RE: Debugging a specific application
Thanks to all! I've put the entry point to my application and I can now debug it using the methods described in the NuttX documentation! This is probably the simplest way to debug a specific app. Best regards Roberto Inviato dal mio Galaxy Messaggio originale Da: Marc Rosen Data: 01/12/22 13:36 (GMT+01:00) A: dev@nuttx.apache.org Oggetto: Re: Debugging a specific application Hi, mind to check if in menu Library Routines the option "Support Builtin Applications" is set?

Hi, mind to check if in menu Library Routines the option "Support Builtin Applications" is set?

Re: Debugging a specific application
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?

Re: Debugging a specific application
Not sure if it helps, but the built-in apps can be easily debugged, so could you perhaps include your application as a custom app, selected via the NuttX Kconfig so it gets built in, then start it from the nsh? A workaround maybe, but might help? On 30/11/2022, 05:40, "Roberto Bucher" wrote: Hi I'm working on my nucleo-144 board, trying to get a microROS working again under NuttX.
