Rockpro64 with 7i76e

Andy,
Thanks.
I crashed my uSD and I am now trying to rebuild a new version on Buster. I really like the Desktop version. I had a version of linux-5.0 running on stretch but they have changed some things. I can boot it via ssh from my mac but the rt version won't display on my HDMI monitor.

I tried again to get rt_preempt running on Buster. I built the kernel linux-5.2.10-rt5-rockchip64 it will run but has a problem with ssh in from my mac. So I downloaded a later patch linux-5.2.14-rt7 and built linux-5.2.14-rt7-rockchip64 and it appears to run with out error.

I built linuxcnc (userspace) using John Thornton's instruction for the raspberry pi4b. I was able to start linuxcnc via ssh from my mac and got the config selector window. I didn't have my 7i76e plugged in because I haven't bought a USB3 to ethernet converter. Now that I have rt_preempt and linuxcnc both apparently running I will have to do that.

I tried again to build linuxcnc on my rockpro64 but I am getting some errors on
"sudo dpkg -i linuxcnc-uspace_2.8.0~pre1_arm64.deb"

(Reading database ... 185225 files and directories currently installed.)

The instructions say:

Now edit debian/control.bottom.in and remove the following lines
python-gtksourceview2
python-vte,,

but the lines are not in debian/configure so I can't delete them.

So does anybody have any suggestions???

Well if I could just read. I missed the "edit debian/control.bottom.in".

Well, I finally got linuxcnc all compiled and installed.
I just ordered the usb3 to ethernet adapter. I should have it by the end of the week. I made sure to order one that people say works with linux. It is made by a company called "Plugable".

I got my USB3 to ethernet adapter. I am using it to run ssh -Y and the rockpro64's onboard gigabit ethernet for the ethcat.
I thought I had set up userspace but I notice in the error messages "Using posix realtime". Is this correct? Any help on what I have done wrong?

Below is my /etc/network/interfaces file and the error messages from linuxcnc and the /home/acondit/linuxcnc_print.txt.

I tried to follow these directions -- ====Network setup for mesa cards: ======:

- left click on the network manager on the bottom right side or upper right side where the clock and volume is.
- choose "edit connections"
- double click on the network you want to edit ( usually "wired connection X")
- click on the "IPv4 settings" tab
- choose "manual" on the "method" drop down menu
- click on "add"
- write the address as 10.10.10.11
- never use 10.10.10.1 or 10.10.10.10 for the above
- netmask should be left as is ( usualy 8 )
- gateway should always be 10.10.10.1
- additional DNS servers should be 10.10.10.1

when I get to :
