12.7 NAND Flash Boot
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 “Valid Image Detection” on page 79 for more information on Valid Image
Detection.
12.7.1 Supported NAND Flash Devices
Any 8 or 16-bit NAND Flash devices.
12.8 SD Card Boot
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.
12.9 EEPROM Boot
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 “Valid Image Detection” on page 79 for more information on Valid Image
Detection.
