Great you have had some success but there is a lot more work before it is usable.

Mritunjay, can you see what is wrong here? Lets have a look ...

$ stat $HOME/development/rtems/5-arm
stat: /home/chris/development/rtems/5-arm: stat: No such file or directory

This will not work for me and it will not work for an RSB vertical stack build.
This last requirement is important.

You cannot hard code values. The RSB provides the RTEMS version, BSP details and
paths as RSB macro variables. Please review these by using the --trace option
and log file and please ask if you have any questions.
