Error Debugging Custom ADSP-21489 Board: Failed to Reset Processor 0

Hi, I am attempting to debug a custom ADSP-21489 board using the ICE-1000 debugger and Cross Core Embedded Studio V.2.6.0. 

When I try to upload my test program I get the following error message:

An internal error occured during "Launching TapeDelay_V1 Debug".

[TpsdkServer] Failed to Reset Processor 0

Is there anything in particular this points to that I should test out when debugging? Testing with an older version of the same board my program uploads fine.
