    Hi,

                       In the linux driver code at location arch/arm/mach-omap2/board-ti8148evm.c I think that pcf8575_client->adapter pointer which contains the reference to "pcf8575_client->adapter->algo->master_xfer"is not getting populated anywhere and it is throwing the error 

    I2C: Transfer failed at vps_ti814x_select_video_decoder 195 with error code: -110

    please help to resolve the error.

    Thanks,

    Sudheer.

    Sudheer,

    Could you please provide more details? Are you using DM8148 EVM or custom board? Are you using EZSDK 5.05.02.00 / PSP 04.04.00.01? Are you planning to use OMX or V4L2?

    Regards,
    Pavel

    Hi Pavel, 

                            I am using DM8148 EVM,  EZSDK 5.05.02.00, planing to use OMX and I think OMX intern use V4L2.

                            I populated the code for 576i and try ed to capture the video data from 576i input, due to which i was getting the above error and I was not getting the above error when I am using the 1080i input for capturing and I am able to capture properly.

    Thanks,

    Sudheer.
