So because of memory fragmentation, there may not be MB of contiguous memory on your system. For prototyping, you might be able to get away with just booting up with less memory. Hello, I have been reading your article about how to transfer data from a FPGA board to a computer and I might be pretty interested by your researches. Home My CV Blog’s home. Step two, what does the dev board’s creator provide? It’s mostly find something similar, and then mod it until it works.

As for the Linux side, there is no work at all. No kernel programming will be necessary either.

There are likely some nice examples of pcie drivers in the “driver” directory. Well yes, the license would apply, but that doesn’t mean that we have to give it back to the Linux kernel. All that is needed, is to compile a certain kernel module against the headers of the running Linux alfera.

Inferred RAM and mux.

Such as if you’ve connected the driver to user space through sysfs then handling people opening, reading and writing the relevant files. Then you just fill in the blanks. If you got your UIO driver to bind to your device then you should be able to mmap the device to get access to it’s memory. All this holds for a 1x connection as offered by Spartan-6T. Maybe with configurable word widths? You just need to interface with the PCIe comms layer of linux.


Do you have terminal access? Verilog source code is not published, as the IP core is licensed against fees. I mostly focus on FPGA system level design and high speed data paths and controls. Become a Redditor and subscribe to one of thousands of communities. For prototyping, you linuc be able to get away with just booting up with less memory.

This will be pretty simple if the kernel’s are similar versions. I would like to use a fpga board in order to send information that has been calculated to another computer with a pcie bus.

You could always linud what you learn and write a nice blog post in your spare time, doing it all again or something.

PCI Express Reference Designs and Application Notes

FPGA submitted 1 year ago by hardolaf. Written By eli on May 26th, This looks interesting https: Written By Smith on February 27th, Having a way to push data from the PC to the FPGA and pull other data back would be so useful not only for testing, but it could also be the actual application. If it helps, I’m pciw sure any mod to the linux kernel tree has to be released as open source. Its old, but it’s still a very useful guide.


This should have a PCIe driver included.

Depending on what already exists. I should have been more specific.

PCI express from a Xilinx/Altera FPGA to a Linux machine: Making it easy

The usage idea is simple: I don’t need, or care, to test those tasks other than to confirm that DMAs work appropriately at this time.

You can I believe bypass this if you write it as a kernel module.

This altea section is closed. I’ve been trying to make sense of all the poorly documented resources that people have told me about and that I’ve found I found that same link early today.

Your advice is very much needed.
