[USRP-users] Re: X310 FPGA errors

Jonathon, Marcus Usually, when something goes wrong, I'm getting an error like this: [x300_fw_ctrl.cpp:53] [X300] 192.168.40.2: x300 fw communication failure #1 EnvironmentError: IOError: x300 fw poke32 - reply timed out [1]193622 abort (core dumped) Marcus, I'm not sure which part of the c

[USRP-users] Re: UHD 4.1 memory leak?

Copied and pasted some code to reproduce the issue. Hopefully it makes some sense... receiverLoop1 is increasing mem usage, receiverLoop2 does not. Btw, set_rx_iq_balance function seems to be inverted, setting it to false on the E310 reduces spectrum images more than 50 dB, while true reduces on

Hi list, I occasionally, unpredictably, get FPGA-related errors. Usually some sort of FPGA timeouts, so I have to reset the USRP after these errors, which is rather inconvenient. The software is C++ using the UHD 4 multi-usrp API. Without going into too much detail, I wonder if there is anyt

This looks like it might be a bug to me. Sent from my iPhone > On Nov 23, 2021, at 6:00 AM, Skorstad, Jørn wrote: > >  > Hello, > > I have some trouble using the UHD 4.1.0.2 library. I am using RFNOC blocks > RADIO and DDC, and setting up an RX stream using graph->create_rx_streamer. >

[USRP-users] Re: Trouble with TwinRX frequency tuning

Hi Emanuele, I'm not certain, but it looks like the command buffer to the radio may be filling up such that when it's full, you receive the "no response packet" error. Configuration commands such as set_rx_frequency are inserted into a command FIFO on the FPGA. One thing that can cause the entire

[USRP-users] UHD 4.1 memory leak?

Hello, I have some trouble using the UHD 4.1.0.2 library. I am using RFNOC blocks RADIO and DDC, and setting up an RX stream using graph->create_rx_streamer. The receiver loop is running in its own thread doing something like this (simplified): uhd::stream_cmd_t stream_cmd(uhd::stream_cmd_t::S

[USRP-users] Re: Trouble with TwinRX frequency tuning

Hi Marcus, thank you I tried both changing the command-time (up to 1 second) and using UHD version 3.15.0.0. The application still crashes with the same error. terminate called after throwing an instance of 'uhd::io_error' what(): EnvironmentError: IOError: \[0/DDC_0\] sr_write() failed: Env
