I have a working project, but from some point on, when I start it in Debug mode, it doesn't stop in main.c, but stops in one point in the code before main...

Debugger reports trace/breakpopint at ucHeap() 0x20011b88 ....

If I click on Run->Reset, the projects resets correctly, in main.c or Reset_handler if I set additional breakpoint...

I've checked and cleared all breakpoints, but this still happens...

Obviously something happened, probably in project settings. Where can I learn more about how exactly is project started and where to start checking what is wrong ?

Thanks in advance, regards.

do you run code from the RAM? I syspect wrong bootx settings – 0___________ Apr 24 '20 at 09:41
Hi, thanks for response... It's simple embedded project, I guess the code is run from Flash... – user2064070 Apr 24 '20 at 10:02
*` trace/breakpopint at ucHeap() 0x20011b88 ....`* looks like SRAM for me – 0___________ Apr 24 '20 at 10:57
sorry, you're right... It's a FreeRTOS based project... Project probably runs something from RAM. But what bugs me is why it gets there and why it stops at that address ? – user2064070 Apr 24 '20 at 20:28
it seems that ucHeap is basically heap space for FreeRTOS.... – user2064070 Apr 24 '20 at 20:55
I know what it is. you breakpoints are triggered when data is executed. Address shown shoes the address where breakpoint happened – 0___________ Apr 24 '20 at 21:26
