The IETF changed the algorithm a bit, and its not compatible with Bernstein's ChaCha. They probably should have differentiated the name to avoid this sort of confusion. You can find Bernstein's specification for ChaCha at https://cr.yp.to/chacha.html, and the test vectors for Bernstein's specification at http://tools.ietf.org/html/draft-strombergson-chacha-test-vectors.
