TUSB9261: Settings when writing data to EEPROM using a method other than the FlashBurner GUI

Expert 8760 points
Part Number: TUSB9261

Hi team,

My customer wants to burn the EEPROM data using a method other than the FlashBurner GUI.
So the customer wants to know the following settings.

・Byte order :  big-endian / little-endian
・Data width :  8 / 16 / other
・First byte : D0~ / D8~ / other
・Surplus area : write 00  / write FF
・Check sum : byte sum / word sum / other
・Other necessary settings

Please let me know.

Best regards,
Fumio Nakano

  • Hello,
    These are the consideration you need to take care.

    ・Byte order :  little-endian
    ・Data width :  8
    ・First byte :  D7~D0
    ・Surplus area : write FF
    ・Check sum : byte sum, please note it is a CheckSum8 Modulo 256
    ・Other necessary settings: the Boot code will start to read from EEPROM address 0x00 and the first 2 bytes must be 0x60 0x92, this is the EEPROM image ID.

    Using  Flash Burner Gui you can generate an EEPROM image that you can burn using any other method, the 4.8 Exporting the Firmware Data to a File process is described in section 4.8 of the Tool User's Guide. http://www.ti.com/lit/ug/sllu125d/sllu125d.pdf
