I would like a copy of your driver code and instructions on how to use it, if possible.
Thanks for your help,
Zen

Ok, so now you get to decide whether to use the sysTempeDma driver code that's provided with the mv6100 BSP (your code is then specific to the MVME6100 board), to install my driver into your BSP and write your code to my generic sysDma interface, or to port Till's RTEMS code and use that instead.

Note that my API only works it you're doing a memory-to-memory transfer, it doesn't provide a way to read data out of a single register into sequential RAM.  Let me know if you want a copy.
