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.

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, spin up the GDB and source the code. {% codeblock lang:bash %} $ sparc-rtems4.11-gdb
