I started installing OMAP35xx_GFX_SDK_Beagle, which I got from TI, on my beagleboard following the INSTALL instructions. I booted the board and tried to start the drivers but it failed. Bellow is the output of the command: root@beagleboard:~# /etc/init.d/rc.pvr start pvrsrvkm: disagrees about version of symbol struct_module insmod: error inserting 'pvrsrvkm.ko': -1 Invalid module format mknod: missing operand after `0' Try `mknod --help' for more information. chmod: cannot access `/dev/pvrsrvkm': No such file or directory omaplfb: disagrees about version of symbol struct_module insmod: error inserting 'omaplfb.ko': -1 Invalid module format /* bellow is some information about the kernel version: root@beagleboard:~# uname -rsnm Linux beagleboard 2.6.28-omap1 armv7l Can someone suggest how to solve it, it will be grateful.
