I will push commits to a fork of the rtems. Have given a link to the
repository in the readme.md of the Tracing repo. Will that be okay?

runs on the RTEMS target and what runs on the development host.
Done
Ok, thanks, but why did you remove the RTEMS application? This is the
first step. The repository should contain a sample application with a
Makefile (or waf or whatever, but no manual steps) to generate a sample
trace raw data.

enough for a test scenario.
I have tested the babeltrace conversion by saving the console output
to a text file on host manually
(https://vidushivashishth.github.io/eighthpost/).
Could you please integrate the content of this blog post in the
repository and automate the manual steps in it.
Can I use sockets to transport the traces from target to host instead?
Will that be feasible? I have already created a client and server side
program and tested a text file transfer. This is working.
You can communicate via sockets on some simulator BSPs, however, in the
scope and state of the current project, I think this is not feasible.

I am implementing the last option.
Before you implement anything, could you please first outline what you
want to do.
