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.

now we put the code in github.com
[3] in folder 'usbboot', here is the tar package and Debian package.

[master] is the last u-boot.
command: "mmc init;fatload mmc 0 0x80600000 uImage;bootm" is for boot the kernel in sd card.
