Part Number: DRA787
Other Parts Discussed in Thread: SYSBIOS

Print the callstack of function is useful for analyse issue.

Such as A function call B function, B function call C function, Can we add code in C function to Print the callstack A-->B-->C ? Which API to use?

Hi,

What is the software that you are using?

You can see the call stack in CCS while debugging.

We are using ti-processor-sdk-rtos-automotive-dra7xx-evm-04.03.00.05.

For small probability issue, we should print callstack in code.

Hi,

I don't think there is a generic call stack API that you can use.

You can add debug prints in different APIs or look at call stack in CCS.

Hi,

If you are using linux use gdb, whenever the breakpoint is hit you can print call stack using backtrace command.

We use sys/bios

Hi,

Please follow the first suggestion for SYSBIOS i.e. add debug prints in different APIs or look at call stack in CCS

Hi Rishabh

Sorry, I don't get your idea, how to add debug prints in different APIs? Sys/bios not have Callstack API, and only add debug info in functions?

Hi,

Yes, I meant that you add debug info in functions.

E.g.
A()
{
  print("Entering A");
}
