How to use the Trucrux SD card creation script #
This utility is provided on an “AS IS” basis. This is the script we use to create our recovery SD card with Android images. For machines with Android support, it is part of a larger script we use to create our recovery SD card, which also includes Android. It is a good example of using the output of the Yocto build to create a bootable SD card and use it to flash the target NAND flash/eMMC.
Note:
Before running this script you need a Yocto Image. To Build Yocto Image follow Building Yocto OS from the Source Code document.
Once the Yocto Image is complete, Run the below commands to create a symbolic link from Yocto to Android scripts
– Assuming your yocto and android are built under the following paths
Yocto Base DIR: ~/trux-fsl-yocto
Android Base DIR : ~/trux_imx-android-11.0.0_2.5.0
$ cd <Yocto Base DIR>
$ export YOCTO_BSP_BUILD = <Yocto Base DIR>
$ export ANDROID_BSP_BUILD = <Android Base DIR>/android_build
$ ln -sf ${ANDROID_BSP_BUILD}/device/trucrux/scripts/sh/trux_mk_yocto_sdcard/trux-create-yocto-sdcard-with-android.sh ${YOCTO_BSP_BUILD}/sources/meta-trucrux/scripts/trux_mk_yocto_sdcard/trux-create-yocto-sdcard-with-android.sh
$ ln -sf ${ANDROID_BSP_BUILD}/device/trucrux/scripts/sh/trux_mk_yocto_sdcard/trucrux_scripts/mx8_install_android.sh ${YOCTO_BSP_BUILD}/sources/meta-trucrux/scripts/trux_mk_yocto_sdcard/trucrux_scripts/mx8_install_android.sh
For creating an SDcard with only Yocto: #
Usage: sudo MACHINE=imx8mq-trux-q01 sources/meta-trucrux/scripts/trux_mk_yocto_sdcard/trux-create-yocto-sdcard.sh [options] /dev/sdX (Change /dev/sdX to your device name)
options: -h Display help message -s Only show partition sizes to be written, without actually write them -a Automatically set the rootfs partition size to fill the SD card -r Select alternative rootfs for recovery images (default: build_x11/tmp/deploy/images/trux-som-mx6/fsl-image-gui-trux-som-mx6.*)
If you don’t use the ‘-a’ option, a default rootfs size of 3700MiB will be used.
The ‘-r’ option allows you to create a bootable SD card with an alternative image for the installation to NAND flash or eMMC.
Example: “-r tmp/deploy/images/trux-som-mx6/fsl-image-qt5-trux-som-mx6” — selects the “Qt5 image with X11” recovery image
Once the script is done, use the SD card to boot, and then to flash your internal storage/s either use the icons,
or the following linux shell script:
install_yocto.sh
For creating an SDcard with Yocto + Android: #
Usage: sudo MACHINE=imx8mq-trux-q01 sources/meta-trucrux/scripts/trux_mk_yocto_sdcard/trux-create-yocto-sdcard-with-android.sh [options] /dev/sdX (Change /dev/sdX to your device name)
options: -h Display help message -s Only show partition sizes to be written, without actually write them -a Automatically set the rootfs partition size to fill the SD card -r Select alternative rootfs for recovery images (default: build_x11/tmp/deploy/images/trux-som-mx6/fsl-image-gui-trux-som-mx6.*)
If you don’t use the ‘-a’ option, a default rootfs size of 3700MiB will be used.
The ‘-r’ option allows you to create a bootable SD card with an alternative image for the installation to NAND flash or eMMC.
Example: “-r tmp/deploy/images/trux-som-mx6/fsl-image-qt5-trux-som-mx6” — selects the “Qt5 image with X11” recovery image
Once the script is done, use the SD card to boot, and then to flash your internal storage/s either use the icons(imx6/imx7),
or the following linux shell script:
install_android.sh
