    Hi Ravi,

    ./loadmodules.sh
    cmemk: disagrees about version of symbol struct_module
    dsplinkk: no version for "struct_module" found: kernel tainted.
    insmod: error inserting 'cmemk.ko': -1 Invalid module format
    DSPLINK Module (1.61.03) created on Date: Apr 16 2009 Time: 18:37:45

    CMEM Error: init: Failed to open /dev/cmem: 'No such file or directory'

    The log seems to be, the "cmem" driver module compiled with some kernel version (say 2.6.37) and tried to insert the module in different kernel version (say 3.2)

    We need to build the cmem module with current booted kernel version.

    What is your processor ?

    What is your kernel version ?
