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 Raspberry Pi 4 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 |
