Description
Flow Diagram
The Boot Program integrates different programs permitting download and/or upload into the
different memories of the product.
First, it initializes the Debug Unit serial port (DBGU) and the USB Device Port.
SAM-BA
DBGU serial port.
The Boot Program implements the algorithm shown in
