CCS: CCS6 - step over doesn't work

Tool/software: Code Composer Studio

Hi all,

i am working on a new platform with TM4C129X and an Blackhawk USB 560V2 debugger and with CCS 6.1.3

I wrote a application using TI-RTOS with Tasks and Interrupts. Everything works fine when running free or run to breakpoints or 'run to here'.

But I have a problem when I try debugging within a task with 'step over'. Instead stepping over a sourcecode line, I fall into ti_sysbios_family_arm_m3_Hwi_dispatch__I: in the file Hwi_asm.sv7M

I can step through this function and everthing works fine, but I cannot step over!

Any ideas?

Thank you in advance

Hi Frank,
Does this issue only happen in a particular task for a particular function? Or is the issue more widespread?

If you can provide a reproducible test case, that would be great also

Thanks

One potential issue could be that you have the option to disable interrupts while stepping option enabled in the debugger options and that is impacting the execution:

Hi,
when I select the checkbox 'Disable interrupts when source stepping' step over works better, but I get another error (posted here):

The error then occurs while single stepping over Task_sleep()

Ah, I see you had disabled it based on the recommended in the other post. I will assign this thread to the TI-RTOS experts for further investigation.

Thanks
