SAM9G10
Supported NAND Flash Devices
The NAND Flash Boot program searches for a valid application in the NAND Flash memory. The
first block must be guaranteed by the manufacturer. There is no ECC check.
If a valid application is found, this application is loaded into internal SRAM and executed by
branching at address 0x0000_0000 after remap. See
more information on Valid Image Detection.
8 or 16-bit NAND Flash Devices.
The SD Card Boot program searches for a valid application in the SD Card memory.
(Boot ROM does not support high capacity SDCards.)
It looks for a boot.bin file in the root directory of a FAT12/16/32 formatted SD Card. If a valid file
is found, this application is loaded into internal SRAM and executed by branching at address
0x0000_0000 after remap. This application may be the application code or a second-level
bootloader.
The EEPROM Boot program searches for a valid application in an EEPROM connected to the
TWI address: 0x0050_0000.
If a valid application is found, this application is loaded into internal SRAM and executed by
branching at address 0x0000_0000 after remap. See
more information on Valid Image Detection.
If no valid DataFlash device has been found during the DataFlash boot sequence, the SAM-BA
boot program is performed.
The SAM-BA boot principle is to:
– Wait for USB Device enumeration.
– In parallel, wait for character(s) received on the DBGU
– Once the communication interface is identified, the application runs in an infinite
loop waiting for different commands as in
