I. Kernel and Version Updates

1.1 STM32 SPI BDMA support merged into mainline, DMA / BDMA / GPDMA configuration unified (PR #11689) (09-14)

Date: 2026-09-14 09:59 (Beijing time, merge time; author submission date 09-11)　Source: PR #11689

Mainline resumed merges after the v5.3.1 version bump, and the first functional commit in this window is BDMA support for STM32 platform SPI, which also unifies the configuration approach for the three transfer channel types DMA, BDMA, and GPDMA (with an accompanying clang-format formatting commit). BDMA is an independent DMA controller available in the low-power domain on STM32H7 / U5 and other series; previously the SPI driver only used the general-purpose DMA path. This merge completes SPI transmit/receive capability on BDMA channels, offering direct value for industrial and sensor scenarios that need to maintain peripheral transfers in STOP low-power mode. The PR took several days from opening to merge and is a community-driven peripheral driver enhancement.

1.2 Two QEMU getting-started documentation fixes merged (PR #11789 / #11794) (09-11)

Date: 2026-09-11 13:23 and 13:26 (Beijing time)　Source: PR #11789, PR #11794

Two documentation fixes were merged on the same day: one adds the missing apt dependency packages in the QEMU Linux quick-start process, and the other updates the no-longer-valid GNU GCC toolchain download link in the qemu-vexpress-a9 README. The author dates of the two commits are 09-07 and 09-08 respectively, making these wrap-up merges after a long period of being stalled. The QEMU emulator is the most common hardware-free getting-started path for RT-Thread, and documentation usability directly affects new developers’ first experience.

1.3 Four security-related issues closed together on 09-13 (tmpfs / message queue / pread / finsh completion) (09-13)

Date: submitted 2026-08-23, closed together 2026-09-13 15:46 ~ 15:47　Source: #11735, #11736, #11737, #11738

Four security defects submitted on the same day were marked as completed and closed together on 09-13, covering: a stack buffer overflow in tmpfs path handling (_path_separate / _get_subdir) caused by long path components, an unbounded stack overflow in mq_unlink() and an off-by-one error in mq_open() in POSIX message queue name handling, an out-of-bounds heap read in tmpfs (information disclosure or crash) caused by pread() passing a large negative offset that bypasses rw_verify_area(), and a heap out-of-bounds write in finsh TAB auto-completion (msh_auto_complete_path) caused by completion results not being trimmed to the line buffer. All four were claimed and closed by the same submitter, and no fix commits corresponding one-to-one with them are visible in public comments or commit history; the actual path by which the fixes landed (possibly folded into the v5.3.0 dfs / posix hardening batch, or handled through a separate internal process) still needs verification. For industrial and automotive scenarios that tout RT-Smart along with file system and message queue capabilities, the closure progress of this batch of defects is worth continued tracking.

1.4 Review queue watch (1): New BSPs and domestic MCU driver extensions submitted intensively (09-14)

Date: 2026-09-11 ~ 2026-09-14　Source: #11799, #11800, #11798, #11764

Newly opened and updated BSP / driver PRs in the window are concentrated: the stm32n657-st-nucleo BSP for STMicroelectronics’ STM32N657 series (84 files, +15340 lines), the Nations Technology N32H series drivers expanded from a single board to three boards n32h487zgl7-evb / n32h497zgl7-evb / n32h760zil7-stb (69 files, +7561/-2754 lines, covering ADC, DAC, Ethernet, I2C, SPI, QSPI, NAND, SDRAM, etc.), the Xiaohua Semiconductor HC32 series driver extension, and CherryUSB component support for N32H4x USBFS device side. Overall this shows a pattern of “domestic MCU vendors and ecosystem developers intensively filling in BSPs,” consistent with the adaptation window after a new version release.

1.5 Review queue watch (2): lwip 2.2.1 stack support enters the queue, toolchain and USB fixes coexist (09-14)

Date: 2026-09-11 ~ 2026-09-14　Source: #11797, #11743, #11770, #11748

Component and tool updates in the review queue: newly added lwip 2.2.1 stack support (1875 files changed, fixes #11588, validation platform is NXP i.MX RT1180 EVK, configuration RT_USING_SAL + RT_USING_NETDEV + RT_USING_LWIP), which will advance the mainline network stack from the existing lwip 2.1.x baseline to 2.2.x; on the tool side there is an improvement to “automatically select Keil / IAR target based on Kconfig linker script”; on the defect fix side there is a correction of the type alias conflict between rt_ringbuffer and rt_serial_rx_fifo in USB VCOM, as well as a newly added kernel configuration option for stack pointer alignment.

1.6 Review queue watch (3): QEMU rt-smart support for DAMO XuanTie C908 continues to advance (09-14)

Date: opened 2026-08-31, updated 2026-09-14 10:16　Source: PR #11775

Adds rt-smart support for the QEMU emulation platform (xiaohui c908) targeting DAMO XuanTie C908, including MMU sv39 / sv48 page table modes and SMP multi-core boot, and supplements mmu_dem related capabilities, with 31 files changed, +2575/-565 lines. The PR is still under review. For the RISC-V side, this is a key step toward emulator-level validation of RT-Thread Smart (the hybrid deployment form with MMU) on XuanTie’s energy-efficient cores, and can be used to validate process isolation and user-space applications without hardware.

1.7 New defect report: SDIO driver deregistration failure and node memory leak risk (#11801) (09-12)

Date: 2026-09-12 14:56 (Beijing time)　Source: #11801

One new driver-related defect report in the window: the SDIO driver has a risk of failure and node memory leak on the deregistration path, and has been tagged bug and component: drivers, with no one having claimed it yet. SDIO is the shared bus for Wi-Fi modules and storage cards, and this issue has potential impact on hot-plug and resource reclamation scenarios for long-running devices.

II. Official and Community Activities

2.1 RT-Thread Releases August Community Monthly Review: Malaysia University Collaboration and Southeast Asia Workshops as Highlights (09-12)

Date: 2026-09-12 11:50 (Beijing Time, industry media repost time)　Source: EE Times China (Google News aggregated entry) (original link: eet-china.com/mp/a524394.html)

RT-Thread released its August community monthly review. According to its public summary, August’s main external activities centered on universities and the overseas ecosystem: on August 1, it traveled to Malaysia to sign a Memorandum of Understanding (MoU) with Wawasan Open University, kicking off the collaboration with an “RT-Thread × Infineon Edgi-Talk Workshop” that drew 47 attendees (mostly professors and engineers), with on-site booths featuring a virtualized hybrid-deployment demo car and Edgi-Talk, among others; during the same period, it visited Universiti Sains Malaysia (USM), Universiti Malaya (UM), Universiti Tenaga Nasional (UNITEN), Xiamen University Malaysia (XMUM), UCSI University, and other institutions to discuss curriculum co-development, application projects, and joint laboratory directions. Combined with information from official English channels, its total university collaborations have approached 200, and on the Southeast Asia side, since 2025 it has continued to run workshops in Thailand with Thammasat University, Mahidol University, King Mongkut’s University of Technology Thonburi, Rajamangala University of Technology Thanyaburi, and the Royal Society of Thailand, among other institutions. The monthly review is routine official community operations material and can serve as a gauge for observing the pace of its education and talent ecosystem expansion.

2.2 Official News API Sees No New Entries for the Twenty-Fifth Consecutive Day (09-14)

Date: 2026-09-14　Source: RT-Thread official news API (type=rt_org)

The official news API homepage still shows the entry dated 2026-06-17 as the latest, marking the twenty-fifth consecutive day with no new additions. Compared with the previous cadence, official external news releases have entered a prolonged silent period, with public information increments mainly coming from GitHub commits, developer community articles, and industry media reposts.

2.3 Four New Community Forum Articles: Lely CANopen Master Selection, probe-rs Debugging, Motion-Sensing Mouse, C Runtime Startup Flow (09-11 ~ 09-14)

Date: 2026-09-11 16:32 ~ 2026-09-14 09:59　Source: Community article

Four technical articles were added or updated on the official community forum within the window: first, “lely-canopen-rtt: Why We Recommend Building a Master with Lely CANopen on RT-Thread” (09-11 16:39), introducing the approach of using Lely CANopen in the master role on RT-Thread, corroborating the package index trends in this issue; second, “MCU probe-rs Flashing and Simulation Debugging” (09-11 16:32), filling in usage of the Rust toolchain probe-rs for MCU flashing and online debugging; third, “Building an STM32F407 Spark Motion-Sensing Mouse from Scratch: RT-Thread, ICM20608, USB HID, and LVGL in Practice” (09-12 19:03); fourth, “MCU C Runtime Library Startup Flow” (09-14 09:59). The content focuses mainly on MCU hands-on practice and toolchain primers, continuing the output cadence of the RSOC26 (RT-Thread Spark One) tutorial series.

2.4 Livestream Preview: Hands-On Temperature and Humidity Acquisition from RS485 to Modbus (09-11)

Date: 2026-09-11 11:50 (Beijing Time)　Source: EE Times China (Google News aggregated entry)

RT-Thread released a livestream preview on the theme of connecting the temperature and humidity acquisition chain from the RS485 physical layer through the Modbus protocol stack, scheduled for next week. Such livestreams are standing content operations in the industrial data acquisition direction, consistent with Ruiching industrial platform’s promotion path targeting industrial control R&D.

III. Ecosystem and Vendor Adaptation

3.1 Gino Pi Dev Board Enters RT-Thread Studio SDK Index: GD32H77D-Gino BSP v1.0.0 Released (09-11)

Date: 2026-09-11 12:34 (Beijing Time)　Source: SDK index repo (BSP repo)

The RT-Thread Studio SDK index repo added an “add gd32-ginopi dev board support” commit: board entry GD32H77D-Gino (vendor listed as RealThread), BSP version v1.0.0, release date 2026-09-11, package size 138 MB, source taken from the v1.0.0 archive of the sdk-bsp-gd32h77d-realthread-ginopi repo; meanwhile the GigaDevice board index list added GD32H77D-GINOPI. The BSP repo was created on 09-02, merged its first version “Add GD32H77D Gino BSP SDK” on 09-09, completed schematics, packaging flow, and DXF drawings on 09-10, and completed index mounting within this window, meaning developers can directly create Gino Pi-based projects in Studio. GD32H77D is GigaDevice’s high-performance MCU series; GigaDevice previously reached a strategic partnership with RT-Thread and is focusing on deepening the GD32H7 product line; Gino Pi has thus moved from a trade-show novelty to a downloadable, deliverable stage, making this the most impactful ecosystem action of this issue.

3.2 Three New Package Index Submissions Pending Review: CanopenNode v1.2.0, Virtual Sensor with MQTT, STM32N657xx FSBL Index (09-11)

Date: 2026-09-11 17:09 ~ 22:33 (Beijing Time)　Source: PR #2039, PR #2040, PR #2041

The package index repo added three pending submissions within the window: first, a new stm32n657xx FSBL package repo index under the hal_sdk directory (09-11 17:09); second, the CanopenNode package upgraded to v1.2.0 (09-11 22:18); third, a new virtual sensor package with MQTT upload support (09-11 22:33). The first follows the submission pace of the STM32N657 Nucleo BSP in the main repo, while the latter two continue to strengthen the two commonly used industrial chains of CANopen and sensor data-to-cloud. In addition, three index submissions already covered in the previous issue, including the Lely CANopen package (PR #2038), were merged and closed at 09-11 21:50.

3.3 Ecosystem Repo: lely-canopen-rtt Companion Package and Main Site Article Land in Sync (09-11 ~ 09-12)

Date: 2026-09-12 13:03 (Beijing Time, repo push)　Source: wdfk-prog/lely-canopen-rtt

Among topic:rt-thread ecosystem repos, lely-canopen-rtt (Lely CANopen integration for RT-Thread, featuring a single-owner EV/IO2 runtime and static object dictionary) had a push within the window. The repo author concurrently submitted CanopenNode-related updates to the official package index and published a main site selection article on the community forum, forming a community contribution sample with three synchronized tracks: “package index + downstream repo + technical article.” Under the same query there was also a third-party project h120d-protocol (reverse-engineering a certain handheld gimbal’s WiFi protocol and implementing it with RT-Thread), a personal interest project noted only for ecosystem observation.

IV. Industry Applications

4.1 No New Deployment Cases Within the Window; Industrial Quality Inspection Contest Topic and Golden Compass Award Application Are Continuations of Existing Actions (09-11 ~ 09-14)

Date: 2026-09-11 ~ 2026-09-14　Source: Gasgoo (Google News aggregated entry) (Golden Compass Award application, already covered 09-11)

No new industry deployment case reports were found within the window in the industrial, automotive, or robotics/embodied intelligence directions. Two existing industry-side actions continue: first, RT-Thread submitted its Cheng Xuan full-vehicle basic software OS for the 2026 8th Golden Compass Award Best Technical Practice Application Award (already covered 09-11, no further progress within the window); second, the 2026 Shanghai Open Source Software Application Innovation Competition’s “AI + Industrial Software Track” continues to solicit entries for the topic “Lightweight Adaptation and Low-Code Deployment Optimization of Pre-Trained Vision Models Based on the Ruiqing Industrial Development Platform,” with registration closing October 11. It should be noted that Electronic Engineering Album re-pushed this topic on 09-11 under the title “Industrial Quality Inspection AI That Every Developer Can Build, RT-Thread Topic Announced,” with content identical to the contest topic announced 09-03 and interpreted in a livestream on 09-09; this is a secondary reprint and is not counted as a new entry in this issue. Industrial quality inspection and industrial data acquisition remain its most active external scenario narratives, while public increments on the deployment case side are relatively sparse.

V. Summary and Trend Observations

5.1 Trends Over the Past Three Days (09-11 ~ 09-14)

  • The mainline returned to a normal merge pace: after the v5.3.0 / v5.3.1 releases, the window was dominated by BSP driver enhancements (STM32 SPI BDMA) and documentation fixes, plus four domestic MCU driver PRs submitted intensively for review, placing it in a post-release adaptation window.
  • Security-related defects saw one concentrated closure: four tmpfs / message queue / pread / finsh completion defects submitted on 08-23 were closed together on 09-13, but the public commit history shows no item-by-item fix records; how the fixes landed still needs verification, and continued tracking is recommended.
  • The most concrete ecosystem action of this issue appeared: the Gino Pi (GD32H77D) BSP v1.0.0 was mounted onto the RT-Thread Studio SDK index, moving from trade-show novelty to a downloadable, deliverable stage, as GigaDevice’s GD32H7 line continues to advance hardware-software co-development.
  • Official external news remained silent (twenty-fifth day), with information increments shifting to GitHub and the developer community; on the community side, a three-track linkage of package index, downstream repo, and technical article formed around CANopen (Lely / CanopenNode).
  • No new deployment cases on the industry side; momentum was maintained mainly by the regional open source competition topic (registration closes 10-11) and the Golden Compass Award application, with industrial quality inspection and industrial data acquisition as the most active scenario narratives.
  • On the RISC-V side, there is one long-term item worth watching: QEMU rt-smart (MMU sv39/48 + SMP) support for DAMO XuanTie C908 is still under review and progressing, representing emulator-level validation of RT-Thread Smart on XuanTie cores.

5.2 Limitations and Deduplication Notes

  • This issue is the Monday routine expanded window (past 3 days), covering Saturday and Sunday; public increments on weekdays were themselves relatively sparse, so entries are mainly GitHub facts supplemented by news.
  • The Electronic Engineering Album original site was unreachable from this machine’s network (HTTP/2 protocol errors and timeouts); its August retrospective monthly report and livestream preview entries were taken from aggregated links and public summaries, and monthly report body details (including workshop attendance, exhibited materials, etc.) were not verified word-for-word against the original; the university visit information in the monthly report cross-checked consistently with official English-channel content.
  • The official news API and the official website news center remain frozen since 2026-06-17, the RT-Thread official commercial site returns 403, and official-voice increments are based on industry media reprints and official English channels.
  • The closure of the four security-related issues came with no public explanation or linked PR; this report only states the fact of “concentrated closure” and does not draw conclusions about the completeness of the fixes.
  • The Chinese-language “RT-Thread” query on Google News still mixed in gambling-related SEO content from sources such as Tiyujia and unrelated low-altitude economy articles, which were removed based on title semantics; the English-language “RT-Thread” query continued to hit Rotten Tomatoes film review-type noise, none of which were counted.
