1. Change to the project directory:

   $ cd <plnx-proj-root>

2. Add the following lines in <plnx-proj-root>/project-spec/meta-user/conf/user-rootfsconfig:

   CONFIG_myapp-dev
   CONFIG_myapp-dbg
   

3. Add the following lines in <plnx-proj-root>/project-spec/meta-user/recipe-apps/myapp/myapp.bb.

   
   DEBUG_FLAGS = "-g3 -O0"
   
   # Specifies to build packages with debugging information
   DEBUG_BUILD = "1"
   
   # Do not remove debug symbols
   INHIBIT_PACKAGE_STRIP = "1"
   
   # OPTIONAL: Do not split debug symbols in a separate file
   INHIBIT_PACKAGE_DEBUG_SPLIT = "1"

4. Run petalinux-config -c rootfs on the command console:

   $ petalinux-config -c rootfs

5. Scroll down the user packages Configuration menu to Debugging:

   Filesystem Packages   ---> 
   PetaLinux Package Groups --->
   apps   ---> 
   user packages   --->
   PetaLinux RootFS Settings  --->

6. Select user packages.

   [X] myapp-dbg
   [ ] myapp-dev

7. Select myapp-dbg. Exit the myapp sub-menu.
8. Exit the user packages sub-menu, and select Filesystem Packages > misc > gdb.
9. Select gdb, and ensure that the GDB server is enabled:

   [ ] gdb 
   [ ] gdb-dev 
   [X] gdbserver 
   [ ] gdb-dbg
