I have an LCD screen with an LVDS interface that I need to wire up to
the Beagle Board though I'm not planning on integrating the EDID stuff
at the moment. From various threads in this list, it seems that I have
to modify the kernel to make the screen work but no pointers to what
exactly needs to be done.
btw, I'm running the latest Angstrom demo image on a Rev. C2 board.
I entered the bootargs in the u-boot prompt following the brief
tutorial on how to get Angstrom running:
Do I actually have to modify any registers to change the clock
frequency or is just interfacing the LCD panel and setting the
bootargs (without any changes to the kernel) enough to get my display
working?
Andreas,
From what I've seen, you need to look at the signal names on the LCD
pad layout because they are out of order to get the layout to work.
That means custom wiring instead of just dropping in a ribbon cabled
connector. The other thing is that the Beagleboard LCD signals are
1.8V or something like that and will need level shifting to match what
your display signal levels are. After all that, then it's software
time and hopefully someone can point you to what's needed.
ok, I saw the "I need to wire up.." part of your post and thought I
could help with that part. Glad you've got that licked and hope you'll
post what you did regarding the hardware connectivity and level
shifting. I do plan on addressing this one of these days.
I'll keep quiet now and watch to see if any of the kernel people
answer the questions on enabling the software interface side.
