Hi embedded people,
we have a PaSemi (PA6T-1682) CPU is use with Linux and CFE. I wonder if
anybody has experience with the DMA engine of the device. Some examples or
an API would be particularly usefull.
Thanks,
Samuel Zahnd

The network driver uses the DMA engine, besides that there's not much
example code out there.
The DMA has alot of features, just what are you looking to do? Just DMA
copy offload, or other functions?
