We try to move our current projects from Apalis T30 to Apalis iMX6. We allready bring everything to run, but with display settings I have a question. We want to run a display over LVDS. I found the settings under https://developer.toradex.com/knowledge-base/display-driver-registry-settings. But the settings seems not have the same function like on T30.
On T30 I set following parameters in the registry:
What are the associated settings for the iMX6? I’m desperate, can you help? With the shown settings on T30 it is possible to use LVDS-Display and also HDMI output. Would that also possible on iMX6? Thanks a lot.
Hallo @alex.tx,
Thank you for the link, which I allready know, like I described in my post.
But I can´t bring it to run. I think I setup the timings correct, but it doesn´t run. Backlight is on, but I get no picture. Here are my settings.

And here is the spec from display.

Can you see, what I did wrong? HDMI is running fine. I setup that screen as clone and center the screen on full hd monitor.

At your T30 settings you have LvsdBitMode: 0 which means 24bpp *(BTW you have a typo there) but for iMX6 you set BPP t 32. Could you try to set it to 24 ? Do you have a scope? Can you check signals on LVDS lines? Looks like you have a single LVDS channel display. You can also try change OUT to 3.
According to display datasheet snippet you posted Hsync and Vsync should be disabled but i can’t see DisableSyncs 3 at your imx6 settings. Could you please avoid posting screenshots? It hard to read them. Please share your registry settings as text file. Just do an “export” at Regedit.
I can also recommend to set UseSplashSettings to 1 and play with display parameters at bootloader level. This way you can try different combination much faster.
Bpp is MainPanelBpp on T30 at documentation and that was set to 32. Also iMX6 support only 16 and 32 bpp in documentation. I tried 24 for Bpp, but then module is not starting any more.
What effects have the disable of Hsync and Vsync for the timings? Can I set hsw and vsw to zero, when I disable that settings and only use front an back porch? Do you have an example for DE mode?
I bring display to show the content. I made wrong settings at oep and pcp. I read that in wrong direction. Also the timing settings I changed. It seems that value for vertical total adress time in datasheet of vendor is wrong. I increased it to 845 lines and after that it shows a clear picture. Here are the settings from the registry (this time in text format ). The settings are for InnoLux G101ICE-L01.
