Booting Essentials

This section of the product wiki contains guides to update and boot from different boot sources on the phyCORE-AM64x SOM.

Boot Modes

The phyCORE-AM64x development kit supports booting from many different interfaces. By default, the developement kit is set to boot from the micro-SD card. To change the boot device, DIP switches S3 and S4 can be used. Boot switches should be changed with power off.
