Frame Buffer issue in Linux DM8168

 Hi,

I am using DM8168 processor with my customized daughter board. The EZSDK version is 5_05_02_00 and Linux version linux-2.6.37-psp04.04.00.01

Here while I am dumping image to LCD, the image will appear and disappears immediately.

I am using the following procedures given below.

insmod syslink.ko

  ./slaveloader startup VPSS-M3 ti816x_hdvpss.xem3

insmod vpss.ko address=0xB2C00000 debug=1
insmod ti81xxfb.ko vram=0:16M,1:16M,2:16M debug=1

echo 0 > /sys/devices/platform/vpss/display1/enabled
echo 800x480@60 > /sys/devices/platform/vpss/display1/mode
echo 1 > /sys/devices/platform/vpss/display1/enabled
echo 1:dvo2 > /sys/devices/platform/vpss/graphics0/nodes

cat My_image.raw > /dev/fb0

After I executed the above commands, the image appears and disappears in LCD (I mean its going to BG and appearing in the FG).

What might be the reason for this issue?.

If I execute the below commands as like u mentioned, I can able to see the image in the FG of my display.

cp My_image.raw /dev/fb0
cat /dev/fb0

Why its behaving like this?. Normally its supposed to visible in FG instead of BG.
Whether it is the issue or the driver itself designed like this.?. If it is the issue, could you please help me to solve this?

And one more information, if I run the matrix-GUI in the LCD, it is appearing in the FG.

Thanks in advance.
Regards,
Salih
