- \section1 Updating a Nexus 7 (2012) with \B2Q Images
-
- \note It is important that you repeat the steps in this section after you
- update \SDK.
-
- To update an unlocked Nexus 7 device with a \B2Q image:
-
- \list 1
- \li Make sure that the device is in \e{fastboot} mode and that it is
- connected to the development host via USB.
-

- \note You must install proprietary drivers for the Nexus 7 to boot
- correctly. Until then, the screen will briefly show the "Google" logo and then go black,
- instead of showing the \B2Q welcome screen or demo.
-

- current \B2Q image.
-
- To install the drivers to Nexus 7:
-
- \list 1
- \li Power on the device and connect it to the development host via USB.
- Also check that the device is \e{not} in fastboot mode.

+ \badcode
+ cd <INSTALL_DIR>
+ sudo Boot2Qt-3.x/apalis-imx6-eLinux/images/deploy.sh /dev/<device_name>
+ \endcode
+
+ By default, the Toradex Apalis iMX6 boots from its internal eMMC. In order to boot from
+ the external SD card, the U-Boot environment needs to be updated. Connect a serial cable
+ to the device and enter into the U-Boot environment by pressing any key before the autoboot.
+ Enter following lines into U-Boot:
+
+ \badcode
+ setenv bootcmd 'run sdboot ; echo sdboot failed ; run emmcboot ; echo ; echo emmcboot failed ; run nfsboot ; echo ; echo nfsboot failed ; usb start ;setenv stdout serial,vga ; setenv stdin serial,usbkbd'

+ setenv sdargs 'ip=off root=/dev/mmcblk1p2 rw,noatime rootfstype=ext3 rootwait'
+ saveenv
+ \endcode
+
