  The cyclic codes with parity check polynomial the reciprocal of the
characteristic polynomial of the Fibonacci recurrence over a prime finite field
are shown to have either one weight or two weights. When these codes are
irreducible cyclic we obtain many counterexamples to the conjectural
classification of two-weight irreducible cyclic codes of Schmidt and White
(2002). When they are reducible and projective their duals are uniformly
packed.
