Problem moving from a 5i25+7I76 to a 7i76E.

In addition to 5i25+7I76 to a 7i76E I am also moving from  a J1800 MB to a ODroid H2+.
24V to TB1 pins 3 & 7 and TB3 pins 21 & 22 .  Each pair Positive, Negative respectively.
I can Ping the IP 10.10.10.10.
I have 3 LEDS that are on. one green CR5, and  two yellow CR8, CR13. 

Problem: When I run  "halcmd show all hm2" it shows no pins at all, just what is shown at the bottom of this post.

When moving from the 7i76 to the 7i76E just pulled the terminal strips off and moved them to the new board. 

I believe I have the jumpers set correctly.

Is linuxCNC running?
 If not, halcmd will show no hal pins,parameters etc

Yes,  I had tried it both ways.  I just tried it again a few times and I did see the pins show up once, but I am getting real-time excursions.  After that happens, no pins.   I had run the latency test on this PC with the 7i76 connected while it was on the bench and I got acceptable times.  Now that it is in the machine I also have a 7i83 connected.  Looks like I need to focus on the real-time excursions.

Thanks

This is where I am at. When I try to start LCNC from the command line it just exits. Any ideas

I tried this:
john@X3CNC:~$ mesaflash --device 7i76e --readhmid
No 7I76E board found
john@X3CNC:~$

I found this in the report file:

Debug file information:

In the loadrt lines you still have hm2_pci, it should be hm2_eth

Thanks Tommy, 
I knew it was going to be something like that.  I also changed all of the references to 5i25 to 7i76e

I kept running into problems that didn't seem to be coming from my hall or ini file so I decided to start over from scratch. I tried each of the various installation instructions and they all seem to end at the same place. On of the issues is the "error finishing read". On one attempt I installed the RTL8125 driver and updated the kernal to 6.3. The machine was and still is unusable. The currenct state was arrived at by installing debian and following the "Installing Linuxcnc on Debian Bookwork instructions. Starting Linuxcnc takes a very long time. It displays a message "Hard limits are reset to active!" Operator error: File not open. When it finally come up most buttons are unresponsive. I started from a terminal and below are the entries of interest. The PC is a ODroid H2+.
Am I doing something wrong here?

The hardware issues (non-QT related) are real time problems with the Ethernet interface

1. What servo thread period are you running?

2. What is the result of:

ping -c 4 10.10.10.10
and then
sudo chrt 99 ping -i .001 -q 10.10.10.10
(hit control C to stop and prints stats)

3. What is the result of

uname -a

 

Thanks Peter
