error while inserting stgfb module

[Khaled B. A. <kha...@gm...>]

Hi every body!
I am working on a set top box reference design based on the chip st7109 and
I use STLinux 2.2.
I want to insert the framebuffer module (named stmfb_stb7100). For this I
did like the official web site of STLinux indicates for me (
http://www.stlinux.com/docs/release-note-2.0ear/framebuffer.php). First I
activates the kernel framebuffer options, rebuild it and then I built the
framebuffer module and install them.
All the necessary modules are inserted perfectly (cfbcopyarea.ko ,
cfbfillrect.ko, cfbimgblt.ko) but an error occurs during inserting the
framebuffer module (stmfb_stb7100) :


# insmod stmfb-stb7100.ko
insmod: error inserting 'stmfb-stb7100.ko': -1 No such device


same thing using modprobe :

# modprobe stmfb-stb7100.ko
FATAL: Module stmfb_stb7100.ko not found.
any suggestion to overcome this problem?
