Other Parts Discussed in Thread: TUSB9260

Tool/software: Linux

Team,

Customer use TI flash burner to programmer the SPI flash but couldn't boot up. Below is the message, would you please have a look and let us know if any comments?

usb 2-1: new high-speed USB device number 2 using musb-hdrc

usb 2-1: New USB device found, idVendor=0451, idProduct=926b

usb 2-1: New USB device strings: Mfr=1, Product=2, SerialNumber=3

usb 2-1: Product: TUSB9260 Boot Loader

usb 2-1: Manufacturer: Texas Instruments

usb 2-1: SerialNumber: TUSB9260BL01

usb 1-1: new high-speed USB device number 2 using musb-hdrc

In addition, there are 4 .bin files in the download FW package but they look the same. What are the differences? 

what does the TUSB926x Default Firmware U1/U2 Disable mean?

    Tried all .bin files but all failed. Also checked the SPI waveform from oscilloscope, communication looks stop at 2nd byte. Is there other workable FW can share for verification?

    Allan,

    The uses for the the other firmware is described in the readme.txt file:

    "The default firmware swaps the polarity of the SATA Tx signal pair per TI's reference board design. Depending on your particular board layout, you may require an alternate polarity setup for the SATA Tx and Rx signals. These firmware binaries are provided for that usage."

    I tried reproducing your problem in the lab, and I could not. I am using our TUSB926x Flash software with Windows 10; I am programming the firmware using the TUSB926x Demo board using USB. Could you tell me more about your setup?

    Hi Nicholaus,
    I applied one EVM and read the boot file from EVM EEPROM. It just works. Would you please check the SW at ti.com?

    Thanks.

    Allan,

    I don't understand.  I have checked the software at TI.com with an EVM and it works, and you also say that it works. Which software would you like to me to check? 

    Regards,
