Compiling custom dtb from dts

vladimirovseych — Wed, 23 Dec 2015 08:10:31 GMT

Hello, Dear Community!

I'm trying to make my own device tree for custom board on imx287. I'm doing it according to this instruction: Device Tree — Wiren Board

But I catched errors, e.g.

root@vladimir-Ubuntu:/home/vladimir/Downloads/mydts/my# cat .TESTimx287.dtb.dts.tmp | grep -v "^#" | dtc -I dts -O dtb -o TESTimx287.dtb

Error: <stdin>:37.28-29 syntax error

FATAL ERROR: Unable to parse input tree

Has anybody some ideas? Maybe there are other ways to compile .dtb?

Thank you!

Hi,

likely you already solved, just check line 37

Typical errors in dts are :

- syntax errors as missing ";" at end of a block / line

- wrong entry name reference
