Boot
The SAM-BA Boot is a default Boot Program which provides an easy way to program in-situ the
on-chip Flash memory.
The SAM-BA Boot Assistant supports serial communication via the DBGU or the USB Device
Port.
The SAM-BA Boot provides an interface with SAM-BA Graphic User Interface (GUI).
The SAM-BA Boot is in ROM and is mapped in Flash at address 0x0 when GPNVM bit 2 is set to
0.
The external memories are accessed through the External Bus Interface.
Refer to the memory map in
• Communication via the DBGU supports a wide range of crystals from 3 to 20 MHz via
• Communication via the USB Device Port is limited to an 18.432 MHz crystal.
