Hello,

Could you clarify your following statement: "I have duplicated the SPI flash from the demo board and solder the new one directly on my board without using the flash burner.
In this case, it does not stop the boot process but it does not work because of the inverted polarity in differential pair."

Also, can you try with the Firmware version available at http://www.ti.com/product/TUSB9261#technicaldocuments.

Regards.

Hello Elias,

I mean I have made a binary image from the demo board SPI flash and burn a new one with a flash programmer. In this case it works fine (except that I should invert polarity on one of the differential pair as the demo board).

I have tried with the firmware available at http://www.ti.com/product/TUSB9261#technicaldocuments, but I think I do not use the right parameters.

Regards,

PLR

Hello Pierre-Louis,

The flash burner will add some information to the binary code, so if you make an image of an already programmed memory and you use that binary code as the firmware to be burned on another memory then after the flash burner you will have a memory with duplicated descriptors information (see Figure 3-1 of the TUSB9260 Flash Burner - User Guide)

The HID and UAS command support is describe on the TUSB9260 Flash Burner - User Guide at the below link.

Hello Elias,

Is it possible to know what the parameters are for the demo board?

Thank you,

Regards,

Pierre-Louis

The default settings are HID Enabled, UAS Enabled and Self-powered Device.

You should also upgrade to the latest firmware (rev 98) available at http://www.ti.com/product/tusb9261#technicaldocuments
