not really using cdb file

When I rebuild the project with the cdb file in it in ccs, I get an error saying

I dont really think that the DSP/BIOS bit is working. I am not actually sure if it is worth pursuing as the RTDX tutorials from simulink do not use dsp/bios setup.

I think that I need to pursue the rtdx interrupt mask to ensure that high priority interrupts (ie current sensor info) override the rtdx calls.
