Hello all ,

I want to SDIO Pin as GPIO. I have done change in imx6ul-14x14-evk.dts file but how to compile it to form a new imx6ul-14x14-evk.dtc and load it in board.

i have following How to compile the Device Tree Source Code 

but in  <build dir>/tmp/workshared/imx6ulevk/kernel-source/script/

$ ./scripts/dtc/dtc -I dts -O dtb -o ./file_name.dtb <path>/file-name.dts

as my dtc folder does not contain any output file for compile dts file .

 I am this getting error

$ ./scripts/dtc/dtc -I dts -O dtb -o ./file_name.dtb <path>/file-name.dts

$ BASH :  dtc/dtc folder not found

$ ./scripts/dtc/dtc.c -I dts -O dtb -o ./file_name.dtb <path>/file-name.dts

Hi Sachin,

You can also use make. Here is an example:

$ cd ~/fsl_release_bsp_3.14.52/build-qt5-imx6qsabresd/tmp/workshared/imx6qsabresd/kernel-source/
$ export ARCH=arm
$ export CROSS_COMPILE=arm-linux-gnueabihf-
$ make imx_v7_defconfig
$ make imx6q-udoo-hdmi.dtb

And the file will be generated inside ~/fsl_release_bsp_3.14.52/build-qt5-imx6qsabresd/tmp/workshared/imx6qsabresd/kernel-source/arch/arm/boot/dts
