#134 Pb in debugging session.
Hello!
I can't have a debugging session working correctly with a STM32F417IE.
When I click on launch, A tab keep beeing displayed with errors such as :
No source available for "(gdb[9].proc[42000].threadGroup[i1],gdb[9].proc[42000].OSthread[1]).thread[1].frame[0]"
No source available for 0x0
No source available for 0x<more complex="" address=""> (eg. 0x80123251)
In console: I have this output :
Starting target CPU...
...Target halted (PC = 0x030CF002)
Reading all registers
Removing breakpoint @ address 0x08001304, Size = 2
WARNING: Failed to read memory @ address 0x030CF002

Basically, I can't have my program running and I can't see what is in memory.
Thx in advance for your answer!
Here is the output of your project, executed on a F407:

If you use the -DOS_USE_TRACE_SEMIHOSTING_DEBUG, you need to Enable semihosting in the debug configuration.
Maybe the template is not compatible with STM32F417

I doubt so, 417 is very similar to my 407, and both share the same CMSIS headers and library code.
the only difference is the list of interrupt vectors, which you can easily check if it is appropriate for your processor.
once your program crashes, it should be no surprise that it accesses illegal addresses.
to diagnose it you need to trace it up to the point it crashes, not after it.

What about the first 0x0 I got?
a closer look shows that you messed the debug configuration; you changed the initial connect speed, you disabled the 'Continue' button, used absolute paths, etc.
restore defaults in both tabs, configure paths properly and it should work.
You are right, the first 0x0 was due to misconfiguration (i changed a lot of things trying to find a solution to my pb). Now I will sort out the pb with the clock stuff.
Thx for your help.
Hum it does not always crash at the same place ...
I cannot reproduce any crash, I duplicated your build configuration, restored defaults in the Debugger and Startup tabs, and it just works.
Thx for your time. If I come up with a fix. I'll let you know.
any progress?
I did not had time to look further into it, yet. Sorry.
Hi,
I eventually found out what as the pb (with some help).
In _initialize_hardware.c, l140:
RCC_OscInitStruct.PLL.PLLM = (HSE_VALUE/1000000u);
It is evaluated to 8 with current parameters, my setup needs 16.
Apparently the board I am using has a quartz with a different frequency than the one on the dev board.
One last question:
Where is configured HSE_VALUE?
Thx
in C/C++ General -> Paths and Symbols?
in the Wizard?
Yep. Thanks.
Sorry for noob question.
