I. Kernel and Version Updates

1.1 WLAN Framework Adds WPA3/Enterprise/WAPI/OWE/DPP Security Mode Flags (Merged August 17)

Date: 2026-08-17 (merged at 11:00 Beijing time; author submitted on August 11, batch merge pattern)　Source: rt-thread main repo commit 0823a4b

The security flag bits in components/drivers/wlan/dev_wlan.h were expanded in one pass to add five categories: WPA3_SECURITY (WPA3), ENTERPRISE_ENABLED (WPA2/WPA3 enterprise authentication), WAPI_ENABLED (China’s national WAPI standard), OWE_ENABLED (Opportunistic Wireless Encryption, password-free encryption on public Wi-Fi), and DPP_ENABLED (Wi-Fi Easy Connect device provisioning protocol). Previously only WPA/WPA2/WEP/TKIP/AES bits existed. This is an API capability expansion at the WLAN device framework layer—drivers can now expose modern Wi-Fi security protocol capabilities to applications, with specific driver adaptation to follow. Authored by Kai (submitted August 11), merged into the main repo today at 11:00 by maintainer Rbb666, a typical batch merge pattern.

1.2 [bsp/raspberry-pi] Adds Raspberry Pi 5 BSP and BCM2712 DMA Support (August 16)

Date: 2026-08-16 19:56 (Beijing time)　Source: rt-thread main repo commit f7258a6

Submitted by GuEe-GUI: Raspberry Pi common drivers reorganized under the device framework (DM); new Raspberry Pi 5 BSP added (with configuration and documentation); BCM2712 and DesignWare AXI DMA controller support merged, distinguishing BCM2712’s DMA32/DMA40 channels by channel mask; AXI DMA enable bits restored after controller reset; support for sharing AXI maximum burst length across DMA channels. Pi 5 (BCM2712) is the first Raspberry Pi series board to land in this BSP, advancing RT-Thread’s support for Raspberry Pi hardware to the current mainstream model.

1.3 [bsp/rockchip] Expands Platform and Peripheral Support (August 16)

Date: 2026-08-16 19:57 (Beijing time)　Source: rt-thread main repo commit d890866

Submitted by the same author on the same day: adds audio, display, Ethernet, PCIe, PHY, SDIO, UFS, hardware crypto, and multimedia accelerator support, with synchronized updates to RK3300 and RK3500 platform configurations and validation applications. The Rockchip platform advances from a basic BSP toward full peripheral coverage, with UFS/PCIe/hardware crypto targeting mid-to-high-end storage and edge gateway scenarios.

1.4 No Change in Version Status

Date: 2026-08-17　Source: rt-thread releases

The latest official release remains v5.2.2 (released 2025-10-31); no new releases or pre-releases appeared within the window.

II. Ecosystem and Toolchain (Today’s Focus)

2.1 smart-build Merges ROS 2 Cross-Compilation Support: rt-smart Connects to the Robotics Middleware Stack (August 17)

Date: 2026-08-17 08:07 (Beijing time)　Source: RT-Thread/smart-build PR #50

PR #50 “Add ROS 2 cross-build and Smart package support,” led by BernardXiong, was merged today at 08:07, touching 100+ files (63 of them in the packages/ros2 directory). Key contents:

  • ament_cmake cross-compilation support: grouped discovery of ROS 2 packages and host tool packages, host dependency scheduling, source patches, and C++ runtime staging;
  • ROS 2 package stack: ROS 2 core packages + host SDK + dependency recipes (CycloneDDS, console-bridge, fmt, libyaml, etc.), with pinned version sources + RT-Smart adaptation patches;
  • QEMU aarch64 transport-layer smoke target: new ros2-transport-smoke app/package attached to boards/qemu-virt-aarch64, enabling validation of the ROS 2 transport layer without hardware;
  • Lightweight ipkg package management: ipkg enabled with BusyBox dpkg/rpm functionality disabled, improving BusyBox mount/rootfs runtime integration;
  • Quality gate: all 150 pytest items pass; kernel-side procfs and system compatibility changes are explicitly noted as to be submitted separately.

Significance: Following the Buildroot package import on August 15, smart-build has achieved its second ecosystem-scale leap within four days, shifting direction from a “general application ecosystem” to a “robotics middleware ecosystem.” ROS 2 is the de facto standard middleware for modern robotics/embodied intelligence; with rt-smart gaining ament build and CycloneDDS support, RT-Thread has formally entered the ranks of ROS 2 embedded target platforms. The QEMU aarch64 smoke target continues the groundwork laid on August 15 with QEMU virt dual-architecture readiness, forming a continuous chain of progress.

III. Official and Community Activities

3.1 No New Additions to Official News API

Date: 2026-08-17　Source: RT-Thread official news API

No new additions within the window of the official news API; the latest entry remains the 2026-06-17 Abu Dhabi investment forum report (lagging by about 2 months). No new verifiable announcements regarding the 2026 university summer camp or the Ruiqing ecosystem within the window.

3.2 August 27 Shanghai Workshop Enters 10-Day Countdown

Date: 2026-08-17　Source: EE Times China (indexed August 15)

The August 27 Shanghai “Ruiqing Industrial Platform Workshop: EtherCAT Real-Time Control and Industrial Solutions in Practice” is 10 days from taking place, with no new verifiable teaser items within the window; official content flowing back afterward will be worth watching (see the dedicated industry applications section).

IV. Dedicated Industry Applications Section (Robotics / Embodied Intelligence / Industrial)

  1. ROS 2 support is a landmark event for the robotics direction: rt-smart + ROS 2 (ament + CycloneDDS + QEMU transport-layer smoke) directly addresses the middleware needs of robotics/embodied intelligence. Previously, the “Dishui Zhihui” Lingang embodied intelligence ecosystem layout and the Edgi-X AI flight controller were ecosystem-side moves; this time it is the toolchain side that truly gets ROS 2 build and transport layer running as an engineering foundation. If the official team subsequently submits the accompanying kernel procfs changes, runtime capabilities will be completed. Official ROS 2 examples and robotics vendor adaptation cases can be expected next.
  2. The industrial EtherCAT mainline is unchanged: the Ruiqing Industrial Platform Workshop is 10 days out, with the 26.08.06 release and 3-core industrial PC pre-sales still generating residual interest; no new commercialization moves within the window.
  3. Industry value of completing Wi-Fi security protocol bits: WPA3/enterprise authentication suits industrial gateways, retail terminals, and other scenarios requiring secure access; WAPI targets the domestic compliance market; OWE/DPP target public network experience. With the framework layer ready, common Wi-Fi drivers (Realtek/ESP, etc.) are awaited to follow up with implementations.

V. Summary and Trend Observations

  1. Toolchain ramps up for a third consecutive day, direction clearly shifting to robotics: 8/15 Buildroot package import → 8/16 ENV plugin concurrency → 8/17 ROS 2 cross-compilation. After this three-hit combo, the rt-smart application ecosystem covers both the “general Linux ecosystem (Buildroot)” and the “robotics middleware ecosystem (ROS 2)” fronts, making clear the official intent to make robotics/embodied intelligence the primary thrust for rt-smart in the second half of the year.
  2. ROS 2 landing strategy is pragmatic and incremental: starting from a QEMU aarch64 smoke target and submitting kernel-side changes separately reduces single-merge risk; follow up on the accompanying kernel procfs submissions and real-device ROS 2 running cases.
  3. Dual-track advancement on the kernel-side BSP: Raspberry Pi 5 (BCM2712) and Rockchip (RK3300/RK3500 peripheral expansion) merged on the same day, expanding DM driver framework coverage across mainstream development board platforms; the inclusion of RPi 5 has direct value for the developer base.
  4. WLAN framework security protocol bits completed: WPA3/OWE/DPP/enterprise/WAPI flags are in place, leaving interfaces ready for driver implementation; watch the follow-up pace of common Wi-Fi drivers.
  5. Version front is stable, official API still lagging, media-side verification limited: v5.2.2 unchanged; the official news API lags by about 2 months with no improvement; in this window Google News (zh/en) was unreachable via proxy due to timeouts (see appendix), making media-side verification incomplete; today’s conclusions are based primarily on GitHub merge facts.
