View all threadsMIMO cable support
Hi,
I started to use usrp2 + wbx with uhd last week. And i install uhd and
burned required images to sd card.
At the end i can take samples from usrp2 as i expected. Thanks for your works.
But i want to try mimo cable with my 2 usrp2s to receive sync data.
I read some manuals but i dont understand exactly what i need to do.
Can you explain about configuration with details for mimo cable support, please.
For example;
How should i use usrp2_txrx_uhd.bin and packet_router.bin?
Is there any sample program for testing mimo?
Thanks...

yes, until the mimo-cable support becomes mainline, use
http://www.ettus.com/downloads/uhd_images/experimental/UHD-mimo-cable-support/
Is there any sample program for testing mimo?
Not yet. The docs above should help to clarify the usage though.
Also, you could put an app together in GRC rather quickly with the
multi-usrp source/sink blocks.

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?

The packet_router branch was just uploaded to the github mirror.

Correct

Correct
After building and installing the host code, and writing the SD card,
The USRP2 should appear to function as normal. Make sure
uhd_find_devices finds your device.

Hm ...
I do
/> git branch --track packet_router
git checkout packet_router
git pull
/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?

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