Imx6 Compiling device tree - FATAL ERROR: cannot parse input tree

I am working on Embedded Linux for TX6U-8010 based on Freescale imx6.

I am trying to compile dtb using the device tree compiler (dtc). However, when I use the command:

dtc -O dtb -o imx6dl-tx6u-801x.dtb imx6dl-tx6u-801x.dts

... I get the following error:

 Error: imx6dl-tx6u-801x.dts:13.1-9 syntax error FATAL ERROR: Unable to parse input tree

Lines 12, 13, 14: -

 /dts-v1/; #include "imx6dl.dtsi" #include "imx6qdl-tx6.dtsi"

The kernel version I'm using is linux-3.18.5, and the dtc version is DTC 1.4.0.

You can use the Makefile supplied with the kernel source to handle all problems.

In the root directory of the kernel code, simply run:

 make ARCH=arm CROSS_COMPILE=arm-none-eabi- imx_v6_v7_defconfig make ARCH=arm CROSS_COMPILE=arm-none-eabi- dtbs

Just replace the CROSS_COMPILE value CROSS_COMPILE the right prefix.

The sources of the device tree in the kernel deviate from the usual syntax, using the cpp preprocessor to enable and replace. This happens as follows:

 IDE=<your-device-name> SRC=$IDE.dts TMP=$IDE.tmp.dts DST=$IDE.dtb cpp -nostdinc -I include -undef -x assembler-with-cpp $SRC > $TMP dtc -O dtb -b 0 -o $DST $TMP rm $TMP
