Hi,  I have USRP B210, and I need to write into user setting register in FPGA. Is any easy way to do this? For many other radios (B100, N2x0, E100) is implemented function set_user_register(). Why isn't implemented user_setting _core in B200_impl.cpp? . It is really important to me, because I have spend too many time with changing Verilog code, but its unusable without ctrl from host computer.  Thank you for answer. Petr

Dear Petr, interfacing with the registers is usually done via radio_ctrl_core_3000 on the third-gen devices like the B2xx. Which actual instance of that you want to use depends on which part of the B210 FPGA your settings register is connected – there's the _local_ctrl, and one radio_perifs[0,1].ctrl for each DSP chain in b200_impl .

Marcus since Petr is asking about user settings specifically I suspect he has enabled and connected his custom logic to the user_settings module in radio_b200.v. Can you confirm please Petr?. This currently lacks for B2x0, as Petr pointed out, access via the usual UHD API. -Ian On Tue, Apr 26, 2016 at 1:07 AM, Marcus Müller <usrp-users@lists.ettus.com> wrote: > Dear Petr, > > interfacing with the registers is usually done via radio_ctrl_core_3000 on > the third-gen devices like the B2xx. > Which actual instance of that you want to use depends on which part of the > B210 FPGA your settings register is connected – there's the _local_ctrl, > and one radio_perifs[0,1].ctrl for each DSP chain in b200_impl . > > Best regards, > Marcus > > > On 26.04.2016 06:23, Petr Prachař via USRP-users wrote: > > Hi, > I have USRP B210, and I need to write into user setting register in FPGA. > Is any easy way to do this?
