Hi Sriram,

Yes, Beagleboard-X15 is using device tree files to describe its specific hardware components. All Beagleboard-X15 DTS files are compiled into single DTB file.

In TI PSDK, Beagleboard-X15 fiels are located in:

{PSDK}/board-support/linux-kernel/arch/arm/boot/dts/

am57xx-beagle-x15.dts
am57xx-beagle-x15-common.dtsi

Pavel

Hi Sriram,

In this forum, AM57x TI PSDK is supported (Arago Linux distribution):

software-dl.ti.com/.../index_FDS.html

In TI PSDK, we do NOT support Device Tree Overlay (dtbo). See also below e2e threads:

linux-4.14.40/arch/arm/boot/dts/ti/am57xx-evm.its
linux-4.14.40/arch/arm/boot/dts/ti/dra71-evm.its
