E680 navigation LED

[mickeyl]

Can anyone point me to where/how the E680(i) blue navigation LED is turned on or off? I just finished the first bits of a Linux LED class driver for the E680(i) and now I want to add the navigation pad LED, but I can't find in the 2.4 source where this is accessed.

mickeyl, I could'nt download gpiotool from openezx so I cannot confirm this, however if you can do something about it, I'd tell you that application processor's GPIO46 connects to RED and GPIO47 connects to GREEN/BLUE LED somewhere in the unit.

dunno if it's the one under the logo, or the one under the navigation pad.

would be cool if there is a simple way to turn it off and on, i think that would make for a much better way to show a missed call, message, could turn it off and on to make it blink, or just turn it on period.

Search for schematics on this site, there I hope you'll locate where navi stuff is wired to.

Thanks for your answers. I have since found the kernel 2.4 code to tweak it in keypad.c (I was blind...). The blue navigation LED is wired to pxa GPIO_TC_MM_EN which is also used for AP->BP communication.

Since the openezx kernel is still missing some of the initialization, that is probably why the 2.4 code doesn't work yet in 2.6.

on side note,
what executable code is used for the led command in the lin script used in funlights?
or is led a native command in the script?

led is a native app. if u r interested in led's code, its here somewhere. i saw led.c myself. need to do a search.

I send you many thanks
I had it in my archive and didn't realize it

anyone willing to recompile the following for me?
I commented out some error check and some printf() statements
so the new compiled code will be a few bytes shorter
