For SPI flash for CX3 boot, we plan to use Winbond SPI flash. As a result of referencing KBA221833, the commands used are the same. However, there is only one difference.
Regarding "Sector Erase: D8h", D8h is Block Erase (64KB) in Winbond products (command to Erase 64KB area).
Furthermore, 4KB is called Sector, and 32KB and 64KB are called Block.
So, Each company may call Block or Sector differently,
But, is there any problem using Winbond SPI flash mentioned above for CX3?
