for my project i am using the Zedboard and FMCOMMS2. I am working with Gnuradio and Python. Now, I am trying to set the hardware gain for the FMCOMMS2 source. During some tests i recognized, that the hardwaregain is not set correctly. This wrong setting occurs only when i switch on the Zedboard and start the programm the first time. But when I restart my programm, the hardware gain will be set correctly.
I am not sure if this error depends on the Gnuradio settings or if a variable is not set correctly at the beginning. Furthermore, the gain mode is set to manual.
Thanks for your help.
