Binary packages will be [http://downloads.openmoko.org/releases/Om2008.8-update/dfu-util 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:
 +
<pre>
 +
chmod +x dfu-util
 +
</pre>
 +
you can then run it with
 +
<pre>
 +
./dfu-util

[http://packages.debian.org/dfu-util dfu-util is packaged] for Debian ''>= lenny'', so can be installed with: <tt>apt-get install dfu-util</tt>
 +
 +
[http://sourceforge.net/projects/slackfr-packs/ dfu-util is packaged] for '''Slackware''' (12.1), so can be installed with: <tt>pkgtool</tt>
 +

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:
 +
 +
<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>
 +
 +
 +
=== Avant d'utiliser dfu-util ===
 +
You'll need to boot your phone into the NAND 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 until the Boot Menu appears

 +
 +
{{note|You cannot transfer more than 2MB of data into RAM using this method}}
 +
 +
== Notes de mise à jour ==
 +
 +
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 [[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.

--list

Using the --list option, you can list the available DFU capable devices, their configuration, interface and altsettings. Below is an example for a current Neo1973 phone in u-boot Runtime Mode

# ./dfu-util --list
dfu-util - (C) 2007 by Openmoko Inc.
This program is Free Software and has ABSOLUTELY NO WARRANTY

Found DFU Runtime: [0x1457:0x5119] devnum=0, cfg=0, intf=2, alt=0, name="USB Device Firmware Upgrade"

Below is an example for a current Neo1973 phone in u-boot DFU Mode

# ./dfu-util --list
dfu-util - (C) 2007 by Openmoko Inc.
This program is Free Software and has ABSOLUTELY NO WARRANTY

Found DFU: [0x1457:0x5119] devnum=16, cfg=0, intf=0, alt=0, name="RAM 0x32000000"
Found DFU: [0x1457:0x5119] devnum=16, cfg=0, intf=0, alt=1, name="u-boot"
Found DFU: [0x1457:0x5119] devnum=16, cfg=0, intf=0, alt=2, name="u-boot_env"
Found DFU: [0x1457:0x5119] devnum=16, cfg=0, intf=0, alt=3, name="kernel"
Found DFU: [0x1457:0x5119] devnum=16, cfg=0, intf=0, alt=4, name="splash"
Found DFU: [0x1457:0x5119] devnum=16, cfg=0, intf=0, alt=5, name="rootfs"

This shows you six interfaces, all in configuration 0 and interface 0, with altsetting 0...5, for RAM and each partition.

--device

You can specify the USB Vendor and Product ID of the device you want to program:

dfu-util --device 0x1457:0x5119

If you only have one standards-compliant DFU device attached to your PC, this is optional. However, as soon as you have multiple DFU devices, dfu-util will detect this and abort, asking you to specify which device it shall use.

--transfer-size

Specifies the size of each individual USB transfer. If you don't use it, the maximum possible size for your combination of host operating system and USB device is chosen (for optimal performance).

--download

download the given file into the device.

--upload

upload from the DFU device into the given file[name].

NOTE: Upload support is currently broken - #676


Commandes fréquemment utilisées

Pour l'instant, il n'y a pas de manuel à proprement parler. Mais vous pouvez utiliser les quelques exemples suivants :

Mettre à jour le rootfs

dfu-util -a rootfs -R -D /path/to/openmoko-devel-image.jffs2

Mettre à jour le noyau

dfu-util -a kernel -R -D /path/to/uImage

Mettre à jour le gestionnaire de démarrage

dfu-util -a u-boot -R -D /path/to/u-boot.bin

Mettre à jour l'image affichée au démarrage

dfu-util -a u-splash -R -D /path/to/splash.gz

see also Configuring_the_boot_splash_screens

Copier un noyau dans la 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


Notes de mise à jour

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 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 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:
Resetting USB...
not at least 2 device changes found ?!?
Lost device after RESET?
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.
