Workaround
Avoid faulty configurations with more than gSyncNodeMax nodes configured to
be transmitter of sync frames.
FlexRay_AI.066 Time stamp of the wrong channel may be used for offset
correction term
Description:
In case the temporal deviation (= time between primary time reference point and
action point offset) is different for channel A and B and the values have the
following combination
•
•
Scope:
The erratum is limited to the case where both channels are used and if there is
a large difference in the propagation delays on channel A and B.
Effects:
In case of the described relation between measured deviation values on
channel A and B the calculated offset correction term may have an error of
maximum the difference between the two deviation values. Thus, the error of
the local time of the node is limited to the difference of the temporal deviation
values of both channels.
Workaround
For dual channel FlexRay systems sync frames have to be transmitted on both
channels. In practice, the propagation delay between two nodes is expected to
be nearly the same on both channels. If this is not the case, the channel
depending parameter pDelayCompensation[A/B] (GTUC5.DCA, DCB) has to be
used to compensate the different propagation delays. With a correct adjustment
TC1797, EES-AC, ES-AC, AC
greater than or equal zero on one channel and negative on the other
channel
the channel with a relative deviation value greater than or equal zero is
choosen for offset correction term calculation instead of the negative value.
