TMS320F28377D: Serial Boot Mode: Method to program Flash without erasing specific sectors

Part Number: TMS320F28377D

 Hello,

I am currently trying to load firmware using the Serial Boot Mode.

However, I have some critical data stored in the internal Flash memory, so I need to program the new image without erasing specific sectors where this data is located.

It seems that the standard serial_flash_programmer utility performs a "Mass Erase" (erasing the entire Flash) by default, which makes it difficult for me to use in this situation.

Could you provide a method or guidance on how to avoid a full erase and preserve specific sectors during the serial boot loading process?

Best regards,
