did you load backlight-gpio module?
Please supply me a your config file, dmesg and env print from uboot.
(I renamed imx6q-udoo-15lvds.dtb to imx6q-udoo.dtb. Also, instead of uImage in your instructions, I named it zImage.) envPrint.txt
did you test Xorg server with /dev/fb2 for vivante? and please paste lsmod.
I have seen that you use imx6q-udoo.dtb in uboot. Did you copy imx6q-udoo-15lvds.dtb to imx6q-udoo.dtb ?
I copied imx6q-udoo-15lvds.dtb to imx6q-udoo.dtb.
Also, if I try compiling and installing the other UDOO kernel repository: https://github.com/UDOOboard/linux_kernel I get some output on the LVDS display (the penguin and a glitched prompt) but USB, and a lot of other drivers don't work.
could you test it with Xorg server and dev/fb2 ? Probably you have default graphic output on /dev/fb0 so you have to remove from command line support for hdmi and from kernel or change output to /dev/fb2. Usually I don't use output from console on dev/fb2, only from Xorg server.
I currently don't have Xorg installed, so do you know how could I output just the console to the LVDS screen?
try remove from kernel hdmi support and configure only LVDS in kernel command line.
could you test it ftp://ftp.embeddedarm.com/ts-arm-sbc/ts-7350-linux/samples/bmptoraw.c with /dev/fb2 ?
When I test bmptoraw.c with /dev/fb2, I get "cat: write error: No such device" when I do the command "cat image.raw > /dev/fb2" as root.
I just recompiled the kernel with:
CONFIG_FB_MXC_HDMI=n
CONFIG_SND_SOC_IMX_HDMI=n
but I'm still getting the same problem.
Does this look okay?

backlight looks ok, I'll try change dtsi files with next release.
I tested it with my udoo. Howto show console on 7inch screen:
dmesg | grep -i command [ 0.000000] Kernel command line: console=ttymxc1,115200 root=/dev/sda1 rw fec.disable_giga=1 mem=1024M video=mxcfb0:dev=ldb,LDB-WVGA,if=RGB666,bpp=32 panic=10

Xorg works too.
In your command line I found: video=mxcfb1:dev=ldb,DB-WXGA,if=RGB24,bpp=32
"DB-WXGA" - probably typo, or try LDB-WVGA "RGB24" - try RGB666 "mxcfb1" - try mxcfb0
regards,
I still have nothing on my screen (below is output of dmesg | grep -i command):
[alarm@alarm ~]$ dmesg | grep -i command
[ 0.000000] Kernel command line: console=ttymxc1,115200,115200 root=/dev/mmcblk0p1 rw rootwait fbmem=24M video=mxcfb0:dev=ldb,LDB-WVGA,if=RGB666,bpp=32
I got the other parameters from this page: http://elinux.org/UDOO_setup_lvds_panels
I don't have any possibility to reproduce problem because I don't have a 15 inch panel.
Okay.
Have you confirmed that the seven inch panel works with the latest Arch Linux ARM distribution and your kernel? http://archlinuxarm.org/platforms/armv7/freescale/udoo
That way I can hopefully narrow down this issue and verify if this is an issue with the kernel or something with the Arch Linux ARM distribution/uboot.
Yes, I use arch linux on my udoo quad and 7inch panel, and it works.
btw. you use kernel with 5.0.11.33433(p7.1/3), please remember that you have to update you userland packages. With arch linux you could try branch use 5.0.11 p4.4.
my packages: imx-gpu-viv-g2d 5.0.11.p7.1-1 imx-gpu-viv-g2d-samples 5.0.11.p7.1-1 imx-gpu-viv-samples 5.0.11.p7.1-1 imx-gpu-viv-x11 5.0.11.p7.1-1 xf86-video-imx-viv 3.10.53_1.1.0-1
btw. I don't support legacy vivante 4.x.xx driver.
Okay, thanks for the help! I'll probably keep messing with it.
By the way, I just got the linux_kernel working lvds working with Arch from the other repo: https://github.com/UDOOboard/linux_kernel
The text is kind of glitched on the screen making it hard to read, but it appears to be working :)
Okay, fixed the glitched text by changing the kernel command line arguments.
Did you test 4.x too ?
Not yet, I'm using their 3.14 branch. I'll have to try some of the other kernels out once I get Xorg to work somehow (encountering some annoying driver errors). Ideally, I'd like to just have some sort of patch that I could apply to the Arch Linux ARM PKGBUILD or make a PKGBUILD of this kernel that would enable LVDS/other features, so I could be always be using the latest/greatest kernel with the features I want.
Could you test 4.x with dts file from 3.14 and try run LVDS ? I'll do that. :)
I tried to compile the 4.4 kernel, and the build fails -- I get "fatal error: uapi/linux/oom.h: No such file or directory."
Also, I think it would be helpful if you provided a suggested config file that you use for your repo.
could you share whole log? I dont know why but there is a file:
ls include/uapi/linux/oom.h include/uapi/linux/oom.h
Could you check your local repo ?
Hi, please pull repo and execute: make udoo_quad_defconfig, then compile kernel 4.4.x
It looks like a problem with IPU. I have to updated it and then we will make new tests.
I just compiled and installed 4.4 and have only the backlight again.
Hi, Could you change resolution in a dts file from 1366x768 to 1360x768. It should work. Vpeter suggested it.
I think the black bar on the side could potentially annoy me too much to permanently switch, but I'll give it a try.
Okay, just tried it and still getting same problem.

Gave that a shot but still had no luck.
vpeter4: could you test the kernel ?
The problem is that I only have openelec running and using two vivante versions (3.10.17-1.0.2 and 5.0.11.p4.5). For this kernel I would need to adjust whole build environment.
Can someone post bootable sd card image which I could try? And replace only dtb/kernel with mine.
Hi, Could you test kernel 4.2 with 5.0.11.p4.4 ?
btw. I'll make branch 4.4 with 4.5 too. :)
Sorry but I'm not familiar with Arch and which packages needs to install. When I'm done with debugging my systemd boot problem I have I will build my image with this kernel and required libraries. But can't tell any eta. Sorry. Only quick tests are possible for me to do right now.
No problem. By the way, that Arch installation instructions should build a system that drops you into a console where you can just log into with username: alarm and password: alarm. It may already have all the packages included that you need to test the kernel, but it's been a few months so I don't remember.
Hi, could you check branch 4.4-5.0.11.p7.3. I updated IPU driver.
I compiled/installed and my kernel hanged at usbcore.
4.4-5.0.11.p7.3 branch ? :> strange.
YEs, I could confirm that. Its a problem with mmc.
I was working on getting my 15 inch LVDS panel compatible with the latest version of Arch Linux ARM a few months ago, and finally got a chance to work on it again recently.
I followed your directions to make, build, and install the kernel with the configuration file udoo_quad_defconfig. I am booting from imx6q-udoo-15lvds.dtb with the updated Image.
Everything appears to be working fine (connected through serial). However, I am only getting the backlight on my 15 inch panel--no penguin or prompt to login.
Is there anything that jumps out to you that I am missing? Do I need to configure any command arguments before the kernel boots? Am I missing something in my config file?
Thanks so much for doing this repo and for the help!
