Hi Philips,
thank you for your answer. I will have a look to your git repository.
I'm not very good with linux kernel intrinsics but I will try to have
driver work with newer kernel.
If I succed, i will post my results.
Thank you !

Hi,
I've got several USRP E100/E110 with outdated Linux and Gnuradio
software on it. So I decided to build a Yocto image, more up-to-date and
succeeded in after several tries.
The new image boots and run a reasonable updated version of Linux and
Gnuradio.
But, because of Ettus proprietary kernel driver, I cannot connect to
FPGA and so the board is useless.
It's an open driver, just non of us remember how it works. I did find
the code:
https://github.com/balister/linux-omap-philip
The linux DMA architecture has likely changed, so the driver will need
work, but the code is out there. Let me know if you have questions, it
would be great to see these running. I'll answer as best I can. It has
been like 6-7 years since I last looked at it though.
Using it like an N-series is likely not possible. The fpga is connected
to the Overo via the GPMC (General Purpose Memory Controller).

My questions are:
- Did someone achieve to get an updated Linux base and Gnuradio
software, with working FPGA communications (whatever the method)
- Is it possible to get source code of Ettus kernel driver, as the
board is now End-of-life
- Is it possible to enable Ethernet communication pass-throughto
FPGA, a bit like in N series, in order to use it over Ethernet(not
standalone)
Regards!
Sebastien
