Part Number: TDA4VM

Dear

When the ISP library developed with TDA4VM(PSDK 7.1) is merged into TDA4 Low(PSDK 8.6), the ISP function does not work.

It was developed as a single cam application in PSDK 7.1 and the platform team is using the library as is in PSDK 8.6.

In the above version upgrade situation, is there a compatibility issue with the ISP-related API or DCC tool version, 

so is a new release necessary?

Best Regard

    Dear Brijesh,

    According to the platform team, only a black screen is displayed from ISP output.

    Hi KO,

    Can you please print the statistics and share us? There could be multiple reasons for the black screen, so lets first see if the chain itself is running fine. 

    Regards,

    Dear Brijesh,

    Platform team only asks me to check ISP library compatibility between PSDK 7.1 and PSDK 8.6.

    They said that additional design and debugging are still in progress.


    According to data provided by Korea TI FAE, the ISP difference between Mid and Low was the VPAC1 (VISS1, LDC1) and VPAC3 (VISS3, LDC2) versions.

    Could you please briefly confirm the compatibility between the above version differences?

    BR.

    VPAC3 adds only a few new components in VISS.

    DCC tuning tool and configuration (e.g., xml files) for VPAC1 should be compatible with VPAC3.
    TI PSDK has updated tivox s/w so that it is backward compatible.

    Which library is this about?
    Is it customer's own library on top of tiovx?

    Dear Gang Hua

    Yes. The ISP library is being developed and updated separately by the ISP 3rd party, and is designed to operate in conjuction with the new sensor driver.

    Hi Kibeom,

    Thanks for the information!
    It looks like 2A and VPAC tuning/control may both be included.

    H/W-wise, VPAC3 is very close to VPAC1 and should be backward compatible.
    On S/W side, there has been quite many changes in tiovx and PDK from 7.1 and 8.6 for supporting VISS.

    It probably will require the 3rd party to do some debugging.
