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

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