USRP X310 PCIe connection problem #109

Open flow233-ai opened 1 month ago

flow233-ai commented 1 month ago

Hi everyone. I have encountered a problem have not found a solution on the internet so far. The settings is shown as follows:

We use PCIe for the connection between our PC and USRP X310. And the Linux system of PC is Ubuntu 20.04. We use radioconda to install gnuradio 3.8 and UHD 3.15. And the Python version is Python 3.8. And we install the

Then we use “uhd_find_devices” and the connected USRP can be detected. But then we use “uhd_usrp_probe”, the following errors occurred:

“Error: RuntimeError: x300 impl: Could not initialize RIO session. A memory allocation failed. Try again after rebooting. (Error code -52000).”

I have not found a solution on the internet so far. I wonder if this is due to the radioconda installation or some problem related with FPGA images.

Many thanks.

I've solved this problem. The solution is to use "sudo uhd_usrp_probe", to access the correct bitfile.
