SPI NAND flash 0x00000000 address to the SRAM inside the CPU and
execute it. FIRSTBOOT’s role is to initialize SDRAM memory, SPI NAND ,
and copy EBOOT, the second-level user booting code from the NAND Flash
0x00020000 address to SDRAM on the SBC6300X main board and execute
it; FIRSTBOOT also copies the Logo from the NAND flash 0x00080000
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.
2.3 The Flash Address of System Image Files
2.3.1 When booted from DataFlash
If you choose to boot from Data flash:
 FIRSTBOOT is located at the beginning of the 0x00000000 address
of SPI DataFlash, the capacity of FIRSTBOOT is 4KB;
 EBOOT is located at the beginning of the 0x00005000 address of
SPI DataFlash, the capacity of EBOOT is 200KB;
 The Logo is saved at the beginning of the 0x00100000 address of
SPI DataFlash;
 WinCE system image files NK is located in NAND flash in an area of
40MB starting from the 0x00200000 address.
The area in NAND flash outside of this 40MB will provide functionality as a
NAND flash hard disk under the WinCE system. Therefore, users can
customize a WinCE system of no more than 40MB. If you need to store a
WinCE system bigger than 40MB or need reduce the NAND flash partition
reserved for WinCE system images, please feel free to contact our
technicians for assistance.
