omapfb problem on 3430sdp

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hardware: 
	Mainboard: 750-2094-001(C)
	Display board: 750-2081-101(B)

Software: 
	the lastest kernel from linux-omap-2.6 and from omapzoom.org.

The linux bootup logo is green, and LCD is dark. It looks like backlight
disabled. 

I commented the following two sentences in lcd_2430.c, there is still
the same thing. It seems these two sentences doesn't work.

 96         omap_set_gpio_dataout(enable_gpio, 1);
 97         omap_set_gpio_dataout(backlight_gpio, 1);

Both the the latest kernels from omapzoom.org and linux-omap-2.6 have
this problem.  However, the old version in linux-omap-2.6, 2.6.21,
doesn't have this problem.
