Hello,
I have followed the general instructions for building and running the Yocto ecosystem on the board. For the communication between the Atom and the FPGA, there are some files under a
demonstration folder on the CD, and it is quite enphasized that this API is for demonstration and test.
It makes me think that these are not for "production" usage, as they are possibly not properly optimized for high performance usage. Hence, I think that I should write my own modules for low level communication. But it appears that they doesn't even give their source codes.
What is he best way to access the PCIe for high speed communication between the Atom and the FPGA on this board? I'm not sure how is the best way to do that.
Best regards

Hi Guilherme,
It's true that the demo is likely not optimized, as the idea is for users to have a reference to communicate between the CPU and the FPGA.
On the other hand, it doesn't necessarily indicate it's not ready for high performance usage, but it really depends on your definition. Perhaps it would be better if you have a number measured from practical result for comparison.
Could you point out which part of source code is not given ?
Thanks,
