Hello, I have Intel Gigabit-Cards and RTnet 0.9.6, Rtai 3.3 with 2.6.15.7 kernel. The RTnet server starts with the following error:TDMA: failed to transferred sync frame For what reason?
Likely because the TDMA subsystem ran out of buffers while the rt_e1000 consumes them but doesn't transmit yet.
The client can connect with the server, but rtping and everything else isn't possible. What can I do?
There has been reports that it takes about 2 s after "rtifconfig up" to get any packet out. The TDMA master starts its cycles earlier and may run out of memory therefore. Try putting an explicit "sleep 3" (to play safe) in the rtnet start script and check again.
Unfortunately, I still have no hardware access to test this issue, find the reason and resolve it or install a workaround.
HI! I have the same problem, I have RTnet 0.9.8, Rtai Magma with x86_64 kernel 2.6.19.7 I start the server then when it say "Waiting for all slaves" a start the client, than the server error: "TDMA: Failed to transmit sync frame!" I put the sleep 3 in the start script but I have no success, what place I have to put "sleep 3"? after "rtifconfig up" ? What can I do?
