How to printout callstack , like using backtrace function in glibc

Seongyon_Jeong — Thu, 14 Dec 2023 02:27:47 GMT

Hello, everyone.

IMX RT 1020 EVK board, OS-FreeRTOS, SDK-2.x_EVK-MIMXRT1020 2.13.0

MCUXpresso IDE 11.7.1

I am looking for the easiest method that prints callstack.

first, I tried to include [ execinfo.h ] , but It does not works

and I found it does not exist in plugin path<< == ~~\tool\arm-none-eabi\include\ xxxx.h

I need to check callstack - method to print-out in debugConsole in RunTime, not IDE-debugMode

So, Is there any guide ?

What is the best & simple way to print callstack on terminal, like bactrace function in execinfo.h ?

Hi @Seongyon_Jeong,

The only thing I found was this blog post by our colleague Erich, please take a look into that: https://mcuoneclipse.com/2015/10/03/freertos-arm-thread-debugging-with-eclipse-and-gdb/

Other than this, I'm afraid we do not have more resources or documentation about this topic.

BR,
Edwin.
