imx6 Device Tree compilation -- FATAL ERROR: Unable to 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 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.

Solution

  • You can use the Makefile file provided with the kernel source to handle all the issues for you.

    From the kernel code root directory, simply run:

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

    Just make sure to replace the CROSS_COMPILE value with the right prefix.
