MySQL replication error from 5.5 -> 5.6

i was now searching the whole web but can't find any solution for my problem. I have an MySql Server, this is my Master and installed Version is 5.5.

My Slave has Version 5.6.

Show Slave Status on the Slave says that everything works well but i got some errors in the logs and no data will be replicated from master to slave.

 [Warning] Neither --relay-log nor --relay-log-index were used; so replication may break when this MySQL server acts as a slave and has his hostname changed!! Please use '--relay-log=***-relay-bin' to avoid this problem.

This status looks fine but when i add some data to the master nothing happend to the slave. I read a lot and the devs from mysql says that an replication from 5.5 to 5.6 is possible... So what did i do wrong ....

i think it is a problem wit @master_binlog_checksum... but how can i handle this?

i also deactivated the check

mysql> SHOW VARIABLES LIKE '%check%';
