Custom Device Tree Blob Target

danielbujak — Thu, 13 Jul 2017 14:49:03 GMT

Hi All,

When I build the images for my custom board based on the imx6ul, I still get a imx6ul-14x14-evk.dtb file generated. I'd like to change the target to create a imx6ul-customboard.dtb and be able to modify the source files to match my board layout. I think I should create a copy of all the imx6ul-14x14-*.dts files and rename them imx6ul-customboard-*.dts and then modify those to meet my needs. However, I'm unsure where in the build configs I should be specifying which device tree source to build into the image. Do I just set the BR2_LINUX_KERNEL_INTREE_DTS_NAME?

Is there any device tree customization guide available, or can anyone point me in the right direction?

Thanks!

Hi danielbujak,

Device tree is an extensive topic. The following document explains how to customize a device tree. In this case the Udoo board is used.

For general information about device Tree you may take a look to the links provided at the end of this post:
