TUSB9261: TUSB9261 SPI flash

Part Number: TUSB9261

Hi,

I have build up an USB-SATA Interface with SPI flash of Mircochip: SST25VF512A . It will be flashed by the TI Windows Flash Burner tool. But the firmware doesn't start. The TUSB9261 is still in bootloader mode. Does it depend on the internal unchangeable bootloader software inside the TUSB9261 or depends it on the Firmware 1.05 or 1.06?

  • Hi Bjoern,

    Please confirm that the SST25VF512A is connected as shown in the TUSB9261 USB 3.0 to SATA Bridge datasheet in section 8.2.2.4 and that the SST25VF512A meets all the specifications described in that section.  Figure 3 shows a schematic of how it should be connected.

    The bootloader for the TUSB9261 is stored on ROM inside the TUSB9261; the firmware should be stored on the SST25VF512A.  Assuming you have followed the steps described in the TUSB926x Flash Burner User Guide and successfully loaded the firmware onto the SST25VF512A , the bootloader will retrieve the firmware from the SPI Flash on startup.
