Received a SIGINT: Interrupt

[Anonymous]

Hi,
I am usin VisualGDB 4.1 and Visual Studi 2012. I am trying debug STM32F3Discovery board according to tutorial. But I have two problems. The first is, the program don’t stop runing in main. And the second one is, when I pres Break All button I get a dialog box with the text “Received a SIGINT: Interrupt” or with the text “Received a SIGTRAP: Trace/breakpoint trap”

Hi,

The SIGINT and SIGTRAP signals are supposed to happen when break all is used, that is how break all works for that platform.
For the first issue, please give us a full gdb log. You can enable diagnostic gdb logging on the GDB settings page of VisualGDB Project Properties. Then start debugging and replicate your scenario (set a breakpoint in main before starting debugging), stop debugging and give us the log file from your project directory.

Hi,

I understand the SIGINT and SIGTRAP signals are used for break all, but I don’t understand why I have to be informed about it by a dialog box every time when I press the break all button. When I tick the checkbox “Break when this exception type is thrown” nothing is changing and the dialog box is shown next time again.

For the first issue, there is a log:

Hi,

Thanks for the details. The message box was originally used to provide information about the exact signal gdb reports, however it does indeed look redundant when the only information it contains is the SIGINT name. We will add an option to filter it out in the next release.

Regarding your gdb log, it looks like you are not setting any breakpoints. The only -break-insert command sets a breakpoint in main() and this breakpoint is successfully hit later. Could you please share a screenshot of your breakpoints? Are you setting them before running your firmware or when it’s already running?

Hi,

Thank you for solving my problem in the next release.

You’re right that I have not set any breakpoint. But I tick the checkbox “Support ‘step into new instance’ through breakpoint in: main”. I think it is the one -break-insert command in the log, but the program does not stop there.

Hi,

In order to automatically get stopped in main(), start debugging by pressing F10 (step into new instance), not F5 (start new instance).
