 For Inforce IFC6410,  you can run the following command:
 
-bc. sudo fastboot boot boot-qcom-apq8064-ifc6410-qcom-snapdragon-##VERSION##.img -c "console=ttyMSM0,115200n8 root=/dev/mmcblk0p13 rootwait rw"

 For  eInfochips ERAGON600, you can run the following command:
 
-bc. sudo fastboot boot boot-qcom-apq8064-eI_ERAGON600-qcom-snapdragon-##VERSION##.img -c "console=ttyMSM0,115200n8 root=/dev/mmcblk0p13 rootwait rw"

 Finally, if you want to make the bootargs change persistent, you can modify the released boot image and reflash it into the @boot@ partition:

 * The serial/uart driver does not support high speed transfer, and is limited to 115200 speed. Since UART is used between the on-boart Bluetooth devices and the SoC, this limits the bandwidth between Bluetooth device and the Snapdragon 600. Some use cases such as Bluetooth audio cannot work properly at such low speed. Some other use cases such as data transfer will work but slower than expected. Suppport for high speed UART is being implemented, and will be released in a future release.
 * In the Gnome login manager, 2 fallback sessions are proposed: using Metacity or Compiz. Compiz is not working, and there is no plan to fix that, as Compiz is obsolete. Metacity is working fine, and provides an alternative graphical interface that does not use GPU for composition.
 * Few software codecs are installed by default; you might install additional codecs such as  @gstreamer1.0-plugins-bad@ or @gstreamer1.0-plugins-ugly@.
-* Once you have flashed the boot partition with a valid boot image, the board will automatically boot that image when powered on. To avoid automatically booting you can jumper the board as explained in this "page":http://mydragonboard.org/2013/forcing-ifc6410-into-fastboot/ for IFC6410. To boot the ERAGON600 board in fastboot mode, please refer @section 7.4.2 Fastboot mode@ on @Software Reference Manual@ at "eInfochips support centre":http://www.supportcenter.einfochips.com/. If you cannot use this method and still needs to reboot into fastboot mode, you can erase the boot partition on a running target using the following command @sudo cat /dev/zero > /dev/mmcblk0p7@
