gem5 simulation hang #3

Open proppy opened 5 months ago

proppy commented 5 months ago

when following README instructions to drive the simulation with gem5: https://github.com/antmicro/xls-cosimulation-demonstrator?tab=readme-ov-file#run-gem5 it currently hangs on:

This is what you are supposed to see when the simulation starts.

If the run is successful, then you will see output with the following lines:

system.platform.terminal: Listening for connections on port 3456

Followed by simulation started prompt:

system.remote_gdb: Listening for connections on port 7000
Starting simulation
src/sim/simulate.cc:194: info: Entering event queue @ 0.  Starting simulation...

I see all of the those in your output. It looks like the simulation has started.

Have you tried proceeding further with README, by that I mean connecting to the terminal on port 3456?
