[directfb-users] problem about layers of directfb

[温]

 

hi everybody,

 

 

    I got a error when initializing directfb, it says:

 

root@sdk:~# df_dok --dfb:fbdev=/dev/fb0

../../src/df_dok.c <1573>:
        (#) DirectFBError [DirectFBCreate( &dfb )]: Not supported!
root@sdk:~#

     I  set some parameters in etc/directfbrc:

system=stgfbdev       

module-dir=/usr/lib/directfb-stsdk
mode=720x576
depth=16
pixelformat=RGB16
video-phys=0x83000000
video-length=691200
primary-layer=1
primary-only
init-layer=1
layer-size=720x576
layer-format=ARGB1555
layer-depth=16

 

 

   the first and second are set by SDK,  I don`t know why?   Anybody could help me?

Best regards,

  Wen ming
