+title: Debugging RTEMS with GDB

 RTEMS is difficult to debug, since the default GDB behaviour follows a language based approch and developer will have to debug the application+RTEMS stack as a whole. We are in process of developing a new set of extenstions for GDB to play nice with RTEMS. The intial code is available in this [github repository](https://github.com/dbalan/rtems-gdb).
