The result is the same after power cycling. What part of the hal file is the driver command line? I assume it must be in the first part where all the realtime HAL components are loaded:

setp hm2_7i76e.0.dpll.01.timer-us -50
setp hm2_7i76e.0.stepgen.timer-number 1

I did some searching around and it seems I must modify this line (and possibly others), but I could only find documentation for what to add when you are using multiple FPGA cards, not for daughtercards.

loadrt hm2_eth board_ip="10.10.10.10" config=" num_encoders=1 num_pwmgens=0 num_stepgens=5 sserial_port_0=00xxxx"

Thanks for your help,

Ah ok, that makes total sense now that I'm seeing it. I did actually look at man hostmot2 but didn't quite understand how it worked. Everything is hooked up and working as it should now, thank you very much.
