Other Parts Discussed in Thread: TMS320C5505

Dear:

 

 I have also tms320c5505 EVM with Pulse oximeter board from ti, with no NAND memory (EMIF interface)the problem is when i load the .out  file of pulse oximeter supplied from TI.

it does not work. no display appears and no serial communication. Can any one tell me any reason. Is NAND memory or other kind of memory in EVM card is essential for proper

operation. 

 

Thanx in advance.

    Fayaz,

    Are you building the application or loading the .out that comes with the kit?  The version that I built is targetting the internal RAM memory of the VC5505.  You shouldn't need external memory unless you want to run application in stand alone mode, then you will need the memory daughtercard available from Spectrum Digital. 

    As to why the application doesn't appear to be running, there is not enough information.  I have gotten the application to run successfully on my board.  Do any applications run on the board?  Can you tell if your PulseOx application loads and boots correctly (try Run to Main under Debug drop down in CCS)?

    Regards.

    Hi ToomyG,

    I am not using the board in stand alone mode, i am just checking the SpO2.out   which is supplied with AFE.

    i think there is some doubling about I2C communication. Can you tell me to whom components I2C communication is performed.

     

    Thanx

    Muhammad,
    I don't understand your question about the I2C communication.  Can you rephrase your question?  Why do you think there is an issue with I2C?

    Have you registered your AFE?  If so, you can get access to latest software versions of the application code.  I would try this to see if the code is working correctly.  I have used the latest release on my MDK system and it is working correctly.

    To double check a couple of points:
    - Did you setup all the HW and SW according to Quick Start Guide and Application Note for Pulse Ox?
    - You are using the VC5505 EVM and not the C5515 EVM correct?  The C5515 EVM uses different code.
    - Do you have Pulse Ox sensor attached to the AFE?  It is not necessary to get the application to run, but there will only be partial display since no data is available.

    Regards.
