CC2642R: Stack lockup

Hi,

I have assigned an expert to comment on this behavior. In the meantime, I have a few questions that may help us get to the bottom of this more efficiently. Is this software running on custom hardware or a LaunchPad? If it is currently running on custom hardware, then can you verify if this behavior is seen on a LaunchPad? Is this behavior occurring only after you have made modifications to the simple_broadcaster project or always?

Best Regards,

Jan

It is running on custom hardware.  I can try to run this on a Launchpad.  I have made modifications to the simple_broadcaster project, but only to add a task that communicates via uart.  The structure/content of simple_broadcaster is basically untouched. 

I loaded the code onto a Launchpad and it exhibits the same behaviour, stops at the same assembly code.

Is this still being looked into?

Greg,

Please apologize for the delay; this thread fell under my radar.

I see that Daniel is helping you unlock JTAG access on your other thread.

The location you see is in ROM, but the disassembly view is very narrow in scope and could be reached by a number of scenarios (more specifically, why the register R0 equals zero).

In these cases, the broader context before reaching this position in code tends to be much more useful. I suggest looking at bit more broad scope and see what function call and parameters are triggering this - which I suspect you already did, given you drilled down to this exact point in code. 

The debugging section of our User's Guide is useful to help track the source of these issues:

One additional aspect that helps is to trace back modifications done recently to get an idea on what may have been the trigger for the issue - an unallocated buffer, a bad reference pointer, etc.

Hope this helps,

Rafael
