This is just for the E-101, our other boards have really good Linux
support (M-501, etc). Windows was a higher priority for the E-101
because it's more of a board we use for training and most of our
customers do their FPGA development on Windows whereas the PCIe
M-modules are geared more toward the HPC server market so it was a
higher priority for them to run well in Linux..

Yeah, our APIs are very similar between the E-101 and M modules the
only difference is that the E-101 has much better support for Windows.
If Yuri does his development on Windows it will be easy to port it
over to the M modules on Linux...

For now I think the best thing is to do PoC in Windows on the E-101 so
he doesn't waste more time on trying to get the Linux code working.
This can be done by just synthesizing code and running/testing using
our PicoUtil software in Windows just to make sure the logic runs on
hardware. In the meantime I can set him up with remote access to a
Linux system here with an M-501 for the final implementation... Does
that work?
