Hello all,
In linux kernel source, there are many .dts files (device tree source)
For example there is a file ./arch/arm64/boot/dts/arm/juno.dts.
To tried to make juno.dtb from juno.dts but I don't know how to do it.
(by the way, once I did make for the kernel build, junno.dtb file seems to
be generated in the same directory)
Just in case I want to make my own .dts and .dtb, I tried compling juno.dts
file. (I had installed dtc on my ubuntu 16.04 machine before)
$ dtc -I dts -O dtb -o juno.dtb arch/arm64/boot/dts/arm/juno.dts
Error: arch/arm64/boot/dts/arm/juno.dts:11.1-9 syntax error
FATAL ERROR: Unable to parse input tree
The dtc program cannot process the line below in the .dts file.(line 11)
#include <dt-bindings/interrupt-controller/arm-gic.h>
I don't know how I should let the preprocessing kick in.
I tried (because there is
include/dt-bindings/interrupt-controller/arm-gic.h)
$ dtc -i include -I dts -O dtb -o juno.dtb
arch/arm64/boot/dts/arm/juno.dts
But it doesn't work.
How can I use dtc program to make juno.dtb?
Or if I have to use Makefile, what is the command?
Thanks,
Chan Kim
