Backlight off - kernel 2.6.32.2

Hi,

I downloaded kernel 2.6.32.2 from friendlyarm.net downloads and compiled it
for mini2440 using buildroot.

Both uImage and rootfs.jffs2 are working, but my backlight is turned off.

I can see the pinguim image and login but the backlight is always off.

I'm using u-boot and I tried to change "mini2440" parameter, using like,
0tb, 1tb, 2tb and this does not make difference.

Same results for anything that i enter in "mini2440" parameter.

Some one know how turn on the backlight in this kernel?

This "mini2440" parameter is working in kernel 2.6.32.2?

Thanks.

Hi,

I solved the problem.

I was making the kernel 2.6.32.2 with default config instead of
t35_mini2440.

To compile with buildroot I put the t35_mini2440 inside
archs/arm/configs directory and select to use defconfig with the right
name. Name like "t35_defconfig"

Now, backlight is ok.

I tried the udev option and now everything is inside /dev/ backlight,
leds and etc.

Best Regards.
