilog?

- Can I define either a basic UART or some sort of GPIO for Spike and bind that to the host as a dev ? 

Thanks ! 

[Damien Towning]

After several days of tinkering with Spike I now want to ask what is the correct way to execute those test examples? I cannot seem to find it documented anywhere. 

[Jerry Zhao]

You have to build the corresponding SoC that supports whatever peripheral/accelerator that test is targeting, and run the binary on the RTL simulator of that SoC.
RocketConfigs.scala lists a bunch of SoCs, some of those probably correspond to the C tests.
