    Hi,

    Yes. You need to write the SPI transfer function (Controller to ADV7625). As mentioned before, If you are using Internal flash memory option, external flash is not needed.

    Still we are wondering and want to check the labels displayed with our evaluation correctly after burning out your changes(OSD is with junk normally).

    Please let us know if you are still facing any issues, we will check with our evaluation platform.

    Thank you.

    Thanks,

  • Hi,

    When I have blocked SpiTransfer function, it can still be displayed correctly after burning it.

    (blimp operation)

    Drag in six labels, change the memory option to internal storage, and change the resolution to the current resolution.Then the TV will display the six labels correctly

    Thank you for your patient answer!

  • HI;

    Do you have any experience of successfully porting to the arm board?Can you give me a demo?Let me see how you implement osd display。

    thanks

    Hi,

                  Are you saying, removing SPI flash from eval board as well as commenting out the SPI transfer function right? Can you share the details what are commented from code( source filename and APIs etc)?

    Drag in six labels, change the memory option to internal storage, and change the resolution to the current resolution.Then the TV will display the six labels correctly.

                 We assume that this statement is for Eval board, Is it right?

    Do you have any experience of successfully porting to the arm board?Can you give me a demo?Let me see how you implement osd display.

                 Please refer Advantiv_CrossPoint_Application_Userguide Appendix A which explains  OSD integration with HDMI driver code which is available at ADV7625 ADV7626 ADV7627 evaluation board software package documents. This document explains for Blackfin based eval board with VDSP. The same way you can integrate for ARM also. Please let us know if any issues?

    Thanks,

  • hello;

    1、My spi function is empty, as shown in the figure below

    • 2、yes,All operations are on the eval board
    • 3、I looked at the data that you gave me, but there was very little information on the transplant part.
