Re: [beagleboard] Re: BBB 24-bit LCD using device tree

okay i tried it and unfortunately it didn't work , all pin from 27-46 were on mux 0 mode which they should be to get lcd working . i think there should be some configuration i need to do in some file. anyone have any idea about that? what should i do apart from just setting pins??? And yeah i did

Re: [beagleboard] Re: BBB 24-bit LCD using device tree

yeah looks kind a that way , i am actually confused if HDMI is already plug and play then it means HDMI chip is also getting input and that input is my tft lcd requires what if i directly applies that to my tft lcd will it gonna work ? On Sun, Jul 16, 2017 at 11:17 PM, Dennis Lee Bieber

hey, i am currently working on BBB rev C and i want to interface 16 bit(565 RGB) parallel LCD with the board. how should i configure my BBB to get it working? i know something about device tree overlay but i haven't found any proper documentation on how to work with LCDs. it would be great if

[beagleboard] Re: BBB 24-bit LCD using device tree

Thanks for the pointer David. I'd reviewed that before, but hadn't noticed the extra steps at the bottom. Unfortunately, those still don't get 24 bit video going (per fbset). So, I'm still wondering if anyone knows if the tilcdc in 3.8.13-bone50 kernel is supporting 24 bit modes, or if I

[beagleboard] Re: BBB 24-bit LCD using device tree

Is this still true? Looking in the source (from http://lxr.free-electrons.com/source/drivers/gpu/drm/tilcdc/tilcdc_crtc.c) I see that it supports bpp=24 if (priv-rev == 2), so I'm hoping that this has been corrected. I'm using the tilcdc in the 3.8.13-bone50 kernel from the Debian

I based it off the LCD4 dt. It I am reading this right, it uses the tilcdc driver. The LCD4 is supposed to be a 24-bit panel, but they are connecting it at 18-bit. Where can I find a list of lcd drivers built in? I've had to resort to reading the code to firgure out some of the

[beagleboard] Re: BBB 24-bit LCD using device tree

Ok, so I found out that fdd is the dma delay and also found the errata on 24-bit color to lcd pin mappings. That explains the colors being wrong. Still trying to find out why I can't change to 24-bit using the device tree. Any ideas? Brian On Monday, October 7, 2013 10:31:17 AM UTC-4,
