The FPGA build is not compatible with the host code build

GNU Radio

Hi all,

I’m a new user of GNURadio and USRP. I used the script “build-gnuradio”
to
download the source and have installed them all.But when I tried the
“uhd_fft”, the terminal showed as belows:

Linux; GNU C++ version 4.6.3; Boost_104800;
UHD_003.008.002-168-gddae9468

– Opening a USRP2/N-Series device…
– Current recv frame size: 1472 bytes
– Current send frame size: 1472 bytes
RuntimeError:
Please update the firmware and FPGA images for your device.
See the application notes for USRP2/N-Series for instructions.
Expected FPGA compatibility number 11, but got 10:
The FPGA build is not compatible with the host code build.
Please run:

“/usr/local/lib/uhd/utils/uhd_images_downloader.py”
“/usr/local/lib/uhd/utils/usrp_n2xx_simple_net_burner”
–addr=“192.168.10.2”

I followed the instruction as above. However, the problem still exists.
I
noticed that the images it downloaded is
“uhd-images_003.008.002-157-gbe03e694.zip”,which seemed to be not
compatible
with UHD_003.008.002-168-gddae9468.

Can anyone tell me how to figure it out ? which of the files on
files.ettus.com:/binaries/images/ is number 11?

Thanks very much.

Yue

This is unusual. Not sure how that slipped past. I’ve got a query in to
Ettus engineering to see where the slip is.

Also, just to confirm, you did power-cycle the N210 unit after burning
new firmware?

Hey,

we did update our FPGA images on the N-Series for the next upcoming
release. You will need to update the device according to our manual
(USRP Hardware Driver and USRP Manual: USRP2 and N2x0 Series). This change was
necessary (among other things) for the N-Series to support our new UBX
daughterboard.

Note that you might have to git pull again – we didn’t properly sync up
code and images release last week, so you might be stuck between the
code change and the images update. After git pulling, run
uhd_images_downloader.

Cheers,
Martin
