Backlight control on WinCE 6.0

Hi,

I have been experimenting with LCD 7" backlight in Windows CE 6.0. I have
changed PWM driver in order to manipulate GPB1 too, and when I was capable
to control it, I change resistor in LCD PCB... everything works great, but
PWM just appears when Windows starts and launch my application.

How can I force uC to start PWM signals as soon as possible? I think my app
should transform in a driver loaded every time in a very early stage of
winCE, but I'm not sure how can I do... by now, I just have an app
configured to launch with Windows start, but I cannot see logo while OS
loads, nboot bar, etc.

I'll be waiting any answer, thank you!
Leo

Hmmm, you need to modify the nboot bootloader to either enable the PWM or
to atleast set the backlight to full on...

Thanks,
Errol
