4 years ago It looks like you haven't implemented CrashCatcher_GetMemoryRegions() properly and CrashCatcher isn't dumping the contents of RAM correctly. A sample implementation can be found here. You would need to customize it for your particular microcontroller. I think it should look something like this for the nRF52840:
extern "C" const CrashCatcherMemoryRegion* CrashCatcher_GetMemoryRegions(void)
{
static const CrashCatcherMemoryRegion regions[] = {
{0x20000000, 0x20040000, CRASH_CATCHER_BYTE}
};
return regions;
}What you do see it dump of your call stack is based on the contents of the PC and LR registers. To dump anymore of your call stack will require the contents of RAM, which includes the stack.
I hope that helps.

Hi,
I'm trying to integrate your great library into my project. Unfortunately I encounter some problems. My example application looks like this:
The Crash dump:
and the gdb output:
Is there a way to understand the problem in more detail? Why is the stack not fully unwinded until main?
