FlexRay_AI.062 Sync frame reception after noise or aborted frame before
action point
Description:
In case noise or an aborted frame leads to the detection of a secondary time
reference point (STRP) and after this a valid sync frame is detected in the same
slot and the STRP of the valid sync frame occures simultanoeusly with the
action point, the temporal deviation value of the first detected STRP is stored
instead of the value of the correct STRP.
Scope:
The erratum is limited to the case of noise before reception of a valid sync frame
or a frame reception starting before action point is aborted and then a valid sync
frame is received in the same slot.
Effects:
In the described case a wrong deviation value is used for correction term
calculation. Depending on number of sync frames and other measured
temporal deviation values it may lead to an incorrect rate or offset correction
value.
Workaround
None.
FlexRay_AI.064 Valid frame detection at slot boundary
Description:
In case a non sync frame is detected to be valid simultaneously with the slot
boundary and in the following slot a sync frame is received, the temporal
