[RTnet-users] Communication between realtime and non-realtime stations

[Mnatsakanyan, M. <m.m...@tu...>]

Hi,

I need to setup communication between a realtime and a non-realtime machines.

I am not expert in this field so I tried to read all relevant documents and posts carefully.
There are several posts related to this problem but they did not help me to solve the problem.

Can someone check what I am doing wrong or just list the steps which I need to follow?


----------Real time setup-----------
Linux kernel version 3.8.13
xenomai version 2.6.3
RTNet version 0.9.13
NIC driver: r8169

Installation of RTNet and rt version of the driver were successful and I am able to bring up interfaces.

I am trying to bring up communication with non-rt windows machine.

Here is what I did:

let's say ipaddr, macaddr, gwaddr are IP, MAC and Gateway addresses of my rt machine
and ipaddr_w, macaddr_w for windows machine.  

I did not use rtnet script as inserts also TDMA module, which I cannot use in this case.

rmmod r8169
mknod /dev/rtnet c 10 240
insmod rtnet.ko
insmod rtipv4.ko
insmod rt_r8169.ko
insmod rtmac.ko
insmod nomac.ko
insmod rtudp.ko
insmod rtpacket.ko
insmod rt_loopback.ko
insmod rtcap.ko

rtifconfig rtlo up 127.0.0.1
rtifconfig rteth1 up ipaddr netmask 255.255.255.0 
nomaccfg rteth1 attach
rtroute add ipaddr netmask 255.255.255.0 gw gwaddr
rtroute add gwaddr macaddr dev rteth1
rtroute add ipaddr_w macaddr_w dev rteth1

I can confirm that rteth1 and rtlo are up.
When I try to ping from both machines, I get request timed out (or 100% packet loss) .  
Am I missing something?

Best regards,
Mari
