Hi Josh,
Sorry, didn't see your e-mail until getting the digest today. Thanks for
the fix!
Cheers,
Adam
A fix has been pushed (the eeprom offset was wrong). -Josh

Hi Marcus D. Leech,
Thank you for your response.
I never use the peak hold button on this machine because I cannot click any
buttons on the screen begin the program running, it is also dead as the
same time. As I said before, I cannot do nothing

I am also interested in using the cable. We bought 10+ USRP2 and several
MIMO cables, hoping to set up a MIMO network. But I have not figured out
how to do that.
I read through Josh's UHD MIMO announcement:

But
The serdes cable does not currently work with UHD other than to share
ref clocks. I am currently (as I type this email) working on the FPGA
routing logic to use the mimo cable with UHD. Don't hold your breath,
but I am attempting to get it working before the holiday next week.

Sorry, I am using raw-ethernet driver. I saw those APIs for UHD. Does it
apply to raw-ethernet driver use as well?
I believe so, except that the set_antenna call takes an integer 1 or 0.
I would use trial an error to determine the antenna mapping. -Josh
Hi Josh,
Wow~ I thought the cables would need to be thrown away since we don't know
how to use them. ;)
Thanks a lot!!! I'm looking forward to your implementation!

Hi everyone,
I also have the same question about USRP2 with MIMO Cable. I found from the
forum that it should program the SD card with new firmware, but I don't know
where to find the firmware code on the gnuradio wiki.
Doee anyone have any idea about this. Please let me know, thanks in
