3.1.3 AIS NOR Boot
When METHOD==0x2, the AIS NOR boot option will be executed. When booting with this method, the bootloader expects the AIS image to start from address 0x60000004, which is mapped to NOR Flash.
Figure 3. Placement of AIS for NOR Boot The AIS boot method is described in detail later in this document.
