What support do you need?
It should currently be possible to do this if you do these steps:
1. Install the compiler
2. Set it up inside codeblocks
3. Create empty project which uses this compiler
4. Add files
5. Setup build options for your device
6. Add post build commands to do firmware gathering or/and upload in your environment.
7. enjoy
If you need to do these steps often you can write a wizard template script which automates the stuff above and then provide a patch for inclusion in the C::B releases.
