hi,
I think this is very easy to answer for you but i really don't understand what
is the procedure for mimo support.

I burned the usrp2_txrx_uhd.bin to sd card and then usrp2 does not load cpld and
fw as i understood from usrp2's leds.

I don't know how can i get fpga image and fw image to burn sd card.
Please help...

Hi Josh,
I think i solve my problem. I misunderstood your first explanation. Sorry...
Please check my configuration. These steps are right? I can get data from my
usrp2 now (with below configuration) but i don't try mimo yet.
Step 1) I download the packet_router branch and build it as host.
Step 2) I burned sd card with usrp2_txrx_uhd.bin as FW image and
packet_router.bin as FPGA image.

Hi all,

I can't pull the packet_router branch via the http repo. Is it mirrored
from the GIT repo or am I doing something wrong?

Regards,
Thomas

Hm ...

I do

/> git branch --track packet_router

/And it tells me

/From .

• branch  master -> FETCH_HEAD
  Already up-to-date./

Is the MIMO repo identical to the master repo or why are there no
changes between the master and packet_router repo?

Regards,
Thomas

git br --track packet_router <remote_name>/packet_router

which is probably just

git br --track packet_router origin/packet_router

The added changes to master since packet_router are of no consequence.

OK. I did this and now I get after "checkout" and "pull".

Is this OK for building or should I expect to see some changes listed?

Thomas

I dont know what you did. You need more git foo.

do this:

git remote update

#since you already made the branch
git co packet_router

#whatever it is, force it to be the packet router
git reset --hard 4d9b9ae7e9fe36bf7c1e2e60a37845e9cc4ecee3

Hi,

I deleted my local folder and did a fresh install and things seem to
work now as expected.

Thanks for your help.

BTW, is MIMO supported by GRC?

good to hear

By nature, its completely transparent. So everything should work. You
can use the multi or single usrp blocks.

hi,

after doing all steps which described below, i can find my devices with
uhd_find_devices. i connected 2 usrp2s together with mimo cable. and only one of
them connected to host(pc) with ethernet. the result is;
$ uhd_find_devices
linux; GNU C++ version 4.4.3; Boost_104000; UHD_0001.20101220140942.1

Hi,
Please help, i get errors when i run uhd_usrp_probe andrx_samples_to_file.
Details;

After build and install  packet_router(for host), burn images that supports
mimo, connect only one usrp2 to ethernet and

don't connect mimo cable anywhere, i get these results;
When i run uhd_find_devices and the result is
linux; GNU C++ version 4.4.3; Boost_104000; UHD_0001.20101221140638.1

Device Address:
type: usrp2
addr: 192.168.10.2
name:
serial: 00:50:c2:85:37:b8

but when i runuhd_usrp_probe, it returns error as
linux; GNU C++ version 4.4.3; Boost_104000; UHD_0001.20101221140638.1
Current recv sock buff size: 50000000 bytes

and sometimes it returns
linux; GNU C++ version 4.4.3; Boost_104000; UHD_0001.20101221140638.1
Warning:

After these errors i deleted related local folders then i build and install
packet_router branch again.

But i have already the same problems.
Is there any solution?

Thanks...

try power cycling? Different cable arrangements? How repeatable are your
results?

But sometimes when i run uhd_usrp_probe and rx_samples_to_file, they works correct. Most cases i got error messages. These errors can be related with my ethernet interfaces' configuration? Or maybe i changed usrp2s' eeproms(db or mb) somethings wrong?
These errors occoured after that i tried to connect both usrp2s to the host with their dedicated ethernet interface and at the same time i connected mimo cable. When i run uhd_find_devices at this configuration, found 4 usrp2s.

Thank you for your interest and sorry for my bad english :)
