OMAP35xx EVM video not working (display in red colors)

Hi

I'm interested to found a kernel higher or equal than 2.6.25 that
support the OMAP35xx EVM board.

The SDK that came with the board (OMAP35x_SDK_0.9.5) is 2.6.22.18.

I try with
2.6.26-omap2
2.6.27-omap1
2.6.28-rc8
and all gives my a display with red & black colors when for exemple I
run /usr/tests/demo from SDK.

Is this a known problem with FBDEV and V4L2 Video display driver with
OMAP35xx EVM?

Thx for helping me to understand the problem.

Regards

ps: If you need me to to some test I'm ready!

Koen,

Questions:
why uImage...omap3evm.bin ? I try to chmod +x then ./uImage.bin
result: cannot execute binary file

I imagine that it is a normal uImage that end with .bin?

Since I have seen a lot of your post related with Open Embedded and
Angstrom is it possible that uImage have been generated with
http://www.angstrom-distribution.org/

thx

Koen,

I just try your kernel image and colors for the display are just
perfect!

But went I start /usr/tests/demo the keypad is not reacting as
expected, pictures are not changing when I pressed keys.

[root@OMAP3EVM /]# ls /dev/input/
event0 event1 event2
This mean that
CONFIG_INPUT_EVDEV=y

So do you now what is missing?

Is it possible to know where can I get the source code of this.

Regards

kap

[root@OMAP3EVM /]# ls /dev/input/
event0 event1 event2

It was built with OpenEmbedded, so you'll have to get the list of patches from there.
