Hi, I'm struggling with LinuxCNC RPi distro, Remora, NVME V5 over the past week. I have flashed multiple versions of the firmware from Scott Alford's github page, but I can never get anything to work. here is the progress so far - I am able to ping the NVEM with no problem but when I do command tests like this one: 
halrun
loadrt threads name1=servo-thread
loadrt remora-eth-3.0
addf remora.read servo-thread
addf remora.write servo-thread
setp remora.enable 1
start
show pin remora.status
I get a false reading and from what if know so far, without a true result, I'll never get LinnuxCNC to communicate with the NVEM. I'm currenly have the 3.1.4 beta on the NVEM but with or without an uploaded config file, I get the false result: show pin remora.status: false. Is the issue to do with the eth driver or something .. as now I have almost given up  .. I have provide any readouts from commands from terminal? I know the NVEM is very picky at how it interprets code etc .. I was hoping this was going to be easy :)
Thanks is advance.

Have you tried to use the example configuration?

github.com/scottalford75/Remora-RT1052-c.../remora-rt1052-basic

There is some latching logic in the hal file:

net user-enable-out <= iocontrol.0.user-enable-out => remora.enable
net user-request-enable <= iocontrol.0.user-request-enable => remora.reset
net remora-status <= remora.status => iocontrol.0.emc-enable-in
