Hi all,
 
I'm trying to enable the GPU on my gumstix overo fire.
 
I added the omap3-sgx-modules and libgles-omap3 modules to my image, did a bitbake, loaded the image, and here's what I get on boot:
 
Starting PVR
omaplfb: OMAPLFB_Init: OMAPLFBInit failed
FATAL: Error inserting omaplfb
(/lib/modules/2.6.32/kernel/drivers/gpu/pvr/omaplfb.ko): No such device
 
 
When I try to insmod /lib/modules/2.6.32/kernel/drivers/gpu/pvr/omaplfb.ko
manually I get the same error.

P.S. Here is my boot output in case it is of any use:
