how to rmmod syslink - it will cause kernel error

Dear Experts,

I am using DVRRDK3.5 ~

I execute below commands to load dsp/m3 firmware.

cd /opt/dvr_rdk/ti814x/
./init.sh
./load.sh

This will install modules: osa_kermod and syslink ~

I can rmmod osa_kermod. But can't rmmod syslink ~

kernel will report "Unable to handle kernel paging request at virtual address...."

Can anyone tell me how to rmmod syslink?

Or how to reset/reboot dsp/m3 ?

I want to reset/reboot dsp/m3 because I want to avoid encoding fail.

    You cannot rmmod syslink until you execute unload.sh . What is it that you want to do. You description of "I want to avoid encoding fail" is not clear.Do you want to recover from dsp/m3 crash by reset/restart slave cores ?

    Dear Badri Narayanan,

    After execute unload.sh. I can rmmod syslink module.

    Yes, I want to recover from dsp/m3 crash by reset/restart salve cores.

    And how to .stop/reset dsp/m3, because they are hang-up sometimes.

    Do you know how to achieve that?

    Is unload.sh a command to achieve that?

    I also want to stop dsp/m3 if I don't need to use them anymore.

    thx ~
