Errata Sheet
Functional Deviations
a worst case scenario, if the whole cluster is drifting away too fast, the
integrating node would not be able to follow and therefore abort integration.
Workaround
Avoid configurations with pMicroInitialOffsetA,B equal to zero. If the related
configuration
constraint
of
the
protocol
specification
results
in
pMicroInitialOffsetA,B equal to zero, configure it to one instead. This will lead to
a correct initial rate correction value, it will delay the startup of the node by only
one microtick.
FlexRay_AI.093 Acceptance of startup frames received after reception of
more than gSyncNodeMax sync frames
Description:
If a node receives in an even cycle a startup frame after it has received more
than gSyncNodeMax sync frames, this startup frame is added erroneously by
process CSP to the number of valid startup frames (zStartupNodes). The faulty
number of startup frames is delivered to the process POC. As a consequence
this node may integrate erroneously to the running cluster because it assumes
that it has received the required number of startup frames.
Scope:
The erratum is limited to the case of more than gSyncNodeMax sync frames.
Effects:
In the described case a node may erroneously integrate successfully into a
running cluster.
Workaround
Use frame schedules where all startup frames are placed in the first static slots.
gSyncNodeMax should be configured to be greater than or equal to the number
of sync frames in the cluster.
