I. Kernel and Version Updates

1.1 NXP FRDM-MCXC162 board BSP merged into main repo, landed three days after review (PR #11785)

Date: 2026-09-08 (merged at 16:15 Beijing time, i.e., 08:15:21Z)　Source: RT-Thread/rt-thread commits (PR #11785)

PR #11785 [bsp][nxp] Add FRDM-MCXC162 BSP support (submitted by yandld), which was listed in yesterday’s report as pending review, was officially merged into master this afternoon. The PR was created on the evening of 09-07 (still under review when included yesterday, with updates as late as this morning), and completed review and merge in just three days — a relatively fast pace. FRDM-MCXC162 is an entry-level development board in NXP’s MCX C1xx series, and the BSP covers standard peripheral adaptation within the MCUXpresso ecosystem. yandld is a long-time contributor to NXP BSPs and has submitted BSPs for several NXP boards this month; this merge, together with their concentrated cleanup of older NXP BSP PRs on the morning of 09-08 (covered in yesterday’s 1.3), forms a queue-tidying loop of “new boards in, old tickets cleared.” The release remains v5.2.2 (2025-10-31), with no new version release activity.

1.2 Two more merges into the main repo: Keil include path order preservation (#11741) and Renesas GPT PWM register reads (#11753)

Date: 2026-09-08 ~ 2026-09-09　Source: RT-Thread/rt-thread commits (commit 66648255, commit d7ea2bce)

Two additional merges landed in the main repo during the window:

  • [tools][keil] Preserve include path order (merged 09-08 17:03 Beijing time, PR #11741): fixes the issue where include path order was altered during Keil project generation, ensuring path priority behaves as expected. The PR was created on 08-24 and merged after roughly two weeks of review; it is a toolchain (Keil MDK project generation) robustness fix, in line with the recent cadence of “steady digestion of the review queue” alongside yesterday’s merged sal overflow fix and AT hostname out-of-bounds fix.
  • [bsp/renesas][drivers] Read PWM settings from GPT registers (merged 09-09 10:33 Beijing time, PR #11753, commit d7ea2bce): a change to the Renesas HAL driver layer drv_pwm.c (+94/-22), switching to reading the current PWM configuration (period, duty cycle, etc.) directly from GPT timer registers, keeping driver state consistent with the actual hardware configuration and avoiding desynchronization between software caches and registers. This is another iteration of Renesas RZ/RA series BSP drivers this month — on 08-27 there were two merges covering a Renesas SPI runtime configuration fix and SDHI card detection triggering (both covered). Continuous polishing of Renesas BSP drivers is one of the current main lines of vendor adaptation. This merge sits at the end of the window (10:33 this morning) and is the latest landing action.

1.3 Four new PRs opened: Eclipse hidden directory exclusion and QEMU documentation fixes dominate; ch32 driver framework adaptation PR closed same day without merge

Date: 2026-09-08 (15:11 ~ 22:11 Beijing time)　Source: RT-Thread/rt-thread pulls

Four new PRs were opened during the window:

  • #11787 fix[tools][eclipse]: handle hidden directories in source exclusion (wdfk-prog, created 15:11): fixes handling of hidden directories (dot-prefixed directories) in source file exclusion logic during Eclipse project generation. This week wdfk-prog is also submitting to the official CAN framework refactor (#11779, still open) and the toolchain direction, continuing dual-track contributions of “external ecosystem + official framework” (their canopennode-rtt also saw three commits today, see 3.1).
  • #11788 bsp/wch: ch32_drivers adapt to the RT-Thread 5.3.0 device driver framework (Leeee-wx, created 21:38, closed 22:27, not merged): a PR adapting the WCH CH32 series driver library to the 5.3.0 device driver framework; it was closed without merge about 50 minutes after creation, judged to be a self-withdrawal or a duplicate of an existing approach, with no substantive changes entering the main repo.
  • #11789 [docs] fix outdated and missing apt packages in QEMU Linux quick start (shiptux, created 22:05): corrects outdated/missing apt packages in the QEMU Linux quick start documentation.
  • #11790 [docs] do not tell users to delete /usr/bin/python3 (shiptux, created 22:11): documentation no longer advises users to delete the system /usr/bin/python3 — a correction to avoid the risk of breaking the system Python environment.

#11789/#11790 are documentation quality fixes from the same contributor (shiptux), aimed at improving the timeliness and safety of QEMU virtualization and quick start documentation. On the review queue: #11775 (C908 rt-smart/MMU), #11779 (CAN refactor), and #11772 (heap ASan) saw no new commits during the window and remain open pending review.

1.4 Env (Windows) v2.1.0 GitHub Release object lands, closing the version release loop

Date: 2026-09-08 (11:20 Beijing time, i.e., 03:20:45Z, Release “Release 2.1.0”)　Source: RT-Thread/env-windows releases

When yesterday’s report covered the env-windows v2.1.0 version commit, it noted that “the GitHub Releases page has not yet created a release object, indicating it is pending release” — that Release object was created yesterday at 11:20 (two minutes after the report window cutoff of 11:18), with both the tag v2.1.0 (created 03:04Z) and the Release “Release 2.1.0” (created 03:20:45Z) now in place, fully closing the version release loop. This is a supplementary record of a window-boundary event: as of this report, the latest official release of env-windows is v2.1.0 (2026-09-08), the first version jump for the env-windows repo since v2.0.0 in 2024-07, with official release notes now live alongside the Release.

II. Official and Community Activities

2.1 elexcon 2026 Shenzhen opens today; RT-Thread exhibits with “AI Hardware Full Stack”

Date: 2026-09-09 (opening day)　Source: elexcon 2026 Shenzhen International Electronics Show & Embedded Expo (official channel preview on 08-30, already recorded)

elexcon 2026 Shenzhen International Electronics Show & Embedded Expo opens today (09-09 to 09-11) at the Shenzhen World Exhibition & Convention Center (Bao’an New Hall), with RT-Thread exhibiting (booth updates previously recorded in the 08-30 report). The countdown to the debut of the “Gino Pi flagship maker platform” previously teased on the official WeChat account (added yesterday) coincides with the show period; whether it will be unveiled as a booth debut remains to be verified by on-site information today. As of the generation of this report (morning of the opening day), there is no media coverage from the show floor (gnews elexcon-related queries returned 0 hits, a normal lag for the morning of the opening day). Official external content is expected to be released in a concentrated manner over the course of the show; tomorrow’s report will follow up on day-one developments.

2.2 2026 Shanghai Open Source Software Application Innovation Competition: RT-Thread livestreams at 17:00 today to explain the AI quality inspection challenge

Date: 2026-09-08 (multi-platform preview) to 2026-09-09 (livestream in progress)　Source: OSChina “RT-Thread Expert Explains: Clarifying the Last Mile of AI Industrial Quality Inspection Deployment”, CSDN techforward

RT-Thread’s challenge in the “2026 Shanghai Open Source Software Application Innovation Competition” (hosted by OSChina, implementing the “Shanghai Strengthening Open Source…” policy, under the theme “Open Source Toward Practice,” with three tracks: AI + Industrial Software / Intelligent Computing Cloud / Open Source AI Tools) has entered the livestream explanation stage: at 17:00 today, Guo Zhanxin, Solution Lead of RT-Thread’s Industrial Business Unit, will appear in the “OSC Open Source Community” video channel livestream to explain the challenge on site, covering the background of the problem statement and the bottlenecks in the “last mile” of AI quality inspection deployment. The challenge is “Lightweight Adaptation and Low-Code Deployment Optimization of Pre-trained Vision Models Based on the Ruiqing Industrial Development Platform,” announced on 09-03 and recorded yesterday: the foundation is the Ruiqing Industrial Development Platform (high-real-time industrial kernel + NCNN inference framework, with native support for YOLOv3 general object detection), requiring the completion of a four-stage toolchain covering data collection and normalization, online annotation of defect samples, custom model quantization and operator adaptation, and one-click low-code deployment, without modifying the platform’s real-time kernel. Competition registration closes on October 11, with the finals held in Shanghai on October 24; winning projects will share a prize pool of 1 million yuan (cash, Tokens, large model APIs, etc.) and have the opportunity to be selected for Shanghai’s open source project cultivation program. This is RT-Thread’s second key milestone in leveraging a regional open source competition to advance the Ruiqing industrial platform ecosystem and developer recruitment (problem statement release → challenge livestream explanation → registration deadline → finals), forming a two-track external push this week alongside the opening of elexcon 2026 today.

2.3 Official news API sees no new entries for the 20th consecutive day

Date: 2026-09-09　Source: RT-Thread Official News API

The official news API (rt_org category) still shows 5 old entries, the latest still being the 2026-06-17 Abu Dhabi Investment Forum report, with no new entries for the 20th consecutive day. Recent substantive updates to the official website’s news channel have all gone through WeChat account / third-party platform channels (such as the previews and livestream in 2.1 and 2.2), while the official website news section itself has been silent for 20 days. Today is the opening day of elexcon 2026; if show information is released in the form of official website news, it will be a signal of the end of this API’s silence.

III. Ecosystem and Vendor Adaptation

3.1 canopennode-rtt merges three CiA401 features within the window: RT-Thread device profile support, logical devices in multi-device nodes, MSH test controls

Date: 2026-09-08 (batch merged at 17:56 Beijing time, i.e. 09:56:22Z)　Source: wdfk-prog/canopennode-rtt commits

The external ecosystem repository canopennode-rtt (a CANopen port maintained by wdfk-prog) batch-merged three new feature commits within the window (author dates 09-07 to the morning of 09-08, uniformly merged on the evening of 09-08):

  • feat[canopennode][cia401]: add RT-Thread device profile support: CiA401 (I/O device profile) gains an RT-Thread-oriented device profile support layer;
  • feat[CiA401][device]: support logical devices in multiple-device nodes: logical device support in multi-device node scenarios (multiple logical devices under a single node);
  • feat[CIA401][RTT]: add MSH bench controls for device testing: new MSH command-line bench controls to facilitate device testing.

This is the second batch of CiA401 features following the two commits on 09-06 covering CiA401 analog events and fail-safe implementation (already covered), marking the migration of the CANopen CiA401 device profile on the RT-Thread side advancing from the “protocol frame level” to the “device profile + multiple logical devices + test toolchain” level, with the feature surface continuing to expand. wdfk-prog is simultaneously pushing a CAN driver lifecycle refactor (#11779) in the official repository; the dual track of “external ecosystem porting + official framework” makes him the most active contributor in the RT-Thread CAN/CANopen space today.

3.2 Two updates to the packages index: Tencent IoT SDK configuration adjustments, autogen_parameter_manager config option refactor

Date: 2026-09-08 (17:56 / 18:16 Beijing time)　Source: RT-Thread/packages commits (5d983b53, 866a20b5)

The packages software package index repository broke its silence since 09-01 (a full week with no commits after the CANopenNode index was added), with two new commits within the window:

  • Update Tencent IoT SDK package configuration (#2034): Kconfig and package.json configuration updates for the Tencent Cloud IoT SDK package (iot/iot_cloud/tencent-iot-sdk), a routine configuration follow-up for a cloud platform SDK package;
  • refactor(autogen_parameter_manager): adjust Kconfig configuration option defaults: the misc/autogen_parameter_manager package removes forced dependency selections on RT_USING_HEAP and RT_USING_CAN, and changes the defaults of AUTOGEN_PM_USING_NVM and AUTOGEN_PM_NVM_OBJECT from y to n — lowering the barrier to adopting the package so that the power management parameter generator can be optionally installed in configurations without a heap or CAN. This refactor direction is consistent with the recent “remove dependencies, add flexibility” adjustments across multiple packages (compare with the pace of new index additions such as CANopenNode on 09-01).

3.3 Ecosystem verification: awtk push is a general GUI improvement, not RT-Thread-specific, excluded

Date: 2026-09-09　Source: zlgopen/awtk commits

The fetch window hit zlgopen/awtk (pushed at 09-09 00:23Z); verification of the commit contents shows general AWTK framework GUI changes such as combo_box interaction improvements, duplicate bsearch code cleanup, and emitter_dispatch_log optimization, with no direct relevance to RT-Thread-specific work (consistent with yesterday’s verification conclusion for a push from the same repository), so it is excluded. The topic:rt-thread ecosystem repositories saw only this one new push in the past 7 days, with ecosystem repositories remaining low in activity.

IV. Industry Applications

No new deployment case reports. There was no news of new industry applications/deployment cases within the window; the most substantive industry-side action is the live-streamed interpretation of the AI industrial quality inspection challenge at 17:00 today by RealSiDe’s Industrial Business Unit as described in 2.2 — the RuiQing industrial platform (industrial kernel + NCNN + YOLOv3) addressing the toolchain gap for the “last mile of AI quality inspection” represents RealSiDe’s systematic layout in the industrial quality inspection direction from product to developer ecosystem, and the outstanding adaptation solutions produced by its finals (10-24, Shanghai) may feed back into platform capabilities. On-site developments at elexcon 2026 (industrial/robotics/automotive electronics segments, opening today) form the next industry content window, to be followed up tomorrow.

V. Summary and Trend Observations

  • Kernel side: 3 merges to the main repository within the window — the NXP FRDM-MCXC162 new board BSP (#11785, merged three days after review, listed in yesterday’s queue and landed today), Keil include path order preservation (#11741), and Renesas GPT PWM register read (#11753, merged at 10:33 this morning as the latest action in the window); the 4 newly opened PRs are concentrated on toolchain (Eclipse hidden directories) and documentation (QEMU quick start, python3 removal suggestion) fixes, while the ch32 driver framework adaptation PR was closed without merging the same day; the review queue #11775/#11779/#11772 remains open and being processed. The vendor BSP adaptation mainline (new NXP board + Renesas driver polishing) continues yesterday’s trend.
  • Ecosystem side: canopennode-rtt batch-merged three CiA401 features within the window (RT-Thread device profile support, logical devices in multi-device nodes, MSH test controls), advancing the CANopen CiA401 port to the device profile layer; the packages index updated for the first time in a week (Tencent IoT SDK configuration, autogen_parameter_manager dependency-removal refactor); the awtk push was verified as general GUI improvements and excluded.
  • Official/events side: elexcon 2026 opened today (09-09) in Shenzhen, with RealSiDe exhibiting; whether the “Gino Pi” new product makes its booth debut remains to be verified; RealSiDe’s AI quality inspection challenge live interpretation is at 17:00 tonight (OSC Open Source Community video channel, presented by Guo Zhanxin), and the 2026 Shanghai Open Source Software Application Innovation Competition has entered its registration promotion period (deadline 10-11, RMB 1 million prize pool); the official news API has been silent for the 20th consecutive day.
  • Trend over the past three days (09-07 to 09-09): 4 PR batches merged into the main repository + new PRs #11785/#11782 + env-windows v2.1.0 release (09-07 to the morning of 09-08) → sal overflow fix merged, old NXP PR cleanup, OSPP RISC-V topic proposal (early 09-08) → FRDM-MCXC162 BSP merged, three canopennode-rtt CiA401 merges, dual packages updates, env-windows Release landed, elexcon opening + AI quality inspection challenge livestream (09-08 to 09-09). The mainline of progress is “normalized main repository review/merging (BSP expansion + toolchain fixes) + CANopen CiA401 ecosystem expansion + dual external event tracks (elexcon exhibition + open source competition livestream)”.
