RTOS/TDA2PXEVM: SD card Read Write Processor SDK 3.02

Hrishikesh Rajurkar
Expert 1165 points

Part Number: TDA2PXEVM

Tool/software: TI-RTOS

Hi 

We are working for a system based on TDA2px . The system will be BIOS only. The PDK being used is PROCESSOR_SDK_VISION_03_02_00_00

As I understand the sample example ..\PROCESSOR_SDK_VISION_03_02_00_00\ti_components\drivers\pdk_01_08_01_06\packages\ti\drv\stw_lld\examples\mmcsd\sd_file_io

deals with SD card file system read write test running from IPU core.(from make file provided in the same example)

Please let me know if this is correct and  if SD card can be accessed from other cores for file read/write operations.

This feature is needed along with ability to boot from SD Card.

regards

Hrishikesh

    Hi Hrishikesh,

    This is correct. Yes you can access SD card from other cores as well.
    SD boot is also supported for TDA2Px.

    Thanks Risabh for quick reply.
    So to access SD card from other cores, we will need to build the sample code for other cores, and no other changes should be required, Is it correct ? Also for customized board, are there any other things we need to take into account ?
    As per requirement we need to support the ability to manage files on the SD Card from all cores.
    regards

    Hi,

    Porting will be needed for other cores, example/driver will not work straight out of box.
    Changes depend on the application like interrupt configuration, EDMA channels, etc.
    For custom board you might need to take of pin mux as well.
    I would like to clarify one more point.
    SD boot will work only from the master core i.e. A15.
