eDMA trouble - SPC560B

using the SPC560B-DIS board I'm having trouble with eDMA.

I've got a very basic function set up to write a succession of 32bit words from one array to another using the eDMA.

but it doesn't seem to ever get on to the second (or subsiquent) major loop iterations (as in CITER decriments the once but then not again)
If i manually reset the TCD.START, the next iteration happens (and if I keep doing this the iterations continue till CITER is zero and the done flag is activated)

However I assume that subsiquent 'loops' should be started by hardware.

Any help with this would be appreciated.
