Hi all,
Thanks for all your help - I now have all my old functionality back on the 7i76e.
Missing firmware - yes solved - I had indventently removed both instances of the sserial module (which I hadn't realised were needed for the field IO). Putting one back fixed the problem - and still left me with the required pins for a "TTL" serial.
Here is the snippet if anyone is interested.
I had a few other odd problems which I'm not sure how they arose - in particular I got SCFIFO errors but only when running the z stepper. But I had the pktuart hal update function on a much slower thread (100ms) than the main servo thread (to try and minimise serial through put). Anyway - moving that function onto the main servo thread seemed to stop that error.
Anayway - all good - on to the next step ....
