LinuxCNC-RIO - RealtimeIO for LinuxCNC based on FPGA (ICE40 / ECP5)

do you run halcompile on the linuxcnc host ?
or at least you have to copy the rio.so (from halcompile) file to /usr/lib/linuxcnc/modules/ on the lcnc host

yes of course, or else it wouln'd have connected to the fpga. From the host computer: $ sudo halcompile --install rio.c 

Can I bother you more and ask to see how you configure your network interface on your lcnc linux? Below is what mine look like. 

your log say's: wrong header: 116, 105, 114, 119, 0,...

this is the tx header, it looks like you get the data back you have send (UDP-loop test or so).

the right rx header is: 97, 116, 97, 100,

ahhh, ok, your lcnc host have the ip of the rio-interface, that explain also the udp-loop
set it to 192.168.10.1 or so

for subnet you can use 255.255.255.0 (bcast is than 192.168.10.255), but that should also work

Ok that's great, at least we know why it doesn't work on this pc. If I set the interface IP to 192.168.10.1 then I can't ping the fpga anymore. I'm confused. For the record the FPGA/w5500 is connected directly into the Wired connection 2. 

Just to double confirm, you mean like this? (that doesn't work btw):  

i never used nmcli, so don' know, but i would use '192.168.10.1/24'
