Yes confirmed I have 24V to field and a 5V 2A supply for the 7i92 with jumpers set to pass to the 7i76, both power lights on the 7i76 as well. Going through the 7i92/7i76 config from pncconf I commented out all of the lines that prevented linuxcnc from starting up. Essentially it was all of the 7i76 io pins, can be seen in the attached HAL file. When I had it running I ran HAL show pins and attached the output as well. The only io pin that allowed a startup was hm2_7i92.0.gpio.000.in which I think is a 7i92 pin directly and not addressing the 7i76? As well, the stepgen pins also didn't cause issues but when jogging around with an led attached to the direction pin it is flashing both ways, not on one way and off the other as I would expect.
One error I was not expecting is "unexpected realtime delay on task 0" and "hm2/hm2_7i92.0: error finishing read! iter=6" I have servo_period set to 20,000 with my max jitter over 4 hours measured as 16246. I had to increase the servo period to 500,000 to make these errors on startup go away.
I feel its time to put the 7i76 aside and get the 7i85 working with analogue outputs so I can get some machining work done. Is there an example someone has to address io and analogue pins on a serial connected device to the 7i85? I have a 7i83 and 7i84 connected for io and analogue out.
Cheers,
