Ah, OK, this one did the job :) Thanks!

To be honest, I even am not sure that I am doing things right, following the
settings a guy posted in the forum. There the path to the fpga file is
entered as an option into the osmo block. My problem is, I am a radio guy,
not a Linux guy - I know that the whole sw support is very beta and in a
growing process, but collecting small pieces of information from a confusing
forum and not knowing if valid or outdated, this is not exactly the way that
brings me to success :-)
        
At the moment I can load the FPGA from the command line (and the LEDs start
flashing then), but not out of grc. Of course there are errors, and I can
repeat the procedure and post them, but at the moment I guess that I simply
do some basic stuff totally wrong.
