The transfer length is 3 16-bit words, not 6 bytes, use sizeof()/2

You'll be interrupting very frequently, consider a bigger buffer.

Ending in the default handler suggests that your IRQHandler isn't linking properly, are you using a .CPP file, or C++ syntax (compile as if). If so you'll need to address name mangling, use extern ''C''

If there is no interrupt at all, look at the DMA flags, errors
