+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).
+
+To use the extenstion, 
+ - Clone the repository
+{% codeblock lang:bash %}
+git clone git@github.com:dbalan/rtems-gdb.git
+{% endcodeblock %}
+ - Assuming you have a working [RTEMS toolchain](/blog/2013/05/28/getting-started-with-rtems-on-archlinux/), spin up the GDB and source the code.
+{% codeblock lang:bash %}
+$ sparc-rtems4.11-gdb
