    Hi,

    I also have a similar requirement.

    We have a video decoder running on the DSP of OMAP 3530.We need to display the output on the LCD of the EVM.The codec is not XDAIS or XDM compliant as of now.So we cannot use the existing framework , i believe.

    Please some body can explain how can i do the display in this scenario.If possible we would like to do in Windows itself with CCS as we have very limited time.

    Please help.

    Thanks,

    Manoj

    The use of the LCD display on the EVM is only supported through the Linux display driver that runs on the ARM, there is no software collateral for using the C64x+ to display images on the LCD, this being said the only way we can support displaying video decoded by the C64x+ on the LCD is through the existing DVSDK framework software. If you were to display directly from the C64x+ you would have to write a video driver to control and display to the LCD which would be a significant effort. At the moment the best way to verify image output from the C64x+ in CCS would be to dump the image to a file and view externally or use the CCS image viewer (which currently requires planar data).

    Hi,

    This question is not related to above thread, but it is related to LCD on MISTRAL with OMAP3503 EVM.

    We are trying to replace 3.7" LCD(LS037V7DW01) with 7" LCD(LQ070Y3DG1A), I had taken care of modifying Linux display

    driver for resolution, input timing and other related info. I am not sure how to take care of contrast ratio configuration. Do you

    idea how to take care of contrast ratio setting in the LCD display driver for Linux?

    Thanks & Regards,
