Mark, thank your response very much! omapfb: Pixclock 72000 kHz hfreq 43.3 kHz vfreq 58.1 Hz About this line: I have checked, and all values are correct to our device.
omapfb: configured for panel omap3evm About this line: I connect my device to a LCD rather than DVI, so I use the lcd_omap3evm.o rather than lcd_omap3beagle.o, but I don't know if it is right. omapfb: Framebuffer initialized. Total vram 3686400 planes 1 About this line: The 3686400 means (1280 * 720) * 2 * 16(bits) / 8, I think it's right. Console: switching to colour frame buffer device 160x45 About this line: I don't know what is it doing, and I will check it right now. I appreciate your response very much!! Thank your help again!!!
