Upgrade the dtc on your host?
i just follow the steps refered in the website. and i want to know what 's the problem.
If you type “dtc --version” on your host, what will be show?
now i used command “sudo apt-get install device-tree-compiler” to install .“dtc --version” is DTC 14.5, then i make,i worked,but many warnings , i don’nt know whether it is something wrong.
It should be fine.
As @WayneWWW said, it should not matter. However, realize that the kernel source for every single kernel release also comes with dtc. There is a target, “make dtc” I think, which should build a version from that kernel source.
