I have been trying for a long time to run any of the sample programs provided with the syslink package on a Spectrum Digital 816X EVM.
I can build the samples, but when I attempt to run them I get errors like the following:

Following suggestions elsewhere I have tried unsuccessfully to update syslink.ko as described in the installation guide.
The command: rmmod syslink results in the error:
ERROR: Module syslink is in use by vpss.
I have searched in vain for a way to stop vpss. The possibility of rmmod failing is not mentioned in the syslink install guide.
I cannot see any process that suggests it is related to vpss. Here is the list:

How do I update syslink.ko?
