Rockpro64 with 7i76e

I have a Rockpro64 4gb and a mesa 7i76e. I currently have linux-stable-rt-4.19.31-rt18 plus linuxcnc installed.

The rockpro64 has a gigabit ethernet port. I assume (dangerous thing I know) that I should use the gigabit port to hook up the 7i76e. Does that sound correct?

The next problem is, if I want to run headless (ssh) should I buy the wifi module for the rockpro64 or would it work to buy a USB3 to ethernet adapter to hook to my network?

i use ETH mesa alot and the 3USD usb-> Eth workes perfect to get things from WWW
the Gigabit ETH is not a problem so you can move on
did you get a SIm mashine started so you know the Board is good on rt kernel

yopu shoudt follow the gnipsel.com setup to get the master 2.9 uspace on it

the wifi makes itr very flex to position the mashine like Plasmas to a save place and no real connect to the main shop needed

I just tried to start linuxcnc. I set jumper w3 up instead of down and the ini file is set for ip address 10.10.10.10. However, I got an error network unreachable.

Any suggestions appreciated.

Ping reports network unreachable.
When I tried the
halrun
loadrt hostmot2
loadrt hm2_eth board_ip="10.10.10.10" CONFIG="num_encoders=1 num_stepgens=5 sserial_port_0=20xxxxxx"

It reports unknown parameter 'CONFIG="num_encoders=1 num_stepgens=5 sserial_port_0=20xxxxxx"'
wait_pid failed /usr/bin/rtapi_app/hm2_eth
rtapi_app exited without becoming ready.

If ping doesn't work, it means your network is not setup to access 10.10.10.10
That's not really related to LinuxCNC but a basic network setup issue

Did you read the hm2_eth manual page? it has a bit about network setup
Also if your computer has a network setup GUI, set the host Ethernet port
to a fixed (static) IPV4 address of say 10.10.10.20

To find the ethernet adapter name
ip link show
or
ip a

sudo gedit /etc/network/interfaces

auto enp0s25 << change to match your interface name
iface enp0s25 inet static
address 192.168.1.100 << if you use the mesa card 192.168.1.121 ip
netmask 255.255.255.0
broadcast 192.168.1.255
# gateway 192.168.1.1
# dns-nameservers 8.8.8.8 8.8.4.4
