Debugging third party operating system code using crossworks/crossconnect

Can you debug a third party operating system imaging using crossworks and crossconnect hw debugger if the image was built without using crossworks compiler with debug symbols? I want to use the RTEMS OS which has its own tool chain to build its image/exe. My plan is to develop and debug my application code using crossworks/crossconnect tool chain separately on my development board, and then integrate the code into RTEMS OS image build using RTEMS's own tool chain and then use the crossworks and crossconnect hw debugger to debug my application and RTEMS OS code running on the RTEMS OS image on my development board. My development board is the Raspberry Pi. Is this possible and what are the detailed steps to configure crossworks tool chain, crossconnect hw debugger, and the raspberry pi. Luis
