When the dtb file is created from the various dtsi files, a temporary file is created that is the output of the compile of the dtb file.

I have seen this file before BUT cannot remember where the temporary file is located.

In imx6ull-colibri.dtsi there is

&uart1 {
	pinctrl-names = "default";
	pinctrl-0 = <&pinctrl_uart1 &pinctrl_uart1_ctrl1>;
	fsl,uart-has-rtscts;
	fsl,dte-mode;
};

In my board file (one to replace imx6ull-colibri-eval-v3.dtsi) how do i remove the

fsl,uart-has-rtscts;

line ?

I have done this is my file BUT the console stops working

&uart1 {
	pinctrl-names = "default";
	pinctrl-0 = <&pinctrl_uart1>;
	fsl,dte-mode;
	status = "okay";
};

HI @adrian

Thanks for writing to the Toradex Community!

I have seen this file before BUT cannot remember where the temporary file is located.

The file is located at the same place as the .dtb file.

In my board file (one to replace imx6ull-colibri-eval-v3.dtsi) how do i remove the line?

I don’t understand the question. You just delete it.

I have done this is my file BUT the console stops working

Did you check to disable the hardware flow control?

Best regards,

The file is located in the DTS folder but is set to be hidden ( This is why i did not find it !! )

I was under the belief that i could make changes in my board file and not change the supplied dtsi files ( imx6ull.dtsi & imx6ull-colibri.dtsi) This is not the case as my dtb file is generated from those two files and my board file, i had to make changes in ALL the files.

Nice, that you foudn .tmp files.

Yes, this is true and you should make the changes on the correct level (SoC, SoM or carrier Board).
