2.2.1 Principles for booting the SBC6300X WinCE 6.0 system
from DataFlash
After power on, the system inside the CPU ROMBOOT will
automatically copy the FIRSTBOOT image (the first-level user booting
code) from the SPI DataFlash 0x00000000 address to the SRAM inside
the CPU and execute it. FIRSTBOOT’s role is to initialize SDRAM
memory, SPI DataFlash, and copy EBOOT, the second-level user booting
code from the SPI DataFlash 0x00005000 address to SDRAM on the
SBC6300X main board and execute it; FIRSTBOOT also copies the Logo
from the SPI DataFlash 0x00100000 address of the SBC6300X main
board to SDRAM. In its default state, EBOOT will automatically copy the
WinCE system image NK from the NAND flash 0x00200000 address to
the SDRAM on the SBC6300X main board, and hand over system control
to the operating system. In addition, EBOOT undertakes the
management operations of the underlying hardware and shares the data
settings with the operating system.
