Can lower version of the kernel use Syslink it? For example, Linux-2-6-33.

Hello Yezi,

What is the feedback from dmesg after the syslink.ko is loaded? For proper work it is mandatory to rebuild your kernel modules if the version of the kernel has been changed.

Best regards,
Kemal

After the syslink.ko is loaded,when I input the command "dmesg | less",the feedback from dmesg  is following:

Hello Yezi,

As you have written in the description:

"But it prints the following statement when runs the application --Ipc_attach: Ipc_procSyncStart failed!"

Which application is this?

Best regards,

Kemal

Hi Yezi,

Please restrain from opening duplicate threads in multiple forums - > http://e2e.ti.com/support/dsp/omap_applications_processors/f/42/t/406208 

Hi Yezi,
Always we recommend to use latest kernel version for SYSLINK since it depends on newer APIs from linux kernel.
Let me try this at my end and will update.
Have you tried DSPLINK examples on your board ?
