Ok. Completely confused but I'll try to figure it out. Strange because this network approach works for my other lcnc-uspace set-ups.

I'll try to set-up the network like my dev pc is, which actually work with the w5500 directly connected into its ethernet port . Let's see how that goes.

I'll update on the Evil State!!

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

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):

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,

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.

Yes I did.

I've seen you made changes to your repo and so I've deleted everything locally and started fresh from scratch. Git re-cloned everything, recompiled the gateware, flashed to fpga, halcompile --install rio.c, then copied over the Linuxcnc config files. E v e r y t h i n g brand new!!

That way I ensured everything was fresh as you left it after your mods and tests yesterday. Even went and get the prod computer to test fresh onto.

Saturday's Evils I tell ya lol Trust it's a good day to panic!

Funniest thing is it works(ish) onto the PC I dev onto. That PC can't be used with Lcnc because of the crappy ethernet adapter... one of those affected realtek nic. At least I'm not getting this bad header error onto this PC. So weird... totally lost

no panik !!!

do you have recompile your hal-component ?

Tests carried. Tested onto my production Lcnc-uspace computer which host a high performance r8169 ethernet adapter. Same I use for my gigabit based lathe (LiteXcnc). Yet I'm unable to have Rio working on this one

Strangely enough, I get zero pkt losses and a fast ping response from the wizzy part on that computer. As if it likes it very much! Therefore fair to assume I'm connected solid.

So upsetting to see Rio working for others, but not for myself. I smell badluck arrggh

HELP, calling the Godz!!

If anyone would still look for pinouts, please see attached 

Hi 
I've got some weird issue with my configuration. 
When I home I should be on X0Y0. But I'm always 0.003 - 0.005 from this point on both axes. 

Same when I go to X50, it is stopping at 49.995. DTG shows 0. 
I've noticed in hal config that j0pos-cmd and j0pos-fb are different. 
It happens on all of the axes 
​​​Can someone advise anything?

You EtherCAT guys are doing a great job at making things more accessible but it will be some time before I'll send a newcomer looking for an easy entry down that path.

Not yet, there are things ti disable in BIOS, like hyperthreading, power saving, TPM, sleep states, turbo mode, speed step, etc.
And get the older Wheezy ISO as it uses the RTAI kernel and test with it, should do much better.
Also, repasting the CPU cooler will often make the PC usable.

My new project is a control panel. Always wanted to make one, but something kept getting in the way. Now I finally managed to realize it. Nothing special, the case itself is bent and welded from 2mm sheet metal, 12" touch screen monitor, industrial keyboard and all the buttons, computer also fits. All the buttons and MPG are connected via adruino. As usual, in many things had to figure out from scratch, the config turned out perhaps the most complex of those that I have ever done. But in the end, everything works as it should, thanks to this forum, I was able to find answers to all my questions here.
