Hello Vidushi,
the RTEMS Trace Linker is definitely an interesting tool to track down
difficult and specific issues. However, this is a nice to have optional
feature from my point of view. We should focus on basic functionality
and this is interrupt entry/exit and thread switching. This should work
out of the box without having to compile RTEMS with specialized
configuration options. It should work via a serial line and network (UDP
I guess). It should also support SMP machines. This requires
per-processor trace buffers. The trace buffer should work without locks,
e.g. only interrupt disable/enable. I would do also a short review of
existing trace solutions. Maybe we don't have to re-invent the wheel.
For example:
