dsplinkk.ko compatibility

Added by Krishna Vallabhaneni over 11 years ago

The MityDSP board has installed Linux kernel v 3.2.0. This was required for compatibilty with g_ether.ko driver for ethernet over usb gadget.

However the dsplinkk.ko driver from MDK_2012-08-10/sw/3rdparty/dsplink_linux_1_65_00_03/dsplink/gpp/export/BIN/Linux/OMAPL138/DEBUG/dsplinkk.ko
is no longer compatible!

insmod dsplinkk.ko
dsplinkk: disagrees about version of symbol module_layout
insmod: error inserting 'dsplinkk.ko': -1 Invalid module format

Need a compatible version of dsplinkk.ko asap

How do I generate a dsplinkk.ko compatible with kernel version 3.2.0 ?
The TI site is for kernel version 2.6.30.

Thanks

There should be a dsplinkk.ko file in the /lib/modules/3.2.0/ directory in the reference filesystems. See http://support.criticallink.com/redmine/boards/10/topics/2068?r=2073#message-2073

There is a blurb about rebuilding the module for a modified kernel if you need that.

Hello All,
I successfully rebuilt the kernel to the version 3.2.0, then I tried to install the kernel object dsplinkk.ko .
I used the one given with the MDK of August 2012, in the directory suggested by Mike /lib/modules/3.2.0/
after giving the command:
"insmod dsplinkk.ko"
Prints out an error as:
"
dsplinkk: disagrees about version of symbol set_user_nice
dsplinkk: Unknown symbol set_user_nice (err -22)
dsplinkk: disagrees about version of symbol wake_up_process
dsplinkk: Unknown symbol wake_up_process (err -22)
insmod: error inserting 'dsplinkk.ko': -1 Invalid parameters
"
What do I need to do?

Thank you very much!

Michele

If you added or removed features from the kernel, you may need to rebuild the dsplink drivers.

To do that:

  1. source the toolchain setup script like you did to build the kernel.
  2. cd to ${MDK}/sw/3rdparty/dsplink_linux_1_65_00_03/dsplink
  3. edit the setenv-bash and change the ARM_BASE_BUILDOS to point to your kernel build tree
  4. run the build_arm.bash script
    .../dsplink# . ./setenv-bash
    .../dsplink# . ./build_arm.bash
    

If it works, there should be a gpp/export/BIN/Linux/OMAPL138/dsplinkk.ko file (newly built, check the timestamps)

I updated my instructions to clarify the commands on the last post...
