There is a forum post, in which the project explains quite explicitly on how to use the DMA with Automatic Memory Management. Can you check the project in this post and see if it helps you understand the error?
The APIs work differently for the DMA with Automatic Memory Management.
Eg: The LoadINEP needs to be used with the argument NULL (for data buffer) when you simply want the data to be sent. If you want to change the buffer being pointed to, use the LoadINEP with the proper buffer pointer.
