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. |
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
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)
The Neo FreeRunner needs to be at the NOR uBoot menu for flashing. For more information on booting, see booting the Neo Freerunner. Log into the NOR uBoot menu and select Set console to USB. /Just stay in NOR uBoot menu to be able to connect via dfu-util. If selected and entered "Set console to USB", then dfu-util was unable to connect./ 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/ 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" ./dfu-util -a (partion name) -R -D (download image file name) or: sudo ./dfu-util -a kernel -R -D uImage-2.6.24+git20080424-om-gta02.bin 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! |
