Dear Kaspter,
Could You explain how did You disable lvds in u-boot?
I have the exatly same problem, with my olimex a20 som,
I dont have lvds clock, just constant high signal.
Thanks in advance

thank you George,
After some testing, 2 channel LVDS panel worked well if i disable lvds
output in uboot, hope this help others.

I don't have that system on the workbench right now but it was off of the
3.4 branch and pulled within the last few months. For reference here is the
display portion of my FEX:
[disp_init]
disp_init_enable = 1
disp_mode = 4
screen0_output_type = 1
screen0_output_mode = 4
I recently connected a 2 channel LVDS panel to Cubieboard2 (A20) and it
worked well with just the normal FEX file changes.

Hi all
LVDS two channels pannel can't works well, Can you explain how you write
directly in PLL registers and which values ?
many thanks.

LVDS works, but as I reported a month ago LVDS driver is buggy, if the LVDS
is one channel clock is OK, if the LVDS is two channels (like for Full HD
1980x1080p LCDs) the clock gets divided by the number of the channels which
is wrong and we fix this manually by writing directly in PLL
Hi,
I'm trying to run linux on my tablet. (K1001L1C)
I have probed PD7 pin to get know what is going on.
On android I get 52MHz LVDS signal.
On linux-sunxi I get high LVDS state (1,4V)
I tried to tweak fex file but I haven't got anywhere.
Regards.
