Failed to setup CUDA_accelatered LDPC

[lingyan98]

I downloaded and set up the sionna-rk project in Jetson Orin AGX (gnb, 5G function, etc) and another Ubuntu laptop (nr-ue). When I run the OAI with CPU, the ping test between UE and gNB is successful. However, when I change to the CUDA_LDPC in the OAI gNB. The connection failed.

Hi @lingyan98,
we’ve just released SionnaRK v1.1 today. It now is now uses a significantly newer OAI version. Could you please upgrade to the latest release? Sorry about that; unlucky timing :-)

[lingyan98]

Hello @SebastianCa
Thank you for your reply! I upgraded to the latest release. And running the commands follow the "Software-defined End-to-End 5G Network" tutorials. And input the USRP serial in the .env file. But the others some other errors happend
