Thank you Marcus again,
I changed device address, in both places, but the same problem appears. I
see that it loads now 4rx image, but the problem remains.
self.uhd_usrp_source_1 = uhd.usrp_source(
device_addr="fpga=usrp1_fpga_4rx.rbf",
stream_args=uhd.stream_args(
cpu_format="fc32",
channels=range(1),
),
)
