I'm running into another problem porting the ns9xxx-eth.c network driver to RTnet. Slave mode works well when connecting to a known working PC with RTnet, and rtping works fine after the connection is established. But device cannot establish a connection in master mode, neither while broadcasting for the PC nor while using another identical device (which obviously is known to work in slave mode).
I've verified that the RTcfg Stage 1 Config packets are identical (except for IP addresses) between the working setup (in slave mode) and the non-working condition (in master mode). The problem seems to be with the TDMA Sync packets. There are a number of fields which are simply not populated. The "Cycle Number" is incrementing and "Scheduled Transmission Time" appears to be a somewhat reasonable value. Why would the other values not be populated? (see data capture below) Thanks, - James ___________________ Device as Slave - packet captures: 0000 ff ff ff ff ff ff 00 30 ab 02 87 df 90 21 00 01 .......0 .....!.. 0010 02 00 02 01 00 00 00 04 9a 1a 11 7e 0b 2d 7a d5 ........ ...~.-z. 0020 b4 24 11 7e 0b 2d 7a d5 b0 ec 20 73 6c 6f 74 20 .$.~.-z. .. slot 0030 30 20 32 30 30 3b 69 66 63 6f 6e 66 0 200;if conf 0000 ff ff ff ff ff ff 00 30 ab 02 87 df 90 22 00 01 .......0 .....".. 0010 0a 65 01 7e 0a 65 01 7f 04 00 42 24 54 44 4d 41 .e.~.e.. ..B$TDMA 0020 43 46 47 20 72 74 65 74 68 30 20 73 6c 6f 74 20 CFG rtet h0 slot 0030 30 20 32 30 30 3b 69 66 63 6f 6e 66 69 67 20 76 0 200;if config v 0040 6e 69 63 30 20 75 70 20 24 49 50 41 44 44 52 20 nic0 up $IPADDR 0050 24 4e 45 54 4d 41 53 4b 5f 4f 50 54 0a $NETMASK _OPT. ___________________ Device as Master - packet captures: 0000 ff ff ff ff ff ff 00 04 f3 ff ff fa 90 21 00 01 ........ .....!.. 0010 02 00 02 01 00 00 00 00 71 37 00 00 00 00 00 00 ........ q7........ 0020 00 00 00 00 00 25 22 b7 d2 ea 00 00 00 00 00 00 .....%". ........ 0030 00 00 00 00 00 00 00 00 00 00 00 00 ........ ..... 0000 ff ff ff ff ff ff 00 30 ab 02 87 df 90 22 00 01 .......0 .....".. 0010 0a 65 01 7f 0a 65 01 7e 04 00 42 24 54 44 4d 41 .e...e.~ ..B$TDMA 0020 43 46 47 20 72 74 65 74 68 30 20 73 6c 6f 74 20 CFG rtet h0 slot 0030 30 20 32 30 30 3b 69 66 63 6f 6e 66 69 67 20 76 0 200;if config v 0040 6e 69 63 30 20 75 70 20 24 49 50 41 44 44 52 20 nic0 up $IPADDR 0050 24 4e 45 54 4d 41 53 4b 5f 4f 50 54 0a $NETMASK _OPT. ------------------------------------------------------------------------------ Return on Information: Google Enterprise Search pays you back Get the facts. http://p.sf.net/sfu/google-dev2dev _______________________________________________ RTnet-developers mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/rtnet-developers
