| =Boot Options=
| | *[[IMX8/Nitrogen8M/Overview|Overview]] section that summarizes the key hardware features and board connectors layout. |
| The board is able to boot from more that one way, below you will see how to configure the boot device.
| | *[[IMX8/Nitrogen8M/Getting Started|Getting Started]] section that provides a starting point for the i.MX Boundary Devices Nitrogen8M. |
| == eMMC ==
| | *[[IMX8/Nitrogen8M/Yocto|Yocto Support]] section to provide the build steps for Yocto distributions. |
| By default, the board will boot from eMMC.
| | *[[IMX8/Nitrogen8M/Android|Android Support]] section to provide the build steps for Android distributions. |
| Just be sure that the '''Boot Mode Switch''' is place on left side before connecting the power adapter.
| | *[[IMX8/Nitrogen8M/System_Recovery|System Recovery]] section that provides steps when the Nitrogen8M is not booting. |
|
| |
|
| == USB Boot ==
| | <noinclude>{{IMX8/Foot|iMX8MEVK/System Recovery|Nitrogen8M/Overview}}</noinclude> |
| This Boot option requires a Bootable USB stick and a Serial Console Cable, refer to iMX8 Software Support section to download a prebuilt image or create your own image with the instructions provided in the Custom Image section.
| |
| | |
| Instructions to setting up the USB Boot:
| |
| * Connect the Nitrogen8m to a host machine with the Serial Console Cable.
| |
| * Start any serial console (i.e minicom or term)
| |
| * Power on the board, the console will display the U-boot start-up screen.
| |
| * Press any key on your keyboard to stop the boot sequence, this will display the U-Boot console.
| |
| * Change the Boot Device with the following command:
| |
| <pre>
| |
| setenv boot_targets usb0
| |
| </pre>
| |
| * If you do not want to repeat this commands, you can save the selected Boot Device with this command:
| |
| <pre>
| |
| saveenv
| |
| </pre>
| |
| * Continue the Boot sequence by typing the next command:
| |
| <pre>
| |
| boot
| |
| </pre>
| |
| | |
| After the previous instructions, the board will boot from the USB stick
| |
| | |
| =Custom Image=
| |
| In order to create your own image, a supported Software Development Kit will be required for your desired OS.
| |
| | |
| ==Yocto==
| |
| To create a customized image with Yocto, first install its required packages with the following commands:
| |
| * repo tool
| |
| <pre>
| |
| mkdir ~/bin
| |
| curl http://commondatastorage.googleapis.com/git-repo-downloads/repo > ~/bin/repo
| |
| chmod a+x ~/bin/repo
| |
| export PATH=~/bin:$PATH
| |
| </pre>
| |
| | |
| * Yocto dependencies
| |
| <pre>
| |
| sudo apt-get install gawk wget git-core diffstat unzip texinfo gcc-multilib build-essential \
| |
| chrpath socat cpio python python3 python3-pip python3-pexpect xz-utils debianutils iputils-ping \
