Re: [Discuss-gnuradio] Usrp2 and Agere ET131x compatibility

OK, we got the driver to compile, and spent some time trying to get the card to talk to the USRP2. If you try enough times, it sort of runs, but with a lot of noise. It has the same behavior when running through an ethernet switch. It turns out that the card and/or driver has some weird sort of data corruption which puts errors in nearly every received packet. We also got a lot of syslog messages which were warnings from the driver.

When I tried to connect the card to my router and do normal TCP/IP over it, it can't even get an IP address from DHCP successfully.

Basically, I think that the kernel drivers are simply not working, so there's no hope of getting these cards to connect to a USRP2 properly if they can't connect to anything else either. The fact that this driver has not been included in the main line kernel even though the chipset has been out for a long time (its no longer even owned by Agere -- it was bought by LSI) tells me that there are much deeper problems.

There are much better supported interfaces available. If you are using a laptop with this chip in it, I would suggest buying an ExpressCard (next generation of PCMCIA) GigE card with a Marvell chip in it. They should be less than $50.

I use dkms to auto compile; here is my dkms.conf:



Incidentally, a motherboard with the built-in Agere card seemed to work,
but not the pciexpress card.

Hi, guys

I have two questions:

- My laptop has AgereET131x chipset but it works perfect on Ubuntu8.10.
  Then, wonder why I fail to find USRP2 by the 'find_usrps' command?
(I see the chipset 'bad'
here(http://gnuradio.org/trac/wiki/USRP2GigEReports), but it looks like
that the linux and ET131 have some problems, not USRP2 and ET131)

- Granted that the compatibility issue exists, do we have any progress
on the latest source code of GR or on the USRP2 firmware?

I went out and bought a card based on this chipset so that I could
figure out the problem.  Unfortunately, I can't even get a driver
compiled for it, since the driver seems to not be in the mainline kernel.
