•
Strap the boot signals to the desired levels at POR to configure the required boot mode for your application (i.e.
using a DIP switch). This is required on the carrier board to override the default boot mode set on the SOM. Refer
to section
•
Implement a serial debug port (such as via UART0) to interface with the module for development.
•
Implement a reset button for easy reset of the module.
4.7 Solder Jumpers
For configuration purposes the phyCORE-AM64xx SOM has several solder jumpers.

provides a functional summary of the solder jumpers which can be changed to adapt the phyCORE-AM64xx
SOM to specific design needs. It shows their default positions, possible alternative positions, type, and functions. The
jumpers are a 0402 package size with a 1/16W
or higher power rating.
