Is there a mode in default firm ver.1.06 to perform "Write" action from TUSB9261 to FLASH?

Currently, according to the TUSB9261 evaluation board, the logic of the WP pin is fixed to H,

but if there is concern about unexpected data corruption, fix the WP pin to L if there is no write operation. , I want to use

Hi,

The only way to write to the TUSB9261DEMO EVM flash is by using the FlashBurner Utility. This software uses a driver which causes the TUSB9261 to write to the Pm25LV512A flash. This process is explained in section 3.1 of the TUSB9260 Flash Burner - User Guide.

You are correct, the WP pin is fixed to "H" on our TUSB9261DEMO EVM. You will either have to physically modify the board or create your own to change it to "L". The EVM is meant for evaluation only.

Regards,
