TMS320C6748: SD card as storage device

Part Number: TMS320C6748
Other Parts Discussed in Thread: OMAPL138

Hello,

I am looking for code to implement using the sd card slot as a external memory device. Is it possible to receive a signal to the DSP board mentioned "TMS320C6748" and store the digital interpretaion of that signal to the SD card to later be offloaded to Matlab or some other modeling software?

Thank you in advance,

Brian Dougenik

    It should be possible to use the mmcsd to store data on it. You can check what examples are available in Processor SDK RTOS:
    ykovachev@lin-0373:~/ti$ cd pdk_omapl138_1_0_5/
    ykovachev@lin-0373:~/ti/pdk_omapl138_1_0_5/packages$ source pdksetupenv.sh
    ykovachev@lin-0373:~/ti/pdk_omapl138_1_0_5/packages$ ./pdkProjectCreate.sh OMAPL138 all little mmcsd all dsp

    However they probably won't support your use case exactly, you may need to modify the source code.

    For using the data later in Matlab, you should contact Mathworks for support.

    Best Regards,
