Issue with bringing up Pulse Ox demo software

James McPherson
Intellectual 340 points

I am trying to bring up the Pulse Oximetry demo software.  I have the analog front end, and a EVM5515 DSP board.  The instructions in the Application Report (SPRAB37A) are for the CCS v3.3, while I am trying to use the latest v5 version.  Also there are errors in the application report, that are addressed in the DSP Wiki, but this also references an older version of Code Composer.  Basically I need to know first where do I copy the c5505evm.gel, file in the latest version of CCS?  How can I implement section 6.2 of the instructions in the application report using the v5 version of CCS?  Please help.

    Hi James,

    You can use the evm5515.gel file that is stored in CCS directory - <CCS4 install dir> \ccsv4\emulation\boards\evm5515_v1\gel\evm5515.gel

    But the Sp02 project does not even need a .gel file - PLL gets configured in cpu_clock_init.c

    You can create a target configuration without any GEL file.

    Sometimes the GEL file is required to initialize external memory like SDRAM so that program code can be loaded into SDRAM but not in this project.

    Hope this helps,
    Mark
