Tofino Example: no bf_swithcd for one of the switches

[Excel3884]

Hello everyone,
I have been trying to run the tofino example (https://github.com/nsg-ethz/p4-utils/tree/master/examples/tofino). Although, every time I set up the network, I can run run_bfshell.sh for only one of the switches (either s1 or s2). It looks like that bf_switchd is not running at all on the specific switch.


Is it possible that happens because of the fact that BF Runtime Server is using the same port (50051) every time it's being started?
SDE Version: 9.11.0
Thank you in advance.

I realized that the example was working on Ubuntu 22.04, but not on my current distro (Ubuntu 18.04 minimal). The problem was solved by installing GDB.

How did installing GDB fix the issue? Any idea? Is it a dependency?

Hello,
Unfortunately not. Once I installed GDB, I ran the second switchd using the -g flag to find out what's wrong (manually without running the example's code). Although, I doubt that this solved the issue, as I could run more switchds later without the flag. I guess it's probably a dependency like you said.
