查看Freerunner的源代码 Freerunner 0

== 一、安装dfu-util ==

http://wiki.openmoko.org/wiki/Dfu-util

=== (一)ubuntu可用apt-get命令直接安装(版本较老) ===

=== (二)下载源码自己编译(版本较新) ===

编译dfu-util时提示:
<pre>
kaigo@kaigo-desktop:~/WD/fr/tools/dfu-util-0.7$ ./autogen.sh 
./autogen.sh: 2: autoreconf: not found
</pre>

解决：
 $:sudo apt-get install autoconf
或者按照openmoko wiki提示，直接安装下面这个软件(推荐)：
 $:sudo apt-get install libusb-dev autogen pkg-config autotools-dev autoconf automake 

=== (三)安装windows驱动 ===

windows驱动(使用虚拟机也是必不可少的)见 http://wiki.openmoko.org/wiki/Dfu-util-windows 中 Preparing to use dfu-util 一节里面推荐了 Jungo(需付费)或用[http://sourceforge.net/projects/libusb-win32/files/ LibUSB-Win32]为fr生成驱动文件：
<pre>
 Vendor ID  Product ID  Description
 0x1d50     0x5119      USB Device
</pre>



== 二、flashing freerunner ==

官方资料:

http://wiki.openmoko.org/wiki/Flashing_the_Neo_FreeRunner

=== (一)、下载img ===

如Om2009: http://downloads.openmoko.org/distro/testing/NeoFreerunner/

=== (二)、烧写img ===

1、按住AUX，再按住power直到出现uboot的菜单

2、连接usb线

3、执行烧写命令
  # Flash u-boot
  dfu-util -a u-boot -R -D /path/to/u-boot_image
  # Flash the kernel
  dfu-util -a kernel -R -D /path/to/uImage.bin
  # Flash the rootfs
  dfu-util -a rootfs -R -D /path/to/rootfs.jffs2

=== (三)、相关错误 ===
在虚拟机(xp下用virtualbox安装ubuntu)和windows运行：
 $dfu-util -a kernel -R -D uImage.bin
出错：
<pre>
Resetting USB...
not at least 2 device changes found ?!?
Lost device after RESET?
</pre>
http://wiki.openmoko.org/wiki/Manuals/Dfu-util中Troubleshooting notes一节列出了这类错误，让我们尝试重新插拔一下usb线，但尝试没有效果
后切换到ubuntu系统(如果没记错的话，应该就是切换了下系统:d)，再运行上述命令：
 $dfu-util -a kernel -R -D uImage.bin
提示错误：
<pre>

Opening DFU USB device... ID 1d50:5119
Claiming USB DFU Runtime Interface...
Cannot claim interface 2: could not claim interface 2: Operation not permitted
</pre>
最后一句让我怀疑是不是权限问题，以root执行：
 $ sudo dfu-util -a kernel -R -D uImage.bin
还是提示出错：
<pre>

dfu-util does currently only support DFU version 1.0

Opening DFU USB device... ID 1d50:5119
Claiming USB DFU Runtime Interface...
Cannot set alt interface: could not set alt intf 2/0: Protocol error
</pre>
就在这里卡了很久，在google搜索"could not set alt intf 2/0"发现这好像是libusb库里面的提示，由于当前dfu-util是使用apt-get直接安装的，难道是关联库有问题？?

于是再回到 [http://wiki.openmoko.org/wiki/Dfu-util Dfu-util]的页面，尝试编译使用上一节的方式重新编译dfu-util的源代码：
 dfu-util-0.7$ ./autogen.sh
提示：
<pre>
Can't exec "libtoolize": 没有那个文件或目录 at /usr/bin/autoreconf line 196.
Use of uninitialized value in pattern match (m//) at /usr/bin/autoreconf line 196.
autoreconf: Entering directory `.'
autoreconf: configure.ac: not using Gettext
...
</pre>
于是安装:
 $:sudo apt-get install libtool

再进行flashing, ok:
 $ sudo dfu-util -a kernel -R -D uImage.bin
<pre>
