HI

I am presently trying to work with USRP N210 with a SBX daughter board
connected to a Host laptop with Ubuntu 12.10 installed.This laptop had a
version of GRC and UHD installed when I got it.
But even though I was able to run some uhd example programs like tx_waveform
and uhd_siggen_gui.py iw as unable to run uhd_fft.py directly from the uhd
utilities. The error showed that some libraries are missing and hence I
decided to update the uhd,grc version. 
However, the USRP with the daughter board was not getting recognised with
uhd_usrp_probe command. So after the googling I found some people suggesting
that fw on the usrp needed to be updated too.
Though I have burned the latest images of usrp_n210_fw.bin and
usrp_n210_fpga_r4.bin  into usrp ,still it is not working. I get the foll
error message: 

Error:Runtime Error
Please update the firmware and fpga images for your device
Expected protocol compatibility number [7 t 11], got 12
The firmware is not compatible with the host code build.

I am stuck and google is not providing any different answers. how do I know
which is the compatible version for the current uhd and GRC
Any help will be greatly appreciated.
 
Thanks 
Gayathri
