Hi Kunal,
Can you take on the Linux driver for the
core? You can start with our reference from the LwIP, I can post that to the
forum here or on my firm’s development forum.
I will have the core released then prior
to the end of the month on my firm’s website, along with an example
implementation spec. I’ll send more details as soon as its online.
Thanks

### Free Ethernet Core - Any Interest?? ###
Hi
Steve,
I am intrested in the Ethernet IP core. Please provide me more deatails.

Hello
Folks,
My engineering firm is developing several Microblaze IP cores based on
some of our own IP and some of the opencores IP.
One of the cores which we have created is an OPB to Wishbone interface.
This interface supports master and slave devices allowing Wishbone
DMA/Mastering within the Microblaze.
We have created an instance of the OpenCores's 10/100 MAC and have this
now fully operational within the Microblaze.
We have also created a driver that uses the LwIP stack and the Xilinx
MicroKernel. Haven't yet made a linux driver, but this shouldn't be any
trouble using our reference code.
I am tossing this out here because I have been considering releasing two
versions of the core.
The first version would provide full-speed DMA transfers of packets
across this OPB bus. This version would be a "pay" core, but will be
significantly cheaper than any others out there.
The second version we could release is a complete free core, but we
would "slow-down" the DMA transfers somewhat within our
OPB<>WISHBONE
translator.
I'm sure you will find this core smaller and faster than the Xilinx
EMACs, plus it won't "lock-up" after a time period like Xilinx's
protection scheme in their Mac.
I'm happy to release the "Free From FLE" version if some folks are
interested in using and are interested in creating a Linux Driver which
can be contributed back to the community.
Are there any takers?
Thanks for reading
