Linux – imx6 Device Tree compilation — FATAL ERROR: Unable to parse input tree

device-treeembeddedlinux

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 are:-

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

The kernel version that I am using is linux-3.18.5 and dtc version is DTC 1.4.0.

Device tree sources in the kernel deviate from the regular syntax, by using the cpp preprocessor for includes and substitution. This proceeds 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
