Hi, all:
Thanks a lot for your previous helps. I have been trying to set up an
RTAI/RTnet machine for quite a while and Have not still successfully
communicated with the network. (simple RTping another
linux box never succeed).
I attached the routing and installed module information below for your kind
help.
I would like to do the following simple things, if this is not feasible, could
please experienced people in the group correct me, in order not to waste my
time if that is not working at all.
1. A regual linux machine <--> RTAI/RTNET Linux box.
I will use regular UDP on linux side and on the RTAI/RTNet side, I would use
to use RT Task, RT UDP/IP over the real time ethernet driver. Unless the
UDP/IP
protocol is changed, this should work.
This basically means I want to use UDP/IP services inside RTAI/RTNET real time
task to communicate with other non RTAI/RTNET machine.
It is not necessary to have RTMAC, TDMA in above picture. Just need RT UDP/IP
interface and the RT ethernet driver.
Does the above scenario work? If not, please do help, so I will give up this
approach at the first step.
I want to do above, just want to prove my changes in the Kernel scheduler
handling, and I do not need a real time network.
1>>> Please help me to clarify if above frame works. ???
2>>> If above works, you can help me to see the attached information and see
why my rtping failed ???
3>>> It would be greatly appreciated if somebody can just tell me the
procedure
and what I should do to set up above framework and environment, and I can
verify that if I miss anything or anything wrong in my steps.
If anybody experience above, do they have a procedure or step list for
reference, so I can just follow and it would work. ???
Really Appreciated a lot!!
I am runnong linux kernel 2.4.25 with RTAI v3.0r4 with rtai_hal. rtnet has the
revision of 0.7.1
