Hi,
Where can I find the example for the dynamic Loading of the device
tree and its corresponding device driver.
How can I build the dts with or without the kernel source.
I am getting this error whenever I am trying to build the below sample
dts file using the dtc compiler.
dtc -O dtb -o leds-ns2.dtb leds-ns2.dts
Error: leds-ns2.dts:1.1-2 syntax error
FATAL ERROR: Unable to parse input tree
Below is the content of the leds-ns2.dts
#include <dt-bindings/leds/leds-ns2.h>
ns2-leds {
compatible = "lacie,ns2-leds";
blue-sata {
label = "ns2:blue:sata";
slow-gpio = <&gpio0 29 0>;
cmd-gpio = <&gpio0 30 0>;
modes-map = <NS_V2_LED_OFF 0 1
NS_V2_LED_ON 1 0
NS_V2_LED_ON 0 0
NS_V2_LED_SATA 1 1>;
};
};
Thanks,
R

That is an error at line 1, columns 1-2. dtc does not understand cpp
directives, you need to process leds-ns2.dts with cpp. The Linux
build infrastructure does this for .dtb targets in makefiles.

make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- <name of the dtb file>.dtb
This compiles fine.
