Device Tree Overlay 24-bit IMX6DL

jaimeibk · October 31, 2019, 4:24pm

Hello,

I need some help to get a device tree overlay working. I have a TFT-Display that is wired as 24-bits, instead of the usual 18-bit Toradex used. I get the idea that I have to modifiy the pinmuxing for the extra 6 bits in the device tree, so I gave it a try by using an Overlay.

/dts-v1/;
/plugin/;

/ {
	compatible = "toradex,colibri_imx6dl", "fsl, imx6dl";
	fragment@0 {
		   target-path = <&iomuxc>;
		   __overlay__{
				ipu1{
					pinctrl_ipu1_lcd: ipu1grp-lcd {
						fsl,pins = <
				MX6QDL_PAD_DI0_DISP_CLK__IPU1_DI0_DISP_CLK 0xa1

				>;
					};
				};
			};
		};
};

I am getting a syntax error that I can not figure out and another one “Unable to parse input tree”.

Any and all help will be deeply appreciated.

Greetings @jaimeibk,

The issue is that the pin names are defined in imx6dl-pinfunc.h, which should be located in the torizon/arm32v7-debian-dev-tools container at /device-tree-overlays/dts-arm32/imx6dl-pinfunc.h. You’ll want this to be in the same directory as your overlay file when you try to compile it.

You’ll also need this include statement in your overlay file: #include "imx6dl-pinfunc.h"

Example:

/dts-v1/;
/plugin/;

#include "imx6dl-pinfunc.h"

With these changes I was able to compile your overlay. I hope this helps resolve your issue.

Best Regards,
Jeremias

Hi, Jeremias!

I am still struggling. It keeps sending me a syntax error that I cannot figure out when trying to compile. I am already on the same directory as the imx6dl-pinfunc.h file. Do you see anything strange?

Hi, Jeremias

I am still getting an odd syntax error. I am already in the same directory as the .h file with the pin definitions though.

Do you see anything odd?

jeremias.tx · October 31, 2019, 9:52pm

Does the error message specify a particular line?

jaimeibk · October 31, 2019, 10:03pm

jeremias.tx · October 31, 2019, 10:16pm

I believe the error is the include statement can you switch it from /include/ to #include.

jaimeibk · October 31, 2019, 10:32pm

I just changed it. Still failing, though.
Here’s the output again:

What command are you running to compile? For reference here’s my overlay:

And here’s the command I run to compile:

root@93291e2107aa:~# dtconf build --no-git-repo ./custom.dts

Successfully built device tree

jaimeibk · October 31, 2019, 11:18pm

I was using dtconf -b file.dts.

I just got your command to work. I am not sure why was that not working.

Compilation was successful. I then enabled the overlay, rebooted, and nothing is working anymore. I cannot ssh to it.

Any clues?

jeremias.tx · October 31, 2019, 11:41pm

You need to have the “–no-git-repo” argument when working on a custom made overlay otherwise dtconf will look to where the toradex provided overlays are stored.

Finally as for your other issue while it does seem you are pinmuxing the right pins. What I assume is happening is that you’re allocating pins to this new pinctrl group that are already being used by other interfaces, which can cause things to work unpredictably.

In short you’ll need to create overlays that disable these conflicting interfaces to free the pins you want to use. Do take caution in what interfaces you are disabling as you may need some of these depending on your end purpose, which may require some shuffling of pins.

Also make sure to always use “dtconf validate” before you enable an overlay to make sure it is compatible with the overall device tree.

jaimeibk · November 1, 2019, 8:00pm

That was definitely what happened!! I had to disable weim, which was using the pins, to free them before enabling the pins for the display.

Thank you!!

jeremias.tx · November 1, 2019, 9:13pm

No problem, glad we were able to work through your issue.

jeremias.tx · November 4, 2019, 11:38pm

This overlay file compiled for me. Did you make sure you’re using the --no-git-repo option?

The command should look like: dtconf build --no-git-repo ./custom.dts

jaimeibk · December 6, 2019, 3:25am

Hi, Jeremias

I have some follow-up on this issue. It worked with your last advice. I discovered another issue, though. When I activate the overlay and run dmesg, I get the following, much of which is in red (maybe warning only?):

The previous step I took was to disable weim on another overlay. I get no messages of that sort when I do activate that one, so I am sure it happens when I activate this overlay. I am concerned that this may cause malfunctioning ahead.

Got any ideas?

jaimeibk · December 6, 2019, 3:25am

Hi, Jeremias

I discovered that when enabling this overlay, dmesg returns a lot of warning messages that I did not get beforehand. It all points out to the iomuxc section, as if I broke something else there.

Here is the dump of the messages:
