```
Note that in tags 2025.w06 and prior, the FHI72 driver used polling to wait for
the next slot. This is inefficient as it burns CPU time, and has been replaced
with a more efficient mechanism. Nevertheless, if you experience problems that
did not occur previously, it is possible to re-enable polling, either with
`build_oai` like this
./build_oai --gNB --ninja -t oran_fhlib_5g --cmake-opt -Dxran_LOCATION=$HOME/phy/fhi_lib/lib --cmake-opt -DOAI_FHI72_USE_POLLING=ON
or with `cmake` like so
cmake .. -GNinja -DOAI_FHI72=ON -Dxran_LOCATION=$HOME/phy/fhi_lib/lib -DOAI_FHI72_USE_POLLING=ON
ninja oran_fhlib_5g
## Configuration
RU and DU configurations have a circular dependency: you have to configure DU MAC address in the RU configuration and the RU MAC address, VLAN and Timing advance parameters in the DU configuration.
