I tried it in Ctrl+Alt+F1 but I don't see anything because I only get 'TDMA: Failed to transmit sync frame!' at the master's side. I'm sure the cable is ok and connected because non-realtime pinging works. But I switched the master and slave. They both are again going to wait/search each other (in ctrl+alt+f1). When I run dmesg in f2 I get for the master (over and over again during the wait for slaves) : "r8169: rt18169_start_xmit: TX len = 60, skb -> len = 42, eth_proto=9021" For the slave I get the message: e1000: rteth0: e1000_watchdog: NIC link is up 1000 mbps Full duplex rteth0: no IPv6 routers present rteth0-mac: no IPv6 routers present. > >> [EMAIL PROTECTED]:/usr/local/rtnet/sbin# ./rtifconfig >> rteth0 Medium: Ethernet Hardware address: 00:10:C6:E1:B9:F2 >> IP address: 10.0.0.1 Broadcast address: 10.255.255.255 >> UP BROADCAST RUNNING MTU: 1500 >> >> >> Some info about the slave >> >> ## rtnet.conf >> # RT-NIC driver >> RT_DRIVER="rt_r8169" >> RT_DRIVER_OPTION="" >> # RT_DRIVER_OPTIONS="cards=1,0,0,0" >> IPADDR="10.0.0.2" >> NETMASK="" >> TDMA_MODE="slave" >> >> Dmesg returns: >> *** RTnet 0.9.9 - built on Jul 27 2007 13:13:28 *** >> >> RTnet: initialising real-time networking Initializing rt_r8169 >> driver<6>PCI: Found IRQ 5 for device 0000:00:0b.0 >> PCI: Sharing IRQ 5 with 0000:00:0a.2 >> PCI: Sharing IRQ 5 with 0000:00:0a.3 >> rt_r8169: PCI device 0000:00:0b.0: unknown chip version, assuming >> RTL-8169 r8169: -------------------------- >> r8169: dev->mtu = 1500 >> r8169: priv->curr_mtu_size = 1500 >> r8169: priv->tx_pkt_len = 1514 >> r8169: priv->rx_pkt_len = 1514 >> r8169: priv->hw_rx_pkt_len = 1522 >> r8169: -------------------------- >> RTnet: registered rteth0 >> rteth0: Identified chip type is 'RTL8169'. >> rteth0: rt_r8169 RTnet Gigabit Ethernet driver 2.2-04 at 0xd800, >> 00:15:f2:0f:68:68, IRQ 5 r8169: priv->mcfg=4, priv->pcfg=3 >> r8169: Set MAC Reg C+CR Offset 0x82h = 0x01h >> rteth0: Auto-negotiation Enabled. >> r8169: priv->linkstatus = 0x04 >> RTcfg: init real-time configuration distribution protocol >> RTmac: init realtime media access control >> RTmac/TDMA: init time division multiple access control mechanism >> r8169: Set MAC Reg C+CR Offset 0xE0: bit-3. >> [EMAIL PROTECTED]:~$ >> >> [EMAIL PROTECTED]:/usr/local/rtnet/sbin# ./rtifconfig >> rteth0 Medium: Ethernet Hardware address: 00:15:F2:0F:68:68 >> IP address: 10.0.0.2 Broadcast address: 10.255.255.255 >> UP BROADCAST RUNNING MTU: 1500 #### >> >> I hope someone can help me with it, I'm not very familiar (newb) with >> linux and real time networking. >> >> Thanks in advance, >> Jeroen Tnx ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
