Communication error with 7i92+7i77 was created by Machinen
Hi,
I just bought new 7i92H+7i77 combo. Unfortunately I am having problems with setting it up (so far just on my table).
I flashed the 7i92 with 7i92_7i77x2D.bit using 2m CAT6E patch cable. I am powering both board with ATX power supply 5V by separate lines to both connectors, the field power is 12V from my lab power supply without earth reference. Cable between 7i92H and 7i77 is about 20cm long ribbon cable with idc26->db25 which I did perform continuity test on and also short circuit test. The installation I am using is from linuxcnc.org/docs/html/getting-started/g...th_preempt_rt_kernel , the kernel #1 SMP PREEMPT RT Debian 3.2.93-1, linuxcnc is LINUXCNC - 2.7.11.

When I try the
mesaflash --device 7i92 --sserial --verbose
I get the
SSLBP port 0:

So it is communicating. However when I try
halrun

Note: Using POSIX realtime
hm2: loading Mesa HostMot2 driver version 0.15
halcmd: loadrt hm2_eth board_ip="192.168.1.121"
I do get the following error:

Or something like it. IE sometimes the 7i92 communicates with 7i77 more, sometimes less.

I tried both idc26 connectors on the 7i92H.

Any help would be appreciated.

Thanks.

Edit: I forgot to mention that after this the 7i77 usually has the green led rapidly blinking and the red led shut off. To turn it back to no green light and constant red light I have to communicate to it by mesaflash or power cycle the 12V part.

Did you run a latency test on the host PC?

What is you host hardware?

The rapid green LED blinking likely means that the host has lost all communication with the 7I92 some time
during the sserial setup phase and its been left in the channel started phase but no commands have been issued

I actually did, the max jitter was on base thread under 50000ns and about half on servo thread.

Which Ethernet is the 7I92 connected to?

Do you have the 192.168.1.121 range overlapping with the other Ethernet?

Normally its suggested to use 10.10.10.10 for the 7I92 and 10.10.10.1 for the host
because this does not overlap common NAT ranges

It's the eth1 3c940 10/100/1000Base-T [Marvell] - the motherboard network card. The extra eth0 is for home network. For local network, I am using 192.168.88.0/24 so there should not be any overlap.

Last evening I even tried the 10.10.10.10 settings but with no effect - or actually there was one effect, for some reason the mesaflash --device 7i92 --sserial took forever on the 7i77 part.

I can try it again.

I would try the RT8139 for the 7I92
Marvel and Broadcom are known not working for real time

On mesaflash you need to supply the address if you use 10.10.10.10
(and the host needs to be configured properly as well)

OK, did change+restart and tried:
mesaflash --device 7i92 --addr 10.10.10.10 --sserial --verbose
SSLBP port 0:
  SSLBP Version: 1.43
  SSLBP Channels: 6
  SSLBP Baud Rate: 2500000
  interface type: 12
  interface width: 8
  SSLBP Channel Start: 112
  SSLBP Channel Stride: 50
  SSLBP Processor Type: d8
  SSLBP Clock: 100 MHz
And blinking cursor at the end.
Then after minute or so
  sserial device at channel 3: 7I77 GPIO
And blinking cursor again.

show?

For reliable eth connection when using 2 or more eth interfaces on the same computer, this has to be done for the port that the 7i92 or 7i76E is connected to :
Network manager chose "edit connections", double click on the wired connection , go to "ipv4" tab, change from automatic DHCP to manual, under it add the propper address ( 10.10.10.x or 192.168.1.x depending on the address set on the mesa board ), on that same page there is another button on the bottom right side ( am on the phone so i do not recall the label but most probably Advanced ), click on " use this connection for local....something. ok. Ok. Ok That is it.
