I'm interested in debugging and profiling my artiq (kernel) code. There seem to be tools for that (artiq_coremgmt debug and artiq_coremgmt profile), but the documentation (https://m-labs.hk/artiq/manual/utilities.html#core-device-management-tool) of those seems a bit sparse, and I haven really been able to obtain much information by just running them as indicated in the documentation:
Running: artiq_coremgmt --device-db <path_to_device_db.py> debug allocator while operating the Sinara system in question doesn't output anything (on stdout or a file).
Running artiq_coremgmt --device-db <path_to_device_db.py> profile start and artiq_coremgmt --device-db <path_to_device_db.py> profile save profile.cgrnd <path_to_runtime.elf> exit both with an error:

artiq_coremgmt --device-db <path_to_device_db.py> profile stop returns nothing, which is expected, I guess.
Are there more resources on those utilities available somewhere? What's their intended use?
Thanks, and best regards!

Im running Artiq 5 on both the host and the Sinara system. The host system runs Ubuntu, Artiq is installed via nix.
