Using backtrace functionality in nrf52

[Swapnil]

I want to add backtrace functioanlity in nrf52. I am using functions given in below link: link text

But I am not getting library files for defining functions mentioned in backtracing function.

If you have any idea how I can implement this backtracing functionality please tell.

So which functions, exactly, are you missing?

Note that the article specifically states, "On some platforms, gcc has a built-in function..." - have you verified that your particular unnamed toolchain does, in fact, have this ... ?

Sorry if my question hasnt been specific enough, so I will try to clarify that...

I basically want to get the unwind-library working for the nRF52832, so that no matter where I am experiencing a runtime-error, I can easily check the printout with the specific function-name and code-line where the crash happened.

I was hoping to get some more informations regarding this issue, in case someone already tried to link an external library for the nRF52832 or might even has used some advanced error-tracing function in the nordic-SDK.

This is actually a generic GCC/Cortex-M4 question - not specific to nRF52.

So you may well be better looking for general GCC/Cortex-M4 sources/forums...

I haven’t seen anyone use that backtracking library with the nRF before. In order to “unwind” and “backtrack” a common approach is to use the Call Stack and Locals Window in Keil.

But, as I said, it's not specific to nRF - it's general to any Cortex-M4F
