To run dfu-util, you need to have /proc/bus/usb mounted and working.  The terminal command "ls /proc/bus/usb" should return something similar to, "001  002  003  004  005  devices", it shouldn't be empty. If it is empty, use this command:
+
See [[Manuals/Dfu-util]]
 
+
<pre>
+
sudo mount -t usbfs usbfs /proc/bus/usb
+
</pre>
+
 
+
You can permanently add it in your fstab so that it automatically mounts. You can use emacs to edit you fstab using the command "sudo emacs /etc/fstab -nw" in your terminal window. Add the below line to your fstab:
+
 
+
<pre>
+
usbfs  /proc/bus/usb  usbfs  defaults
+
</pre>
+
 
+
 
+
=== Before using dfu-util ===
+
You'll need to boot your phone into the NOR Boot Menu:
+
* Ensure your phone is connected directly to the host computer by USB (not the USB-charger! :)
+
* Ensure that you execute all dfu-util commands as root
+
* Power off the phone
+
* Hold down AUX
+
* Press POWER and hold it
+
* Release AUX, hold POWER until you see the menu
+
* Connect your Neo to your computer directly (Using a hub in between could cause problems with the hub and the usb reset)

Note: Some myth existed that dfu-util is not worked with sudo. This is not true of course. It is working from both sudo and su sessions. --[[User:Gena2x|Gena2x]] 12:30, 20 July 2010 (UTC)

=== Flashing the bootloader ===

dfu-util -a u-boot -R -D /path/to/u-boot.bin
+
 
+
=== Flashing the splash image ===

+
 
+
=== Copying a kernel into RAM ===
+
 
+
dfu-util -a 0 -R -D /path/to/uImage
+
 
+
Once this has finished, the kernel will be available at the default load address of 0x32000000 in Neo1973 RAM.
+
 
+
{{note|You cannot transfer more than 2MB of data into RAM using this method}}
+
 
+
== Troubleshooting notes ==
+
 
+
If during flashing of an image using dfu-util you're consistently getting an error -110 message, check that the size of the destination NAND [[Partitions|partition]] is big enough to hold the image.  For example the kernel partition is only 2 MB big by default and a kernel with debugging info compiled-in can often exceed this.  It's possible to change the partition layout to enlarge a given partition and shrink other partitions but you have to remember to reflash all partitions whose start offset has changed afterwards.  To adjust partitions layout use the ''mtdparts'' [[Bootloader|u-boot command]].
+
 
+
If in turn you're facing errors in seemingly random places during the flashing of images, most likely the USB hub or cable through which your Neo1973 is connected, is of too poor quality.  It is recommended that you always connect the phone directly to the host when using dfu-util.
+
 
+
If dfu-util reports a message like the following, before it starts flashing:<pre>
+
Resetting USB...
+
not at least 2 device changes found ?!?
+
Lost device after RESET?</pre> retry the command - it should work on a second run.
+
 
+
If dfu-util complains about not being able to program the device while in runtime mode, do the following: while in the boot menu, remove the usb cable and insert it again. Depending on the version of uBoot it should display somewhere in the menu that it is now in DFU mode. Now dfu-util should be able to continue.
+
 
+
If dfu-util is too slow on Windows, that's a known bug. A suggestion is to run Linux on a virtual box. An full root image 97MB that is 776Mbit, the USB 1.1 on the Neo FreeRunner is capable of either 1.5 Mbit/s (Low-Speed) and 12 Mbit/s (Full-Speed). So flashing it should take less than 9 minutes with low speed and a bit more than a minute with full-speed. Plus transfer overhead, plus decompression on the Neo side.
+
 
+
Note that any error messages indicate a probable failed transfer, despite latter messages emitted about success, etc.

Revision as of 22:32, 10 August 2010


dfu-util is a program that implements the Host (PC) side of the USB DFU (Universal Serial Bus Device Firmware Upgrade) protocol.

In the Openmoko project, we use this program to communicate with our specially enhanced bootloader, which implements the DFU device side.

Using dfu-util and your smartphone, you can

  • transfer and flash partitions in internal NAND Flash.
  • transfer anything into RAM
    • this can be used for fast development cycles of low-level code such as kernels without flashing them
  • read out the current internal NAND partitions
    • this is an easy and efficient way of doing full backups of your phone

Source Code

On Debian and Ubuntu, you'll need libusb-dev: sudo apt-get install libusb-dev autogen pkg-config autotools-dev autoconf automake

On Fedora you'll need libusb-devel and libusb-static: yum install libusb-devel libusb-static

On Gentoo you can: emerge -va openmoko-dfu-util

You can check out and build the latest version of dfu-util using the following subversion commands:
svn co https://svn.openmoko.org/trunk/src/host/dfu-util/
cd dfu-util
./autogen.sh
./configure
make

The resulting binary is dfu-util/src/dfu-util.

Binaries

Binary packages will be made available as part of the regular Openmoko builds. Currently, there is a dfu-util for Linux/i386.

You need to make the downloaded file (dfu-util) executable with:

chmod +x dfu-util

you can then run it with

./dfu-util
