uPP Demo Code Does Not Work

I have download upp_bios_drv_v1 code from the Wiki site to learn how to use the uPP.  The code compiles and runs until I execute a GIO_write to begin the DMA.  The program seems to go off, however I know the DMA went off because I was monitoring the destination memory.  I do not receive an interrupt indication and therefore I am stuck waiting for a signal to indicte the DMA is complete.  The only change I made to the code was to replace the log printf's toprintf's.  I am try to run the AB Digital Loopback mode.

    I have made some progress.  I can get the application not to hang by not enabling interrupt HWI7.  This would indicate that the demo code is not setting up the interrupt correctly and the system does not what to do when it gets the complete interrupt.

    I fixed my problem and have the demo code working.  I have one concern though.  I am using CCS5 to build and debug the application but the driver was built with CCV3.  When I tried to rebuild the driver with CCS5 it gave errors when I tried to link with it.  I got allot of undefined labels indication the underline files are not compatible with CCS5.  Is there any plans to generate the driver using CCS5?
