CCS/AM5716: Unable to see the values in the registers

Part Number: AM5716

Tool/software: Code Composer Studio

Hi. I am trying to use the interface between the MCASP and the DSP of the AM571 6, but every time I try, during the debug, to watch the registers state, I get this error screen.  Any solution for this?

    Hi,

    Depending on the device, the memory that is configured for a given register may cause a core lockup if the peripheral is not properly initialized - the device's memory controller can assume this is a critical bus error and lock the core. 

    Another possible scenario is if another resource is locking up the memory mapped register (DMA, for example). In this case, the core CPU is never able to complete the memory access operation and be left in a state where it waits quite a long time for the operation to complete. 

    Additional details can be seen in the section "Device hung" in the Debugging JTAG page below.
