Hello Sho,
The Firmware file we provide on the TUSB9261 product folder is only the binary resulting from compiling the firmware source code.
As describen in the TUSB926x Flash Burner User's Guide, the device needs additional data to be programmed (USB descriptors, data identifiers and checksums).
That data is automatically added and programmed when using the TUSB926x FlashBurner GUI, however that same tool can also generate a full image that includes all the necessary data for those cases when you are using an external flash programming tool.
For details on how to do that, please check the TUSB926x FlashBurner User's Guide at section 4.8 - "Exporting the Firmware Data to a File"
Please click the green button if this answered your question.
Regards,
Jorge
Hello Orobianco,
The FlashBurner GUI doesn't have a feature to display the calculated checksum
Please note that two different checksums are generated and programmed into the SPI flash. There is one checksum for the USB descriptors section, and another checksum for the firmware data.
You can check the generated binary file to review the checksum values.
Please review section 3.1 at the TUSB926x FlashBurner User's Guide for details on the location of the checksums.
Regards,
Jorge
