Hi PCW,Thanks for that. There's a problem with the sserial port; with the previous firmware (attached), the system as it's currently wired inc. the hal line:
loadrt hm2_eth board_ip="10.10.10.10" config="num_encoders=6 num_pwmgens=6 sserial_port_0=0000000" works and allows us to reference the 7i84 e.g.: hm2_7i97.0.7i84.0.3.output-00
Changing only the firmware to the one you posted above, lcnc fails to start with error:
twopass: Error in file ./morb01_IO_7i84.hal:
Pin 'hm2_7i97.0.7i84.0.3.output-00' does not exist
this is with all wiring identical. close checking of the readhmid output and manuals suggests that the sserial port settings should remain the same - is this expected?
Sorry, mismatch between advertised clock and real clock
so the baud rates were all off...
Denser configurations like this have a slower clock to meet timing
and this is the first time I have made on of these configs, and I had
not quite gotten al the ducks in a row...
Great, that's got the sserial and pktuart ports appearing and working, thank you for the quick response.
We have 3x identical modbus cards to communicate with. Using mb2hal it was possible to address each one but I can't see how to do that using mesa_modbus - is there a way to talk to different addresses over a single pktuart port? This may be a question for Andy Pugh...
It should be possible with hm2_modbus,
(as long as the devices sharing a link have the same baud rate)
mesa-modbus only supports one device (per host UART)
