Hello,
thanks for the fast reply. In the example shown I limit myself
to a DMA controller and two 64-bit memories which I control
via a self-made Avalon master (not burst capable, does that matter ?).
The DMA controller actually does not even finish correctly (busy bit
stays on), when I execute a word transfer (in burst mode).
I wonder if it is possible to let the DMA controller fetch
data in 32-bit burst word mode over the PCIe bus or do I always have
to use 64-bit boundaries. In not burst mode 32-bit transfers work, but
then every transfer is a PCIe packet which degrades performance ...
(I'll post this question in a seperate thread)
Kind Regards,
Jon
