             using GDB to debug on the target hardware.

+                To improve the debug information accuracy, you can reduce the
+                level of optimization used by the compiler.
+                For example, when adding the following line to your
+                <filename>local.conf</filename> file, you will reduce
+                optimization from
+                <ulink url='&YOCTO_DOCS_REF_URL;#var-FULL_OPTIMIZATION'><filename>FULL_OPTIMIZATION</filename></ulink>

+                Consider that this will reduce the application's performance
+                and is recommended only for debugging purposes.
