I was able to install the suite, build the board support package, and test my BSP though along the way I had to replace "5" with "6" in certain commands. Everything went well until I wanted to prove I can work on RTEMS. I followed the instructions to create my hello application and added the necessary .c files. The problem was when I tried configuring this application using waf with the command:

This is really great and you are very close. We definitely do want you
to be using '6' and not '5' for GSoC.

Although you can create a standalone hello application, and that would
be an excellent way to show some progress, for the GSoC "proof" we
actually want you to modify the hello that gets built as part of
rtems. Its source is located in rtems.git/testsuites/samples/hello

Then you will rebuild rtems and it should recompile your modified hello sample.

Everything went well with me not not having to change any "5" to "6" in some commands. I didn't make it as far as testing my BSP. I had issues with configuring my BSP with the command:
