High-level Overview

We are pleased to announce the RDK-B Broadband Annual Release for the BananaPi R4 reference platform. This marks a significant milestone — our first annual release, consolidating the journey from the Q1 2025 board bring-up through the 2026 Q1 release into a single, comprehensive platform delivery.

Moving from quarterly releases to an annual cadence signals the platform's maturity and stability, giving operators, OEMs, and SoC partners a reliable, long-horizon foundation to plan their roadmaps and investments around.

Key Benefits of RDK8 for Broadband

  • Integrated IoT support built into the gateway

Includes integrated Barton support for Matter, Thread, Bluetooth, and Zigbee natively within the gateway, provided the appropriate hardware (radios) are also present.

  • Simplified field debugging and lower operating costs

The Remote Debugger feature streamlines field issue resolution, helping reduce truck rolls and lowering operator support costs

  • Wi-Fi 7 readiness with built-in MLO support

Prepares the platform for next-generation wireless performance with built-in Multi-Link Operation support for Wi-Fi 7 deployments.

  • Enhanced access control through MAC filtering

Introduces MAC filtering support, enabling maintenance of device deny lists for stronger access control and operational flexibility.​

LAN clients are not working after device reboot in Bridge mode

...

RDKBACCL-1755

...

  • In bridge mode, LAN clients were not getting IP after reboot because erouter0 was not added to brlan0 as EthAgent started late. After the workaround fix, erouter0 was renamed successfully within 1 minute. But working on the actual root cause for this and those changes will be updated in the next release.
