    Hello Roberto,

    Many thanks your reply ~

    Two more questions:

    1.Does the default TUSB9261 F/W from TI website (.HEX and .BIN.)

       These are also for program machine used ? Or just for TI TUSB926x_Burner GUI tool ?

       If not for program machine , where I could get it for mass production ? TKS !

    2. TUSB926x_Burner GUI tool provide "Program"  and "Program full binary image"  What's the difference ?

    Hello Terry,

    The EEPROM requires a full binary image to works properly. this image contains the needed headers plus the firmware data. this full binary image can be generated using the TUSB926x_Burner GUI tool following the "4.8 Exporting the Firmware Data to a File" section of the tool User's guide. This Exported .bin or .hex file will contain all the required headers plus the firmware data in a single file and it is the file that you must use on a program machine.

    Regards,
    Roberto
