Beta version ready!

The beta version has been tested on a Gullwing development board from Gennum. For testing purpose, one 8KB RAM is connected as a slave on the DMA wishbone. Two slaves are connected to the CSR wishbone.

First DMA transfer in both directions

A first bi-directional DMA transfer has been achieved on the Gullwing development board. The interrupt message generation (MSI) is also working fine.
