Hi all, Usually, DC will need a cycle time at 1ms or lower, but we don't need a cycle time that fast, we only need 20Hz ~ 50Hz, is that possible for DC?
For what I test on my driver (LAN9252), if the cycle time drop below 200Hz, it will unable to make the driver bring up from PREOP to OP, although the frame is still exchanging. Also, SM2 sync is possible to run at 20Hz ~ 50Hz, but can I measure the propagation delay between the drivers? Is the 0x900~ reg valid even if I'm using SM2 sync mode? I'm using Linux 4.14.67-rt40, IgH 1.5.2 w/ all unofficial patches. Thanks, Louie. _______________________________________________ etherlab-users mailing list etherlab-users@etherlab.org http://lists.etherlab.org/mailman/listinfo/etherlab-users
