-Prepare for Reflash Device 
---------------------
-=serial console=
-  at the back of Ben Nanonote, there is "GND", "TXD" and "RXD", 
-  you can get serial output from those pins 
-  you need a TTL <-> RS232 converter. because the Ben Nanonote serial 
-  console is TTL. here[1] is the serial PIN in the board.
-
-=toolchain=
-    $ git clone git://github.com/lindnermarek/openwrt-x-burst.git[2]
-    $ git checkout --track -b x-burst origin/x-burst
-    $ make menuconfig
-         (select 'XBurst JZ47x0 [2.6]' in 'Target System')
-    $ make
-  then you will get toolchain under /PATH/TO/openwrt-x-burst/staging_dir/
-  toolchain-mipsel_gcc-4.1.2_uClibc-0.9.30.1/usr/bin
-
-=xburst-tools (usbboot tools)=
-  you can get source code at git://github.com/xiangfu/xburst-tools.git[3]
-    $ cd /PATH/TO/xburst-tools/usbboot
-    $ ./autogen.sh && ./configure && make && sudo make install
-  then you got the 'usbboot' command. that is for the reflash.
-
-=u-boot=
-  in openWRT menuconfig-->Target Images-->Build U-Boot bootloader -->
-  U-Boot target board (NEW) --> input 'qi_lb60
-  
-  here[4] is the u-boot github URL
-    $ make qi_lb60_config
-    $ make 
-  there is 'u-boot-nand.bin' is for Ben
-
-
-How To Reflash
---------------------
-1. plug the Ben to your computer. direct connect. no usb hub.
-2. short the two pin ('boot from usb' show in [1])
-3. press 'RESET' at the back of Ben
-4. in you computer run [5] and [6]. then you flashed the bootloader and kernel
-   to nand flash. 
-5. rootfs: format your SD card. 
-   the first partition must VFAT and others is EXT2.
-   we can put the kernel(uImage) in the first partition. put the rootfs in second partition.
-   uncompress openwrt rootfs to second partition of SD card
-6. now you can boot your Ben.
