I have done that but they did not get copied to the /libdata directory.

On examining the radeok_cik.c file in the cik_init_microcode() function (or something like that) it looks for the KAVERI*, then the kaveri* files. As far as I can tell the kaveri* files are the new firmware. You have to have all the kaveri* files in the libdata directory, so that it will use all the new firmware, otherwise it complains that old and new firmware is being mixed. Thanks for the response.
