In addition to my above mentioned question, please also comment on what should be the value of mux (I am setting 0x3210) and what should be the value of fpga_filename,
Please again note that I want to use 2 RFX2400 cards with one USRP1, and 2 rx streams will be there each through RX2 antenna of 2 RFX2400 cards and there will be one tx stream through any one of these cards.
