Debug CCS F28M35H52C

Yes, I did. I try to debug simple, code

while(1)

{

Task_Sleep(10);

LedOn();

Task_Sleep(10);

LedOff();

}

If i set a breakpoint on LedOn();, I will stop at this line. If I press "Resume", I will stop at this line ( at line with LedOn();).

Resume .... Stop at LedOn()..... Resume .... Stop at LedOn().....Resume .... Stop at LedOn().....Resume .... Stop at LedOn().....Resume .... Stop at LedOn().....Resume .... Stop at LedOn().....Resume .... Stop at LedOn().....Resume .... Stop at LedOn().....Resume .... Stop at LedOn().....Resume .... Stop at LedOn().....Resume .... Stop at LedOn()......................

Its all right!!!

Than, when debug is stoped at LedOn(), I press "Step over" and immediate fly to loader_exit(). Why? How to debug step by step?

There was the thread Step Into (F5) and Step Over(F6) not working on CCS 6.1.3.00033 where changing the CCS project properties to NOT disable interrupts when Assembly Stepping or Source Stepping prevented a Cortex-M4 SYS/BIOS program from failing with a SYS/BIOS exception when Step Over was used.

Maybe that will help you to avoid the problem.

Note that the cause of the SYS/BIOS exception in the referenced thread is not yet known.

Hello freinds. Can you help me? How to debug step by step?

How's it going? How to debug step by step?

Hi,

You are putting the breakpoint for code running from RAM or Flash? Also this is C28x code or M3 code? On C28x we have only 2 HW breakpoints and if these are already used then no more HW breakpoints will work.

Also sometime if code get optimized then you may not be able to put the breakpoint in 'C' code. Try assembly code instead. You can view it by clicking on "View" -> "Disassembly".

Hi,

code running from Flash. this is M3 code.

I don't understand where static void loader_exit(void) is in your code base and what is the purpose of this function.

I am not sure what error SYS/BIOS is detecting, but maybe a "Scan for errors" in the ROV will highlight the error.

I don't understand where static void loader_exit(void) is in your code base and what is the purpose of this function. Please check the references of this function and put additional break points on each of the callers of this function when you do step over and see which external event is triggering this function call.

hello Athuru

how must I do debugging? Do I have to set the checkbox "Disable interrupts When assembly stepping" and "Disable interrupts When source stepping"?

I would suggest to leave the settings as they are and put break points in the callers of loader_exit() function and repeat the steps that produce the error scenario.

Let me request to move this thread to TI RTOS forum who can give more insight on why loader_exit() is being called when you do source level step over and not when you run between break points.

What is the exception? You can watch the exception portion of this video to see how to get the reason:

Does the problem happen when you disable the interrupts for source stepping?

What is status of the WDT?

The state of the STALL bit after reset is zero, which means the watchdog timer stops counting when the microcontroller is stopped with a debugger.

Therefore, unless the program has enabled the WDT *and* set the STALL bit I don't think the WDT explains the observed behavior.

Hello

Sorry for my English. Please allow me to make a movie screen, where you will be able to see my actions, settings of CSS and debugger.

Why do I always get to the Hwi_asm.sv7M?

What is status of the WDT? - How and when to watch the status of the WDT?

This was helpful! Can you include the debug window? I'd like to see the callstack when you are in the assembly. For example:
