Hi!

All my testing so far was performed using modules, though it shouldn't make
difference.

More stuff is needed, all those twl4030 regulator patches (already in
linux-next) + DTS initial-mode patch
(https://lkml.org/lkml/2016/4/17/78).

Aha, that explains a lot. Dealing with -next would be tricky, I guess;
can I just pull from your camera branch?

https://github.com/freemangordon/linux-n900/tree/camera

I guess yes, though I am not sure all the patches there are compatible with
userland different from maemo, so be careful. Also, the correct branch is
v4.6-rc4-n900-camera.

I tried v4.6-rc4-n900-camera, but got the same results: green mplayer
window, if I try to use front or back camera. Assuming
v4.6-rc4-n900-camera works for you, could I get your .config and list
of modules loaded during the test?


.config is 'make rx51_defconfig' from v4.6-rc4-n900-camera branch, with added:

CONFIG_VIDEO_BUS_SWITCH=m
CONFIG_VIDEO_SMIAREGS=m
CONFIG_VIDEO_ET8EK8=m

For some reason I have to do 'modprobe smiapp' after every reboot, before using cameras.

After taking a nap, a question came to my mind - what is that device you're using? As some early board versions use VAUX3 for cameras as well.

awk '{ printf "%s ",$1 }' /proc/modules results in:
