Flat Devicetree

With BSP Revision 0109 the Linux kernel version changed from 3.16.7 to 4.1 The devicetree source & blob files for kernel 3.16.7 are not compatible to kernel 4.1 and vice versa.

BSP Rev. ≤ 0105

Naming convention

Device Tree Blobs
Several device tree blobs (.dtb files) are built by default, the resulting files are named as follows:
imx6<q|dl>-mba6x-<hdmi|lvds|multi|pd>.dtb
When building an sd card image, the HDMI enabled device tree blob is used by default.

Naming convention

Device Tree Blobs
Several device tree blobs (.dtb files) are built by default, the resulting files are named as follows:
imx6<q|dl>-mba6<a|b>-<hdmi|lvds|multi|pd>.dtb
When building an sd card image, the HDMI enabled device tree blob is used by default.

Flat Image Tree (FIT)
Additionaly a FIT image (*.itb) is generated, which contains all device trees in a single file.

To select an individual DTB from this FIT you have to set the U-Boot variables fdt_type and fitfdt_part accordingly.
