TDA4M : direct connection to AR0233 without Ser/Des

Other Parts Discussed in Thread: DM385

Hi

1CH AR0233 Camera with below connection, we only can see the Noisy image on Monitor screen. 

  - TDA4x EVM(CSI0) <-- Fusion Application Board(Spectrum Digital) <-- AR0233 Serializer(Leopard Imaging)

  - TDA4x EVM(CSI0) <-- Fusion Application Board(Spectrum Digital) <-- AR0233 Serializer(MARS)                                  

so we made own interface board like below connection.

  - TDA4x EVM(CSI0) <-- Interface board with AR0233 MIPI CSI 4CH(Without Ser/Des)

In this case, there is no image on TV screen. 

For test purpose we connect interface board with AR0233 to our own DM385 board, we can see the clear image on TV screen.

Currently we doubt about the version of PSDK_RA_J7_06_01_00_15 ?

Thanks In Advance

    Are you sure that the sensor configuration is correct? Can you please probe CSI2 Rx pins (clock + data) and share the waveform here?

    Hi

    Yes, with same sensor configuration, we could see the clear image on TV Screen with our own DM385 board.

    MIPI CSI2 data/clock is no problem, we already checked it with J52 of EVM Board

    Hi Mayank

    I tried to check Leopard Imaging and MARS module on TDA4x Alpha EVM and it works.
    But when I try to run two modules on TDA4x Beta EVM, it does not work.
    Do you have any idea what makes this difference between Alpha and Beta board?

    Thank you.
    Regards,

    Johnny,

    Can you please share failure details - logs will help.

    Also, please verify  that everything else is the same between the two HW setups - Fusion board revision, dip switches, display port etc.

    Regards,

    Mayank

    Hi Mayank

    Sorry for delayed response.

    As you mentioned before, we change the MIPI Band speed based on below table.

    and the modified source code is like below.

    Before changing, the code is locked at internal of tivxCaptureProcess() function.

    After changing, it locked at the internal of tivxVpacVissProcess() function like below image.

    When we skipped the function tivxEventWait() function, we can see the all green image on TV Monitor.

    Thanks In Advance

    I am still waiting for the response to my previous questions:

    1. Can you please share failure details - logs will help.

    2. Also, please verify  that everything else is the same between the two HW setups - Fusion board revision, dip switches, display port etc.

    Regards,

    Hi Mayank Mangla

    Still we are trying to solve this problem.

    Currently we can see the live view with below connection. 

      - TDA4x EVM(CSI0) <-- Fusion Application Board(Spectrum Digital) <-- AR0233 Serializer(Leopard Imaging)

      - TDA4x EVM(CSI0) <-- Fusion Application Board(Spectrum Digital) <-- AR0233 Serializer(MARS)

    Like above explanation, below connection is not working

      - TDA4x EVM(CSI0) <-- Interface board with AR0233 MIPI CSI 4CH(Without Ser/Des)

    We verified that the MIPI 4CH signal is input to the EVM and it looks has no problem.

    Best Regards

    1. Can  you please provide a waveform of MIPI clock and data signals?

    2. Can you please provide a dump of CAL registers?

    Dear Mayank

    We have 2 EVM board, one is OK and we tested AR0233 with FPDLink.

    These days we found that the other board we had tested with direct connection, is fault, CSI0_D2P and D2N is short at J52 connector.

    So we changed it to the good one with AR0233 direct connection, it finally works OK.

    The bad board, if we remove the J52, then CSI0_D2P and D2N is opened.

    I don't know why they send us this bad board without Testing it.

    Anyway thank you very much for your kind support.

    Best Regards

    Hi Mayank

    We have 2 TDA4x_EVM board. One has tested with FPDLink camera and it works OK.

    About this issue(direct connection) :

    These days we found that the other board has problem of CSI0_DP2 and DN2 shorted at the internal of J52 Connector.

    When we repaired the EVM it works OK now.

    I don't know why they send us this bad board with test .

    Anyway thank you very much for your kind support.

    Best Regards
