Hi, I try to do some basic performance test of RTnet What correspond exactly TDMA_CYCLE and TDMA_OFFSET ?
here is a test with TDMA_CYCLE=500 and TDMA_OFFSET="50" ip address 192.168.10.3=c0a80a03 Warniinterval = 500 ng: loading rt_cpacketsize = 58 Roundtrip = 504us (min: 504us, max: 504us) Roundtrip = 23902us (min: 504us, max: 23902us) Roundtrip = 502us (min: 502us, max: 23902us) Roundtrip = 24100us (min: 502us, max: 24100us) Roundtrip = 500us (min: 500us, max: 24100us) Roundtrip = 500us (min: 500us, max: 24100us) Roundtrip = 24099us (min: 500us, max: 24100us) Roundtrip = 498us (min: 498us, max: 24100us) Roundtrip = 26097us (min: 498us, max: 26097us) Roundtrip = 496us (min: 496us, max: 26097us) Roundtrip = 26097us (min: 496us, max: 26097us) Roundtrip = 497us (min: 496us, max: 26097us) it's no real-time When a try whit default setting the round trip is = 7000�s but it lost 1�s evry seccond. when I launch rtai the one calibration is not correct : ***** STARTING THE UP REAL TIME SCHEDULER WITH LINUX ***** ***** FP SUPPORT AND READY FOR A PERIODIC TIMER ***** ***<> LINUX TICK AT 100 (HZ) <>*** ***<> CALIBRATED CPU FREQUENCY 33000000 (HZ) <>*** ***<> CALIBRATED TIMER-INTERRUPT-TO-SCHEDULER LATENCY 2515 (ns) <>*** ***<> CALIBRATED ONE SHOT SETUP TIME 485 (ns) <>*** ***<> COMPILER: gcc version 2.95.3 20010319 (2.95.4 CVS + prerelease/franzo/2001 0912)*** for a PowerPC 133 Mhz should this modify my RTnet test ? Thanks a lot !!
