Well, you have to cause EMC to use the correct 'device driver',
in this case it would be smdromod.o
This should be in the line
EMCMOT = smdromod.o
in the [EMCMOT] section of the .ini file.

Also, the device address has to be specified in some parameter to the
EMCMOT routine, it might be in STG_BASE_ADDRESS = xxxx

The SHMEM_BASE_ADDRESS = 0x1F000000 line needs
to properly specify the address of the shared memory region,
at least for some early versions of EMC/RTLinux.

You should check the diagnostics window to make sure the
'heartbeats' displays are counting up at a high rate. this demonstrates
that the RT section of EMC is in communication with the non-RT
section.

Those are the most obvious things I can think of.
