Re: irda on the ipaq shell WORKING

Hi,

ok, i did get it to work with my compiled zImage, its just that the
screen and backlight are turned off during boot, and i thought it died...

If i didnt miss something, nobody has volunteered to do some testing on
h2200_lcd.c yet,
i would like to try to take axim5_lcd.c and basically copy it into
h2200_lcd.c, then try, if i can turn the lcd/backlight back on using
/sys/class/lcd/mq11xx_fb0/xxx.

I hope to get around to do that maybe on the weekend...

Greetings,

Patty
