Dont think about nuttx like you do with linux with isolated processes
and apps loaded from disk files :)
it's more like a *very* advanced set of arduino libs in most usual cases.
(others dont hit me, I know this is extreme simplification.)
if the microros app is compiled in your os image, then you can probably
put a breakpoint on the microros_main() function, then launch microros
with nsh, and your breakpoint will just trip.
For that you need to connect to your nucleo stlink using openocd and
gdb. There are tutorials around there, this is just about generic
embedded debugging techniques.

Danke Sebastien
The application (microros) is configured and compiled by the nuttx
generation. But if the routine is in the shell, how can I start it
from the debugger?
Thanks in advance

Hi,
If your OS is built in monolithic mode (no protected mode) then
applications are just routines, so you can put a breakpoint in any
app routine and let it run until there.
To replace nsh by your app, do make menuconfig, menu RTOS features,
menu Tasks and scheduling, text config "Application entry point".
But it is not necessary to replace the default app, you can launch it
with nsh and still hit a breakpoint in your launched app.

Hi
I'm working on my nucleo-144 board, trying to get a microROS working
again under NuttX.
Thanks to a unique change in a microROS file, I've reached to
recompile all the files again and I can obtain the microros
application as described here:
https://github.com/micro-ROS/micro_ros_nuttx_app apps/microros
The application doesn't correctly work yet, and I'm looking for the
problem. I'd like to debug the microros application, but the
debugger shows (as expected) the nsh task. It is possible to start
the specific "microros" generated program or I have to set it as
entry point? Otherwise, how can I attach this task to the debugger?
I'm able to debug the nsh application with the methods described on
the NuttX documentation about debugger. Thanks in advance Roberto
