正常情况下Flash Bank0位于低地址区域,FlashBank1位于高地址区域。正常启动时CPU从Bank0低地址区域开始执行程序,如图16所示。 在IAP流程中,如果判断待升级程序容量小于一个Bank容量,则可以使用这种快速在线升级方法,Boot-loader IAP程序放在Flash Bank0,将用户程序USER APP程序写入Flash Bank1中,然后写入更新标志位(标志...

NOR Flash烧写原理在对FLASH进行写操作的时候,每个BIT可以通过编程由1变为0,但不可以有0修改为1。为了保证写操作的正确性,在执行写操作前,都要执行擦除操作。擦除操作会把FLASH的一个SECTOR,一个BANK或是整片FLASH的值全修改为0xFF。在写的时候要注意每个页、扇区、块的边界问题。 对Flash读写操作流程(W25Q64...
