MCUboot always boots from the primary slot and copies the image from the secondary slot into the primary slot when an upgrade is requested. The upgrade can be either overwrite-based or swap-based mode. In an overwrite-based upgrade, the image in the primary slot is lost and there is no ...
台式机这样的常规系统中,通常将引导装载程序装入主引导记录(Master Boot Record,MBR)中,在嵌入式设备中,通常将引导程序放置在不易丢失的存储器的开始地址或者是系统冷启动时PC寄存器的初始值。通常,在台式机或其他系统上,BIOS将控制移交给引导装载程序。而在嵌入式系统中,通常并没有像BIOS那样的固件程序(注,有的嵌...
