How to get pdb working for micropython?

[pluess]

I have watched https://www.youtube.com/watch?v=RRN_ngx01vM (A Debugger for Micropython?) an wanted to try this myself.

I followed the Instructions to build Micropython and got settrace working.
But where can I get pdb for Micropython?

micropython-pdb is just an empty dummy, that does nothing.

I downloaded the cpython pdb source from github which does not really work:

[560] : micropython -m pdb worldtimeapiunittest.py
Traceback (most recent call last):
  File "pdb.py", line 498
SyntaxError: invalid syntax
[561] :

So how can i get pdb running for Micropython?
