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. Stanley.
