Hi Aleksandr,

Please try erasing the flash first in order to re-program the SPI Flash.

Hi,

Is it possible to disable the SPI flash momentarily through a enable pin on your system and then connect the TUSB9261 to the PC? Allowing the TUSB9261 boot device to connect (pre-firmware load) should allow you to re-program the connected SPI flash. Please be sure to re-enable the SPI flash before re-writing and be sure the the SPI flash is not write or read protected.
