Flashing the Neo FreeRunner
From Openmoko
As Openmoko development continues, Openmoko regularly releases updated versions of the Openmoko root filesystem, the kernel, and the U-Boot. These may be programmed into the Flash memory of Neo FreeRunner. You can use the USB cable and Openmoko provided tool to flash Neo FreeRunner.
NOTE: The Openmoko software team builds images daily. If you want to use the latest images, you can download the image from the daily build, but we recommend you download the most stable image from http://downloads.openmoko.org/releases/Freerunner/. Images here have been tested by the test team.
See Latest Images for more information about the different images available. |
NOTE: If you have a working image that you're happy with but want to try something different, you should probably do a Pre-Flash Backup, although it looks like the method on that page may not entirely work. |

Download the DFU-util
from GNU/Linux
You can download the flashing tool for a GNU/Linux host from: http://downloads.openmoko.org/releases/Freerunner/dfu-util
On the GNU/Linux host you can use the following command to download the dfu-util:
wget http://downloads.openmoko.org/releases/Freerunner/dfu-util
Afterwards you have to change the rights on the file:
chmod a+x dfu-util
from Windows
You can download the flashing tool for a Windows host from: http://projects.openmoko.org/frs/?group_id=166&release_id=162 (see installation instructions at Dfu-util-windows)
Using dfu-util
Dfu-util will be used like this, to write an image file to a (predefined) "partition name" (referred to as Altsetting in dfu-util help/manual) :
./dfu-util -a (partion name) -R -D (download image file name)
NOTE: The meaning of the parameters you specified:
-a --alt alt : Specify the Altsetting of the DFU interface by name or by number |
Flashing the Kernel
The Neo FreeRunner needs to be at the NOR uBoot menu for flashing. For more information on booting, see booting the Neo Freerunner (in short: press and hold aux then power). Log into the NOR uBoot menu and just stay there, do not select or enter any item in menu. Now you will be able to flash, make backups of your Freerunner or query the Freerunner with dfu-util. Then, connect your Neo to the GNU/Linux or Windows host via USB cable. You can download the kernel from http://downloads.openmoko.org/releases/Freerunner/ from GNU/LinuxType in the following command in the terminal on a GNU/Linux host. On some systems you need to be root before this will work and on Ubuntu you must preface the command with "sudo" or you will get the following error: "Cannot claim interface: could not claim interface 2: Operation not permitted" sudo ./dfu-util -a kernel -R -D uImage-2.6.24+git20080424-om-gta02.bin from WindowsType in the following command in the console on a Windows host: dfu-util -a kernel -R -D uImage-2.6.24+git20080424-om-gta02.bin Press Enter to execute the command. When flashing succeeds the following will be shown: status(0) = No error condition is present Done! |

Flashing the Root Filesystem
You can download the root filesystem from: http://downloads.openmoko.org/releases/Freerunner/
from GNU/Linux
Type the following command in the terminal of a GNU/Linux host. On some systems you will need to be root.
./dfu-util -a rootfs -R -D openmoko-devel-image-fic-gta02.jffs2
from Windows
Type the following command in the console of a Windows host.
dfu-util -a rootfs -R -D openmoko-devel-image-fic-gta02.jffs2
When flashing succeeds the following will be shown:
status(0) = No error condition is present Done!
Flashing u-boot
dfu-util -a u-boot -R -D uboot-gta02v5-latest.bin
