MODULAR SGDMA burst read issue

Hi,

Descriptor prefetching is not essential, with our software descriptors processing, it's better with no prefetching.

I don't want to put a nios softcore because on the other side of PCI bus there is our main processor which handled the descriptors processing and high layers network protocol stacks. And I would minimize FPGA ressources...

We already acheive quite a lot of work with the ACDS SGDMA, our application (NIC board) is working but we have some random problems (perhaps software issue...). But our descriptor processing with ACDS SGDMA is not efficient due to SGDMA core specifications.

If we couldn't get better yield, we will start with your SGDMA. In this case, I could give you our feedback if you are interested.

In your last message, you talk about a SGDMA bug list, this is an official list? It could be very interesting to see it!

Thanks
