Porting onewifi on RPI:

...

This step by step guide provides detailed instructions to assist the RDK-B community

...

in porting the OneWifi component to the RPi4 reference platform

Tip

It is recommended to use the rdkb-2023q2-dunfell release as the base for porting OneWifi, and to integrate this release on top of the System-on-Chip (SoC) SDK. However, the documentation is applicable to Kirkstone release too

OneWifi

Platform-Specific Flags:

64-bit build support:

...

At present, support for 64-bit platforms is limited. However, the RDK team provides support for 64-bit builds on RPi4 platforms, with full integration of OneWifi. Many alignment issues and warnings that were previously treated as errors have been resolved in this support.
