This might be because you questions are not allways very clear. They also sometimes seem to indicate that you didn't read the documentation that is there.

Do you know how the usrp and the fpga are used in the gnuradio project. Do you know how the > I am doing some work on the fpga, so more or less, the work will be with the > CCS. What is the CCS?

Gnuradio does not work by rebuilding the fpga from python. The firmware is fixed. You use python code to connect gnuradio software blocks which do allmost all of the processing (on your CPU. python is also used to instruct the usrp driver to put the fpga in the right mode. (receiving, transmitting, decimating, tuning daughterboards) The functions in the firmware you can find in the wiki and the usrp documentation. A search on the mailinglist archives also does wonders. People here are willing to help. But if your only question is. Where are the docs of everything?
