Documentation/Maemo Flasher-3.5 Tutorial/Usage

= Usage =

The Maemo Flasher-3.5 tool is a command line utility that supports N900 device with Fremantle 5.x platform releases and N800, N810 and N810 WiMAX Edition devices with Maemo Diablo 4.1.x platform releases.

Maemo Flasher-3.5 tool is run from a Linux, Windows or Mac OS X host computer as a command line tool, and it sends data and commands to the connected Maemo device via USB.

Among other purposes, Maemo Flasher-3.5 tool can be used to:


 * flash a Maemo device with a Diablo or Fremantle FIASCO image
 * flash a Maemo device (N900 only) internal memory card with an eMMC image
 * unpack a FIASCO image into separate parts like kernel and rootfs images
 * flash unpacked kernel or rootfs images to the Maemo device separately
 * change a Maemo device to R&amp;D mode and back to normal mode
 * set and clear R&amp;D flags for a Maemo device when in R&amp;D mode
 * boot a Maemo device with additional kernel startup parameters

All command line parameters supported by Maemo Flasher-3.5 tool together with some basic usage examples are documented in the Help.txt file available as part of the tool installation package. Maemo Flasher-3.5 tool binary gives command line help if it is run without any parameter or with  or   parameters.

= Setting Maemo device to flashing mode =

Before flashing a Maemo device with a FIASCO image, it is recommended to firstly set the Maemo device into flashing mode. When you attempt to flash the Maemo device, it tries to enable flashing mode on the fly, in which case setting the device to flashing mode explicitly is not required, but there have been reports that with some host PCs this does not work, see chapters  and .

For Nokia N800 and N810 with a Diablo image, flashing mode can be enabled by following these steps:


 * 1) Switch off the Maemo device (and do not use a charger).
 * 2) Attach a USB cable to the Maemo device and computer.
 * 3) Switch on the Maemo device while holding down the Home (N800) or Swap (N810) hardware button.

For Nokia N900 with a Fremantle image, flashing mode can be enabled by following these steps:


 * 1) Switch off the Maemo device.
 * 2) Press and hold down the 'u' key.
 * 3) Connect a USB cable between the Maemo device and host PC while holding down the 'u' key.
 * 4) When the USB cable is connected, it powers the Maemo device and sets it to flashing mode.
 * 5) When the USB icon appears in the upper right-hand corner, the Maemo device is in flashing mode.
 * 6) Release the 'u' key.

If performed correctly, the USB image is visible in the upper right-hand corner of the screen.

The Maemo device waits indefinitely for Flasher-3.5 input when it is in flashing mode. If flashing is tried without first setting the Maemo device to flashing mode, image flashing may fail if the Maemo device is not able to change to the flashing mode automatically.

= Usage examples =

To get a list of supported command line options, run:

If you wish to perform commands other than image flashing, then omit the  option as rebooting the Maemo device may reset the given configuration change back to normal.

To enable R&amp;D mode for Maemo device, run:

To warm flash an image to the Maemo device, run:

Replace &lt;FIASCO image&gt; with the the firmware image you downloaded from Nokia. This flashes a FIASCO image to your Maemo device and reboots the device after it is completed (at which point you can unplug the USB). The procedure is the same for all other image flashing components (for example, separate kernel, rootfs and eMMC images), see the option list for details.

To print out Maemo device product code and product hardware revision, run:

To cold flash (needed usually when the bootloader has been changed), run:

The code  used in the example is the product code for the N900 device. The  is the product hardware revision, which is a 4-digit code. Both product code and hardware revision can be found from the type label of the device to be flashed. The type label is on the back of the device, underneath the battery.

To flash a kernel with separate kernel image, run:

To flash just a part of the whole FIASCO image (for example, only rootfs), run:

This flashes only the rootfs from the &lt;FIASCO image&gt; and reboot the device.

To access to the individual parts of the FIASCO image, run:

which expands &lt;FIASCO image&gt; to your current directory.

= Tips and Troubleshooting =


 * If you get a "Permission denied" error, then make sure you have execution rights to the Flasher-3.5 binary executable.
 * You need to have administrator rights or run command with sudo in Linux if you get errors like this: Error claiming USB interface: Operation not permitted
 * It may help to connect the USB cable directly to the computer USB ports, avoiding the use of a hub. Using the USB ports in the back of a computer can also work better than using those in the front.
 * Flash always the FIASCO image first and after that the latest available eMMC image, if needed. The eMMC image does not need to be flashed every time when a new FIASCO image is flashed. Flashing the eMMC image also overwrites all data from the internal memory card.
 * If warm flashing fails, try to switch off the power from the Maemo device, remove the USB cable and try again from the beginning.
 * If cold flashing fails, try to warm flash the Maemo device first using the same FIASCO image. After that try cold flashing again.
 * If Maemo Flasher-3.5 is not supported on your operating system you can try to install Maemo SDK Virtual Image from Maemo Development Environment Downloads page and flash Maemo device from Virtual Image (which includes Ubuntu). This may or may not work for you depending on how well virtualization technology you use supports USB on your hardware.

= Known issues =

This is a list of known issues found from Maemo Flasher-3.5 final release.


 * Maemo Flasher-3.5 does not work with 64-bit operating systems. Workaround is to install Maemo SDK Virtual Image and run Maemo Flasher-3.5 from image.
 * Maemo Flasher-3.5 does not work with Mandriva 2010 distro because Flasher-3.5 is not able to locate the correct USB address and timeouts. Workaround is to install Maemo SDK Virtual Image and run Maemo Flasher-3.5 from image.
 * On Windows host PC if Nokia PC Suite has been installed to the environment once Windows has started also PC Suite starts running. If Nokia PC Suite is running when N900 is plugged in to the PC with USB cable and with the 'u' key held down, Nokia PC Suite gives an error message and Flasher-3.5 does not see the device. Workaround is to exit Nokia PC Suite before plugging in N900 with USB cable and starting Flasher-3.5.
