nic-loopback test fails in Chipyard 1.10.0

[Sabra Ossen]

Hi All,

I've been using the nic-loopback test as a sanity check for a working baremetal NIC.

This test works as expected and provides the correct output in Chipyard 1.9.0 with the following output.

Trial 0
send/recv 7221 cycles
Trial 1
send/recv 5513 cycles
Trial 2
send/recv 5016 cycles
All correct

However, fails in Chipyard 1.10.0, and is stuck at

Trial 0

We're using FireSim 1.17.0 and AFAIU we need to use Chipyard 1.10.0 for compatibility.

Is there another recommended approach for testing the behavior of the NIC or can we use Chipyard 1.9.0 with FireSim 1.17.0?

Hi,

In the 1.10.0 release, the NIC loopback config in chipyard has a clock domain bug.
I believe it is fixed in 1.11.0

Best,
Joonho

Can the clock domain bug be patched in 1.10.0 or when I upgrade to 1.11.0 would I also have to upgrade FireSim to 1.18.0 (is it officially released? the docs are still on 1.17.1)?

I've been identifying compatible versions by checking the Chipyard commit in the FireSim repo. (https://github.com/firesim/firesim/tree/1.18.0/target-design)

Thanks,

Sabra

You can patch it..

Personally, I recommend switching to the latest version of chipyard and firesim on the main branches of each.
We have not had time to push a release recently, but these should be stable, and it is easier for us to immediately push bug fixes into main, instead of backporting.

I've been identifying compatible versions by checking the Chipyard commit associated with a FireSim tag (https://github.com/firesim/firesim/tree/1.18.0/target-design).
