My graphic driver also is Intel GMA500.
I use ADBHOST to debug it.
I get log is below.
......
......
I/EGLDisplaySurface( 1695): using (fd=20)
I/EGLDisplaySurface( 1695): id = psbfb
I/EGLDisplaySurface( 1695): xres = 800 px
I/EGLDisplaySurface( 1695): yres = 480 px
I/EGLDisplaySurface( 1695): xres_virtual = 800 px
I/EGLDisplaySurface( 1695): yres_virtual = 480 px
I/EGLDisplaySurface( 1695): bpp = 16
I/EGLDisplaySurface( 1695): r = 11:5
I/EGLDisplaySurface( 1695): g = 5:6
I/EGLDisplaySurface( 1695): b = 0:5
I/EGLDisplaySurface( 1695): width = 127 mm (159.999998 dpi)
I/EGLDisplaySurface( 1695): height = 76 mm (160.421050 dpi)
I/EGLDisplaySurface( 1695): refresh rate = 63.06 Hz
It stops here, and I remove memset() function in
EGLDisplaySurface::mapFrameBuffer() of EGLDisplaySurface.cpp.
// at least for now, always clear the fb
memset(buffer, 0, finfo.smem_len); <---- remove it,
but why it stops without occur error.
Then it can continue running, but I found it stop eglCreateContext()
of egl.cpp.
It called by readyToRun() of BootAnimation.cpp.
So, I remove BootAnimation in SurfaceFlinger::readyToRun() of
SurfaceFlinger.cpp.
It still can not display any screen.
It stops
"I/ActivityManager( 1694): Start proc android.process.acore for
activity com.android.launcher/.Launcher: pid=1725 uid=10003 gids=
{3003}"
But using VESA VGA can display screen without boot animation.
How can I do it?
Thanks
