Why do I get ADI_ADAU1962A_TWI_ERROR when adding Micrium?

When I add "μC/OS-III RTOS for SHARC" to my working project (spdif audio playback) I get ADI_ADAU1962A_TWI_ERROR when initializing the DAC. 

I have only added the Micrium stuff to the project, not done any calls at all. 

Any suggestions?

    I added the uCOS in system.svc to a newly created "spdif playback" project from the examples, and started the debugger. This is the output:
