CCS/AM5728: DSP debug issue

Part Number: AM5728

Tool/software: Code Composer Studio

Our application requires DSP & ARM cores. Hence, in the past OMAP L-138 was used which posed ARM issues (ARM goes to Unknown state) while debugging DSP in RTOS (integrity) environment. Some work around was done at system level then to overcome the same.

Now, we are upgrading the hardware hence AM5728 is being considered. But, will the same issue persist in Sitara series too ? (Local, Bangalore, TI sales team is unable to provide us clarity about the same). If so, then recommended will be separate ARM and DSP processors? If yes suggest 1 Single/Dual core ARM core processor and 1 dual core DSP processor with possible interface between them.
