SD Card Boot
NAND Flash Boot
Boot ROM does not support high-capacity SDCards.
The SD Card Boot program searches for a valid application in the SD Card memory.
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 NAND Flash Boot program searches for a valid application in the NAND Flash memory. If a
valid application is found, this application is loaded into internal SRAM and executed by branch-
