Booting Essentials
This section of the product wiki contains guides to update and boot from different boot sources on the phyCORE-i.MX7 SOM.
Boot Modes
The bootloader, one of the key software components included in the BSP, completes the required hardware initialization to run operating system images. The boot mode determines the location of the primary bootloader and is selected from the S1 dipswitch on the underside of the Carrier Board.
Warning
The Boot Switch S1 should only be modified with the i.MX7 completely powered off and disconnected from a power supply.
