I have turned off the DMA on the Ethernet inside Xilinx Platform
Studio, do the method of editing the firmware have any relevance here?
In the HW sense, DMA is a superset of the FIFO functionality. So, even
if the HW is still buiklt with full DMA support, you can configure the
driver (via the auto-copnfig.in edit I mentioned) to only use FIFO mode.
It's jsut a way to quickly revert to FIFO mode without rebuilding the HW.
at least now the communication seams to work, I can ping in both
directions and use ftp and telnet from my host, thanks for the help!
OK, I'm glad it got you going.
What needs to be done to make DMA work correctly?
I'll need to look into this, and run some tests here. Will keep you posted.
