### Running OAI gNB with USRP B210/FHI72
When running the gNB **with FHI 7.2**, it is not necessary to provide the `--nrLDPC_coding_aal.dpdk_core_list` argument
since the core list specified for FHI 7.2 will be used for DPDK.
If it is provided, the AAL core list wil be ignored.
Example command:
```bash

# Known Issue(s)
## BBDEV CPU Usage
When running the E2E setup (this applies to both USRP and FHI72), BBDEV may not be using the list of CPU cores as specified by `nrLDPC_coding_aal.dpdk_core_list` accordingly.
This is an issue under investigation, and subject for future fixes.
In the meantime, we recommend allocating idle, and isolated CPU cores in the configuration for BBDEV.
## Potential Low Throughput
The current implementation has been tested to work in an end-to-end setup and is functional.
