Byte Padding

Postby fastbike » Mon Jun 07, 2021 12:06 am

I'm looking to program an SPI flash chip (Winbond ‎W25Q80DLZPIG).

The vendor of the image to be uploaded specifies to set byte padding value of “00” (the default padding value used by SPI is “FF”).

Does your software support this configuration ?

FLASH memory cells are by default 0xFF (empty) but you can rewrite it with any value. You will need to prepare your file before writing to FLASH. You can modify buffer to 0x00 and write it to FLASH and you will have 0x00. In REVELPROG-IS software you can use fill function and select all area or selection area and set it to 0x00:
