After speaking with an engineer @ ergpower I have the part needed to power the
frontlight on the Sharp LQ039Q2DS54 Display.
The part # is 8m122375
its an 8m Class DC to AC inverter
The cost per unit is $29 each, for a qty of less than 10.. there is a minimum
order amount of $100. And a lead time of 4 weeks..

Unless you obtain an AC inverter for the frontlight on the Assabet, enabling the
frontlight in software will do nothing.
After doing a bit of research (and calling intel) i was able to find a vendor
for the inverter..
Endicott Research (www.ergpower.com)
2601 Wayne Street
Endicott, New York 13760
607-754-9187
fax 607-754-9255
I was able to find out that they do have an inverter that supports the Sharp
LQ039Q2DS54, but every time i try to contact the engineer, he is not at his
desk!?!? I will try again today, and see if i can get more info.. pricing..
etc..

Subject: LCD backlight on Assabet BD problem
Greetings,
Now I am trying to turn on the LCD backlight on Assabet board, however,
I don't know how to achieve this.
In /video/sa1100fb.c, there is a function of
sa1100fb_enable_lcd_controller (), and it contains the following
routines.
if (machine_is_assabet()) {
#ifdef CONFIG_SA1100_ASSABET
BCR_set(BCR_LCD_ON);
#endif
} else if (machine_is_penny()) {
#ifdef CONFIG_SA1100_PENNY
FpgaLcdCS1 = 0x0FF; /* LCD Backlight to 100%
*/
FpgaPortI |= LCD_ON; /* Turn on LCD Backlight
*/
#endif
} else if (machine_is_tifon()) {
GPCR = GPIO_GPIO(24); /* cycle on/off-switch
*/
udelay(150);
GPSR = GPIO_GPIO(24); /* turn on display */
As you can see, LCD backlight seems to work in the case of PENNY, but
Assabet does not. (Am I right?) What can I do for turning on LCD
backlight? Any ideas?
