At this point I have
reg [31:0] prtCycles;
wire [31:0] prtCycles_sr = 50;
wire prtCycles_ch;
setting_reg #(.my_addr(164)) sr_0
(.clk(radio_clk),.rst(radio_rst),.strobe(set_stb),.addr(set_addr),.in(set_data),
.out(prtCycles_sr),.changed(prtCycles_ch));
Then in b200_impl.cpp, I added the lines
_local_ctrl->poke32(TOREG(164), 131);
uint32_t reg_res = _local_ctrl->peek32(TOREG(164));
UHD_LOGGER_INFO("B200") << "Register value : " << reg_res;
I had hoped that this would output the output of setting_reg, which
should be prtCycles_sr, so 50. however I don't see this, instead I see
"Register value : 0." It feels that the poke32 method should let me
change the value of a register, could someone provide some advice on
how to change the reg value from the host with poke32?

Hi Dario,
Also I suggest using MyriadRF PPAs (e.g. like in gqrx installstion guide
here http://gqrx.dk/download/install-ubuntu). They always have updated GNU
Radio version which works with UHD from Ettus PPA.
