Yocto add DTB to machine

Contributor III

Hi all,

I'm trying to add a new dtb to my Yocto machine, adding

KERNEL_DEVICETREE = "imx6sx-sdb.dtb imx6sx-sdb-emmc.dtb imx6sx-sdb-m4.dtb imx6sx-sdb-pf3000-ldo.dtb"

The new dtb is imx6sx-sdb-pf3000-ldo.dtb

I added my dts file to linux kernel and it compiles well. .dtb is created.

When I try to bitbake fsl-image-mfgtool-initramfs recipe the do_install step fails with the following error:

NOTE: make -j 4 imx6sx-sdb.dtb

For me it looks like the kernel recipe is not updated when it is used during mfgtools image.

Can you, please, share how did you add the .dts file to the kernel?
