Hello Mark,
Thanks for your prompt answer.
We are using the ADC1x3000-8 in the ZDOK 0.
The first thing we did was to run the bof file you mentioned, just
after downloaded.
I just did it again with the same result:
root@roach-laptop:~/Desktop/workspace# ./spectrometer.py 192.168.1.10
-b r_spec_2048_r105_2010_Jul_26_1205.bof
Connecting to server 192.168.1.10 on port 7147... ok

Programming FPGA with r_spec_2048_r105_2010_Jul_26_1205.bof... done
Configuring accumulation period... done

Setting digital gain of all channels to 4294967295... done
We got the same spectrum I mentioned in my last email and after a
while we got error:
Exception in Tkinter callback

I am using the normal Ethernet port to connect to the ROACH (not the 10GBE).
A red led lights up on the roach when I run the script.
Also a green light blinks about two times per second.
After the script crashes with the 'runtime' error the leds on the
roach continue doing the same thing.
