Hi all,

I'm trying to get a MIMO setup working using USRP2s with the UHD
drivers. I have a PC with 2 gigabit Ethernet interfaces, and a USRP2
connected to each.

My problem is that I can't change the USRP2 IP address so that the two
devices have different addresses. I can set the IP address in the
motherboard EEPROM using usrp_burn_mb_eeprom, and I can see the updated
IP address reported when I run uhd_usrp_probe, but the IP address the
USRP2 answers to is still

Power-cycling the device has no effect, nor does trying another PC in
case of any address caching. I've tried with UHD firmware&  fpga images
built myself from the latest git, and also with the 01/09/2010 release.

I've seen on the mailing list archives that some people have had success
with MIMO and UHD, and I haven't found any reference to IP address
problems. I must be missing something. Could anyone help please?

Thanks in advance,
