Hi,

Is there any way, that we could update the DTB directly, without recompiling/reflashing the whole kernel image?

As of now, each and every small device-tree modification requires whole kernel rebuild and reflash, which takes a long time.

Do you have any option to update the DTB alone?

let me double check and get back to you.

Hi vinuchandran,

It is confirmed that the kernel has to be rebuilt with device tree change. Because the platform build is for unbuntu, and not for Android, no DTB parition for unbutun,and device tree are built into kernel image

Thanks
