Check the framebuffer resolution in: # adb shell cat /sys/class/graphics/fb0/virtual_size

Here you can check if the display is set to the right resolution/timing: # adb shell cat /sys/devices/omapdss/display0/timings Zoli On Thu, Feb 9, 2012 at 1:03 PM, carchangel <[email protected]> wrote: > hello everyone > > I am using the Blaze board to run Android 4.0 system which have the > Linux kernel 3.0.8. > > the u-boot ,x-loader and kernel is downloaded and built by the > [L27.IS.2.P2 OMAP4 Icecream Sandwich Release Notes] which is recorded > in > http://omappedia.org/wiki/L27.IS.2.P2_OMAP4_Icecream_Sandwich_Release_Notes > . > > Now the kernel can start normally ,but the LCD scree only flashed once > at kernel starting. after starting ,the kernel always black.the strange > log is > > 6.706115] cannot apply mgr(lcd) on inactive device > [ 6.711791] omapfb omapfb: failed to apply dispc config > [ 6.720703] cannot apply mgr(tv) on inactive device > [ 6.726257] omapfb omapfb: failed to apply dispc config > [ 6.735015] cannot apply mgr(lcd2) on inactive device > [ 6.740692] omapfb omapfb: failed to apply dispc config > anybody can give me some advise? > thanks > zhong yifeng > > -- > unsubscribe: [email protected] > website: http://groups.google.com/group/android-kernel -- unsubscribe: [email protected] website: http://groups.google.com/group/android-kernel
