Colibri imx7d with Iris-v2 carrier board, Linux colibri-imx7-emmc-14989987 5.4.193-5.7.2+git.b60d3160fd04 #1 SMP Fri Dec 23 15:47:24 UTC 2022 armv7l armv7l armv7l GNU/Linux

Need help to enable the LVDS interface for LCD. I am trying to create a dtbo to enable the LVDS interface for my LCD. The LCD that I am using is the Innolux G101ICE. The following dts is virtually copied from colibri-imx7_parallel-rgb-lvds-rgb24-single_overlay.dts but it doesn’t seem to work at all. There is no backlight. I checked /sys/class/backlight and the link to the backlight driver isn’t there.

I have run out of ideas and don’t know what else to try. Please help.

Hi @macbum , can you please share G101ICE datasheet and the device tree overlays file? The booting log from the serial console is also helpful and paste it here as well. Thanks.

5

You can download it from here.

6

can you describe the wiring between the LCD display interface and X7 on Iris?

Is the LCD’s Pin4(data format) hardwired to high or low? Because both VESA and JEIDA have 6-bit format output.

9

It’s hardwired to 6-bit mode.

10

Please check the LCD cable. Is the LCD Pin4(Data format) unconnected or is it pulled up to 3.3V or down to GND?

11

It’s internally pulled to GND which means that it is hardwired to 6 bit mode.

Thanks for your confirmation. colibri-imx7_parallel-rgb-lvds-rgb24-single_overlay.dts for our upstream kernel. The log indicates that it is a downstream-based BSP installed on your Colibri iMX7. Please double check by cat /etc/os-release.

14

ID=tdx-xwayland
NAME=“TDX Wayland with XWayland”
VERSION=“5.7.2+build.21 (dunfell)”
VERSION_ID=5.7.2-build.21
PRETTY_NAME=“TDX Wayland with XWayland 5.7.2+build.21 (dunfell)”
DISTRO_CODENAME=“dunfell”

15

Ok. It is a downstream-based BSP installed. Please test colibri-imx7_lcd-lt170410_overlay.dtbo. It is a device tree overlay for our 10.1-inch LVDS display with a resolution of 1280*800.

16

Thanks. Can you point out which branch I can fetch the file from?

The branch I am working from is toradex_5.4.y

17

It is toradex_5.4-2.3.x-imx. Our default image also comes with device tree overlays binaries. Thay are located at /boot/overlays/. With that, you can give a quick test.

18

I don’t see it in the /boot/overlays directory of the stock image. I built it from the git repo and found it at the branch you stated. I tested it but it still does not seem to work or have any effect. I can build the dts file for the overlay with no problems, U-boot also loaded it with no problems. I will check the display hardware and perhaps try a different display.

19

please share the entire boot log from the serial console.
