Please note that if you purchased the iMX6D version and want to burn the device tree version image, please use the iMX6D device tree version CD (iMX6D also has a non-device tree version CD)

If you purchased the iMX6Q version and want to burn the device tree version image, please use the iMX6Q device tree version CD (iMX6Q also has a non-device tree version CD)

Where "MfgTool2.exe" is the burning tool, "cfg.ini" is the configuration file, open "cfg.ini", as shown in the following figure, make sure that the parameter of "[LIST]" is Ubuntu.

The compiled device tree Ubuntu16.04 image is located in the "06 image _ Ubuntu file system" directory of the imx6D/Q/PLUS device tree kernel CD material. It is divided into 1G and 2G images, and users use the corresponding images according to the size of hardware memory.

Here, take the 1G memory image as an example, and compare the "u-boot.imx", "zImage",

"iMX6_ubuntu.tgz" and the rest of "topeet_XXX.dtb" are copied to the burning tool.

Under the "mfgtools\ Profiles\ Linux\ OS Firmware\ files\ ubuntu" directory.

Be sure to perform this step first! Otherwise, the software will report an error when you open the burning tool.

The dialing switch setting of the development board refers to "2.2.1 startup mode setting (dialing switch)" setting to USB burning mode.

Type, connect the otg line, power up the development board. Finally, open the MfgTool2.exe tool in the "mfgtools" directory, such as

If it is a win10 system, it should be run in compatibility mode, as shown in the following figure.

As shown in the following figure, the burning is complete, click "Stop", and then turn off the burning tool "MfgTool2.exe".

If the development board is powered off, refer to the section "2.2.1 Startup Mode setting (Dial switch)" and set the development board to eMMC

Start the mode, power up the development board, and then refer to the section "2.2.2 uboot mode" to enter uboot mode, as shown in the following figure.

Set system parameters: in the uboot command line, use the command "setenv bootsystem ubuntu" to set the environment variable parameter to "qt" startup mode, and then use "saveenv" to save, as shown in the following figure.

After the setup is complete, use the "reset" command to restart the development board. After the development board starts, it is the Ubuntu16.04 system.

At this point, the study on "how to burn and write the Ubuntu system of the device tree kernel" is over. I hope to be able to solve your doubts.
