Hi,all!
I just use the two machines( rtlinux+rtl-lwip installed) for
communication I write a simple application to test the time of the sending
and receving. First ,Node A send package to B at periodic intervals, then
exchange. I use the gethrtime() to record the “sending time ” and “
receving time”. There are serious drifts of time. I think the problem may
be cause by the drift of the node’s CLOCK_REALTIME. The attached PDF file
describe the whole test process and the result in details. Can anyone take
a look at the report? Any suggestion would be appreciated!
Thanks in advance.
Best regards
Liu kun
