Hi Peter,

From my experience, geetting the Arria V Starter Kit board going was a fair amount of work but it should not have been.

I was on a Linux system and had to learn Linux device driver by taking various examples and comming up with something that worked.

On the Windows environemnt I would think it should be easier since with the Juno driver.

I'm not sure about the 79 devices unless they actually exist.

I did some work on a PC and found it useful using some of the existing tools to enumerate the slots after POST /BIOS which will say that

your card has trained and is seen in the slot ... I had some trouble with various slots even at Gen1 due to slot width.

I did run the sample application doing DMA and it measures write / read performance ... I can check whatthat was. It would have been the sample DMA application.

Let me try to digest your points and get back to you.

Bob.
