TDA4VH-Q1: XJ784S45AALY-HS-SE-FS can not boot

Part Number: TDA4VH-Q1

Dear TI

Our latest PCBA use XJ784S45AALY-HS-SE-FS for eFuse programing，found several Soc cannot boot from ospi , there is no data and clk waveform about ospi when power on，
attempted to make some modifications as below。

MCU[9:8] 11 , can boot；
MCU[9:8] 01 , cannot boot；
MCU[9:8] 00 , can boot；

According to the specification,MCU[9:8] are the POST config pins,

What's the reason for the above.
Which POST  sequence we should use ,what determines the configuration of MCU[9:8]。

thanks

    Add more information:

    Post config Pins

    When the set MCU[9:8] 01, it can't start up. The details of phenomenon show as follow:

    OSPI flash data and clock no signal

    1.We have already double confirmed BOOT MODE pins was set correct.

    2. Power supply for MCU domain was normally because MCU_PORZ in high level state.

    3. There are two chips that will definitely reproduce this problem. Two chips accidentally reproduced this problem. Most of the chips are in normal condition

    Hi Kangjia,

    As you rightly pointed out, these pins are used to select different modes of POST settings. We will have to check with the HW team why BIST running in parallel is not working. Does it work fine in any other boot mode? Is it the issue only in ospi boot mode? 

    But I think setting it to 00 is working fine, which means BIST running in serial seems to be working fine, isn’t it? Any issue in running this setting?

    Regards,

    Brijesh,
    Yes, it nee HW team check why it can’t work normally with parallelly. Kindly please help loop HW expert to discuss and share conclusions to this link. Thanks~

    Kangjia,

    There are several register values that are questionable. Is this a very early sample??
    Please try with another device.

    I cannot explain why the part does not boot, but I can tell you that you are not really running a self-test.

    Hi Kevin,

    It should be early sample. what's the details of register values that are questionable?

    In order to start up normally, customer close self-test and read register. It can't read register value if not close self-test.

    How to debug in next steps? Thanks~

    There are a couple of things that are strange -- one is that the pattern count is 0.
