• TSS Violation — transmission start sequence violation.
• Header CRC Error — cyclic redundancy check error in the
header.
• Frame CRC Error — cyclic redundancy check error in the
frame.
Frame End Sequence Error — less than 11 bits received.
•
Boundary Violation — frame received overlaps slot
•
boundaries (synchronous monitoring mode only).
Network Idle Time Violation — frame received with NIT
•
(synchronous monitoring mode only).
Symbol Window Violation — frame received within symbol
•
window, or symbol received outside of symbol window
(synchronous monitoring mode only).
Slot Overbooked Error — 2nd frame received with one slot
•
after a correct one (synchronous monitoring mode only).
Null Frame Error — null frame received within dynamic
•
segment (synchronous monitoring mode only).
Sync or Startup Error — sync bit or startup bit set within
•
dynamic segment (synchronous monitoring mode only).
Frame Id Error — mismatch between internal and received
•
slot ID (synchronous monitoring mode only).
Cycle Count Error — mismatch between internal and received
•
cycle counter (synchronous monitoring mode only).
Static Payload Length Error — unexpected payload length
•
within static segment (synchronous monitoring mode
only).
Since FlexRay errors occur infrequently it may be helpful to set the
oscilloscope to Normal trigger mode instead of Auto trigger mode. This
prevents the oscilloscope from Auto triggering while waiting for an error to
occur. You may need to adjust trigger holdoff to see a particular error when
multiple errors exist.
