Compiling the Device Tree Binaries

Starting with the 3.8 kernel each TI evm has an unique device tree binary file required by the kernel. Therefore, you will need to build and install the correct dtb for the target device. All device tree files are located at arch/arm/boot/dts/. Below list various TI evms and the matching device tree file.

To build an individual device tree file find the name of the dts file for the board you are using and replace the .dts extension with .dtb. Then run the following command:

make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- <dt filename>.dtb

The compiled device tree file with be located in arch/arm/boot/dts.

For example, the Beaglebone Black device tree file is named am335x-boneblack.dts. To build the device tree binary you would run:

make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- am335x-boneblack.dtb
