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!!!
Best Regards

Hello, everybody.
I installed the android and linux kernel which Beagle Board released
in my OMAP3530 device, I have modified the
omap3_android_beagle_defconfig to enter the kernel on my device,
The clock is correct, and so do the xres and yres.
omapfb: Pixclock 72000 kHz hfreq 43.3 kHz vfreq 58.1 Hz
I/EGLDisplaySurface( 704): using (fd=21)
I/EGLDisplaySurface( 704): id = omapfb
I/EGLDisplaySurface( 704): xres = 1280 px
I/EGLDisplaySurface( 704): yres = 720 px
I/EGLDisplaySurface( 704): xres_virtual = 1280 px
I/EGLDisplaySurface( 704): yres_virtual = 1440 px
I/EGLDisplaySurface( 704): bpp = 16
I/EGLDisplaySurface( 704): r= 11:5
I/EGLDisplaySurface( 704): g= 5:6
I/EGLDisplaySurface( 704): b= 0:5
I/EGLDisplaySurface( 704): width= 51 mm (637.490173 dpi)
I/EGLDisplaySurface( 704): height = 38 mm (481.263153 dpi)
I/EGLDisplaySurface( 704): refresh rate = 60.03 Hz
It is scuessful to enter the kernel. However, the display didn't show
anything. The following link is my debug message:
http://pastebin.com/m6e0e3db9
I use oscilloscope to measure the signal, the clock is 72000 khz, but
there is no any data sent!!!
Why the CPU doesn't send any vedio data??? Is it possible that the
android system error? Such as it didn't enter the UI??
Please notify me if you have any advise, and I would appreciate you
very much !!!
Best Regards
