run loadmodules.sh FAIL!

Hi Changsheng,

root@arago:~/omapl138/usr/share/ti/c6run-apps# ./loadmodules.sh

cmemk: disagrees about version of symbol module_layout

dsplinkk: disagrees about version of symbol module_layout

This issue is due to be mismatching between kernel versions.

You may compile DSP & CMEM kernel driver as a module with some linux version and now you are booting with different kernel version and trying to loading those modules drivers in modified kernel.

I think that you are using pre-built CMEMK & DSP module drivers which comes with TI SDK.

To avoid this , You have to recompile the DSP & CMEMK drivers as module.

Please refer the following TI wiki links for rebuilding those module drivers with your latest modified kernel.

Hi Titusrathinaraj :

    Thanks very much!

    I solved model version not match!  But another problem disapear:

root@seed:~/omapl138/usr/share/ti/c6run-apps# ./loadmodules.sh CMEMK module: built on Mar 10 2014 at 16:57:26

  In my board, there is 256M DDR2 memory.

  What should I do to resolve it?

  Thanks very much!

Hi,

Refer the following link to pass the args while inserting cmem module driver,

http://processors.wiki.ti.com/index.php/CMEM_Overview#Test_Setup_and_Validation_Process

I think that you are accessing invalid address on DDR memory.

Pass different phy start and end & pools argument value while inserting cmem module driver through "insmod" and not through loadmodules.h, Once it is tested then use those values in loadmodules.h file.
