DTS support in imagebuilder

When using imagebuilder, the make scripts don't rebuild the kernel images in buildir/target-/linux--.

This means that updating DTS files has to be done by rebuilding the whole of openwrt/kernel. Is there an easier fix?

Kind regards

No,you gotta rebuild the kernel for that.
And for that you gotta build from source

In previous versions (Chaos Calmer) it did rebuild the dtb in image builder, and all the tools to rebuild the dtb seems to be still included in imagebuilder. Is there a specific reason that this behaviour changed?

I really like YOLO solutions. As the most of the image builder process is doing everything I want the only thing I needed was to update the DTB.

make image PROFILE=rt5350f-olinuxino FILES=files/ PACKAGES="kmod-usb-storage block-mount kmod-fs-ext4"


cp ${ORIGVMLINUX} ${ORIGVMLINUX}-olinuxino-rt5350f

When you need a DTB files, just use fdtdump and edit as you like.
The advantage is that I don't have to modify my kernel and I do not have to recompile everything for every time. Exactly as DTB files are intended.
