| - | You can enable R&D mode by passing the <code>--enable-rd-mode</code> flag to the [[Documentation/Maemo 5 Developer Guide/Development Environment/Maemo Flasher-3.5|flasher]].
| + | {{midgard_article}} |
| | | | |
| - | Note: This flag does not need to be passed to the EMMC image if you are flashing that as well.
| + | You can enable the R&D mode by passing the "--enable-rd-mode" to flasher. |
| | | | |
| - | You must use a Linux or a Mac OS X computer to enable R&D Mode, as the Windows update wizard will not allow you to enable/disable R&D Mode. Although, the Windows flasher will disable R&D Mode if you use it to reflash a device that has R&D Mode already enabled.
| + | When R&D mode is enabled |
| | | | |
| - | To switch back to production mode, use <code>--disable-rd-mode</code>.
| + | you can use sudo gainroot to get a root shell on the device |
| | | | |
| - | == What R&D mode does ==
| + | the power button turns the device on instantly (usually you have to keep it pressed for a while) |
| | | | |
| - | *<code>sudo gainroot</code> in the console can be used, without installing anything [[root access|extra]], to gain a root shell.
| + | you can enable some R&D mode flags (flasher --set-rd-flags) for various features: |
| | | | |
| - | *The power button turns on the tablet with a shortpress press as opposed to the longpress normally required.
| + | "no-lifeguard-reset" disables the lifeguard process (lifeguard reboots the device when an important system process crashes) |
| | | | |
| - | *[[Nokia N900|N900]]: The keyboard backlight behind the left and right side of the keyboard flickers in response to system activity.
| + | "serial-console" enables the serial console (the serial port pins are next to the battery) and causes a shorter battery life |
| | | | |
| - | == R&D mode flags ==
| + | "no-omap-wd" ??? |
| | | | |
| - | You can enable some R&D mode flags (<code>flasher-3.5 --set-rd-flags=''<flag>''</code>) for various features:
| + | "no-retu-wd" ??? |
| | | | |
| - | *<code>no-omap-wd</code> - Disables the watchdog on the OMAP processor.
| + | "no-usb-timeout" ??? |
| - | *<code>no-retu-wd</code> - Disables the watchdog on retu.
| + | |
| - | *<code>no-lifeguard-reset</code> - Disables the lifeguard process (lifeguard reboots the device when an important system process crashes).
| + | |
| - | *<code>serial-console</code> - Enables the serial console (the serial port pins are next to the battery) and causes a shorter battery life.
| + | |
| - | *<code>no-usb-timeout</code> - Unknown
| + | |
| - | *<code>sti-console</code> - Unknown
| + | |
| - | *<code>no-charging</code> - Disables charging via the USB port. bme will still be running in the background.
| + | |
| - | *<code>force-power-key</code> - Omap bootreason will be always pwr_key. Maemo system will not see any reboots or watchdog resets. Instead Maemo will think that device was started by power key.
| + | |
| - | | + | |
| - | running the command without parameters gives a list of available modes:
| + | |
| - | <code>flasher-3.5 --set-rd-flags</code>
| + | |
| - | | + | |
| - | <pre>
| + | |
| - | maemo_flasher-3.5_2.4.5.3_beta/flasher-3.5 --set-rd-flag
| + | |
| - | flasher v2.4.5 (Jun 25 2009)
| + | |
| - | | + | |
| - | Possible R&D flags:
| + | |
| - | no-omap-wd
| + | |
| - | no-ext-wd
| + | |
| - | no-lifeguard-reset
| + | |
| - | serial-console
| + | |
| - | no-usb-timeout
| + | |
| - | sti-console
| + | |
| - | no-charging
| + | |
| - | force-power-key
| + | |
| - | </pre>
| + | |
| - | | + | |
| - | It seems enabling of R&D mode is causing device ([[N900]]) to power up on battery insert and USB-connect.
