Problems interfacing the ADS1298R with TMS320C5515. Program loads onto device but no signal shows up!

Other Parts Discussed in Thread: TMS320C5515, ADS1298R, ADS1298

I'm having problems interfacing the ADS1298R with the the TMS320C5515. I successfully loaded the program onto the device but my display screen on the EVM C5515 only shows a small dot that moves across the screen. It doesn't show my ECG signal that my signal generator inputs.  I have read the related forums about these issue and it didn't solve my problem.  Also I have 8 warning items that stat. Could you please help me resolve these problems. Thanks

-entry-point symbol other than "_c_int00"specified: "reset_isr"

-variable"cs_flag"was declared but never referenced

    Devlin,

    What program are you referring to? Is the ADS1298R on an EVM? Your own board? What is the TMS320C5515 on exactly? Which EVM? What are your hardware connections to the ADS1298R? Do you have scope captures of the ADS1298R to TMS320C5515 serial lines?

    We need a lot more details to be able to help you.

    I have the ADS1298R Front-End mounted on the C5515EVM.  I have a USB connection from my computer to the c5515 EVM.  I download the ECG software for the ADS1298 from http://code.google.com/p/c5505-ezdsp/ .  I imported the code to CCS V.4. I read through all the forums and made all tweaks and  necessary changes that was needed to import these two files. My problem is what I stated above. Do you need me send a picture of my connection to clear up any details.

    Don't get confused because I don't have my ECG cables hooked up on this pic. I disconnected them  for Picture purposes.

    This is my display screen.

    Devlin,

    Your question is out of scope for this forum. I will be moving this to the C5000 forums, since they are behind the sample project you're referring to.
