This package contains binary and guide to help you run a linux demo
on the Jz4750 APUS board. And the default nand is 4096k bytes per page.
Get more details from "linux_nand_flash_guide_CN.pdf" and "USB_Boot_Tool_Manual_1.4_CN.pdf"

Decompress apus-demo.rar, you can get next files:
* u-boot-nand.bin:             u-boot binary for booting from NAND
* uImage:                      linux-2.6.24.3 kernel image for APUS
* root.yaffs2:                 linux-2.6.24.3 demo root FS in YAFFS2 format

Please dowload USBBoot_1.4 at first
* usb_boot_v1.4:     USB boot tool for program nandflash


Now, follows next steps to run the demo

1. Install USB boot tool(For Apus-1.1.2): 
   Press SW6 when power on and reset board.
   Install the usbboot driver.
   Change into usb_boot_v1.4/tools and double click USBBoot.exe.

   *Copy USBBboot_APUS.cfg to USBBoot.cfg
   Then run command in USBBoot command line.

2. Program nand flash:

   Note: 1.If change USBBoot.cfg, run command "fconfig USBBoot.cfg 0 0" or
   	    reboot device with "boot 0" to make config active.
         2.If you want to have PC find the USB device, you should press button SW6 plus reset,
           loosen reset first and SW6 next.
(1) Boot device.

    USBboot :> boot 0

(2) Your are recommended to erase nand at first
    
    USBboot :> nerase 0 4096 0 0

(3) Program file, make sure ECCPOS is 24, BCHBIT is 8, SDRAM size is 64M.

    USBboot :> nprog 0 u-boot-nand-.bin 0 0 -n
    USBboot :> nprog 1024 uImage 0 0 -n
    USBboot :> nprog 2048 root.yaffs2 0 0 -o

    
(4) Starts a serial terminal on your host and sets to {57600bps/8-bit/1-stopbit/no-parity


    Now everything is ok and you can have you fun with shell terminal :-)
