# The freertos component provides the `start_app` and `start_app_other_cores`
# if it is included in the build. It then calls `app_main`
# from the main task created, which must be provided by the user.
# Like for `start_app` and `start_app_other_cores`,
# we can't establish dependency on what we don't yet know, so we force the
# linker to not drop this symbol.
