To build packages with debug compilation flags, add the following to the conf/local.conf configuration file:

DEBUG_BUILD = "1" 

This changes the compilation flags to debug optimization as follows:

DEBUG_OPTIMIZATION = "-O -fno-omit-frame-pointer ${DEBUG_FLAGS} - 
   pipe" 

The -fno-omit-frame-pointer flag will tell gcc to keep stack frames. The compiler will also reduce the optimization level to provide a better debugging experience.

After building and installing the target images and SDK again, you can now follow the same process.
