pico-imx6ul support - wrong device tree

[Admdebian]

I'm building an image for my pico-imx6ul. The result is an image running without the right device tree.

For example, the board can't load any wifi card.

This is my build configuration:

    Build Configuration:
    BB_VERSION           = "1.36.0"
    BUILD_SYS            = "x86_64-linux"

    TUNE_FEATURES        = "arm armv7ve vfp neon callconvention-hard cortexa7"
    TARGET_FPU           = "hard"

    meta-edm-bsp-release = "added-wifi-drivers:10f5373fedd09c19ffb1a393272e3f3ed83b643a"

At the moment I use dd to flash the content of this archive:

    core-image-base-pico-imx6ul.sdcard.bz2

u-boot is using this device tree:

    imx6ul-pico-qca_pi.dts

But I want this one:

    imx6ul-pico_pi.dtb

Should I use a new Yocto version to correct this?
