Framebuffer not detecting image

The command,

fb-test -f 0

generates and displays a test pattern on the screen.

But the command,

cp /home/root/test.jpg /dev/fb0

copies the test image into /dev/fb0 but fails to display anything on the screen.

How to resolve this issue?

Hi Abhijeet

one can redirect image directly to the framebuffer device as follows:
cat image > /dev/fb0

FSL-UT-FB-003.txt\doc\mxc_fb_test\test - imx-test - i.MX Driver Test Application Software 

Best regards
