RP2040 debug
Dec 5th, 2023 at 8:55am
Print Post  
Hi, I'm trying to debug a program with RP2040 and a pico-debug [re-flashed 1.03].
Debugging from 'start debugging' play button doesn't work, it launches but seems to stick at an odd bit of code- i.e. wire library.
Debugging by programming and then 'attach to process' sort of works but runs to the first breakpoint in loop.
- it neither stops at the beginning of loop or breaks on any breakpoint in setup.
- if I set a breakpoint in a function and the break seems to happen elsewhere in a different function.
What's going wrong ???

Thanks for the report and the logging information.

If you add a Local board.txt to your project (vMicro > Add Code > Add Local board.txt) and paste in the contents of the below file, does this help with landing on breakpoints in loop(), and any other functions you have set?

Hi, it seems to have improved the 'start debugging' play button - it now operates the same as attach to process.
There is a breakpoint in setup which isn't hit, it seems to be breaking and automatically restarting in line 96 [the actual breakpoint is in line 90] and eventually hits the breakpoint in 201.

Thanks for the link, however that video shows VSCode which is a different product and will use different packages to configure and run the debugging.

This forum and thread is only for Visual Micro in Visual Studio.

Hi Simon, is there anything else I can try ?
Is it worth uninstalling and re-installing VS &/ VM ?

Can you try adding a delay at the very top of setup() (e.g. delay(5000)), and then use the Start button again?

This seems to allow the debugger to connect before the delay has finished, so you should be able to debug the code within setup.
