TUSB9261-q1 question

Prodigy 30 points
Other Parts Discussed in Thread: TUSB9261-Q1, TUSB9261

my chip  is   TUSB9261-q1 （Automotive grand）

 I   take the Firmware Binary File (e. g. TUSB926x_FW_v1.04_SATA_NO_POLARITY_SWAP.bin) and load it with the TI Flashburner Tool. In the Advanced Descriptors Editor (Button on top of the window), check "HID Enable", UAS Enable" and "self-powered". Then, Export this data to a bin  file. Write this exported bin file (not the original Firmware binary!) to a Flash, using an appropriate programmer.。my  board is running ，MISC_LED0#（PWM1）is   flashing. but  on   the  demo  board  SW_HB(GPIO0)  is  flashing.why they  are  different?  because  firmware is different?

1、I didn't  plug SSD ，I have got  such RS232 results,but  my computer can‘t  recognize  USB device。and  Flash Burner can‘t  recognize  USB device

    Hello Shuai,

    After reviewing the schematics you shared via email, I have the following observations:

    1) Since you are not using the USB SuperSpeed terminals of the TUSB9261, those terminals should be left unconnected (open), pulling those terminals to GND is NOT recommended (as per your schematics).

    2) If you are using a crystal (please remember that we highly recommend to use a 40MHz crystal), the GND terminals of the crystal must be connected to the VSSOSC terminal of the TUSB9261 instead of Board's GND.

    3. Since you are not swapping the SATA lines on your design, you must use the the SATA_NO_POLARITY_SWAP firmware (as it appears you are doing). On the other hand, the TUSB9261 Demo Board has the SATA TX pair swapped, so default firmware must be used for the Demo board, since default FW takes in account the TX swapping.
    Please let me know if you have any questions or comments. Also, please apply my recommendations and let me know your results.

    Best Regards,

    Alexis Cortes.

    Hello Alexis,

    Thank you for your reply .

    I have changed my schematics as  you said.

    the main point is this tip:

    1) Since you are not using the USB SuperSpeed terminals of the TUSB9261, those terminals should be left unconnected (open), pulling those terminals to GND is NOT recommended (as per your schematics).

    when I remove these C  and R.  left USB 3.0  unconnected  .my  computer found the USB2.0  device.and then it can  read  and write the SSD.

    You have helped  me  solve this  problem .thank you very much !thank  you !

    Best Regards,

    shuai.
