I. Kernel and Version Updates

1.1 Two Merges into the Main Repository: Infineon PWM Macro Mismatch Fix Closed Out, Nations Technology N32H4x USBFS Device-Side Support Merged (09-21)

Date: 2026-09-21 15:43–15:44 (Beijing time, merge time)　Source: PR #11802, PR #11764

Two proposals were merged into the main repository within the window, both closing out items already in the review queue. The first is the Infineon board-level PWM macro mismatch fix: inconsistent macro definitions left over after channel port renaming were resolved in several places, sharing the same origin as the PSoC6 evaluation board BSP correction covered in the previous issue, and now closed out in the mainline. The second is the merge of CherryUSB component support for the Nations Technology N32H4x series USBFS device side: the proposal had entered the review queue earlier this month and landed after review, adding component-level support for USB device functionality on this chip series. Both are fix and adaptation changes; no new feature-level merges occurred within the window, and the mainline saw no new pushes after Monday morning’s concentrated batch.

1.2 Eight New Items in the Review Queue in a Single Day: N32H Timer Completion, STM32 Ethernet Adaptation, and lwip Macro Controls (09-21 ~ 09-22)

Date: 2026-09-21 16:11 ~ 09-22 03:25 (Beijing time, proposal time)　Source: PR #11812, PR #11819

Within the window, the review queue gained seven proposals and one defect report, a single-day density rarely seen recently. The largest is the timer completion for the Nations Technology N32H series (39 files, roughly 4,000 lines): N32H47x_48x and N32H49x share driver files with H7xx, and previously only the H7xx branch was implemented, leaving clock timers, low-power timers, PWM, and pulse encoders compiling to nothing on the two evaluation boards; this change completes the branches for both series, reads back frequencies according to the real clock tree, and adds full continuous integration coverage, continuing earlier driver expansion work. The remaining proposals cover: ops-layer adaptation and PHY model additions for the new STM32 Ethernet driver, along with a synchronized lowering of the default log level for the adcv2 driver; conversion of portions of the lwip component to macro switches; optimization of system resource allocation for the Renesas RA6W1 BSP; fixes to clock dependencies and build protection in unit test performance cases; a path-matching fix for ESP32-C3 builds under Windows; documentation corrections for the bluepill BSP (LED pin labeling and an empty list item) plus a companion defect report (the quick-start guide lacks the step to regenerate the MDK project, so following the documentation fails to compile). The review queue continues its structure dominated by domestic microcontroller adaptation and build-related patches.

1.3 Official News API Sees No New Items for the Thirty-Third Consecutive Day (09-22)

Date: 2026-09-22 (verification time)　Source: RT-Thread official news API

The latest archived item returned by the official news API is still dated 2026-06-17, with no additions within the window, marking the thirty-third consecutive day without updates; the official website’s news list page continues to return a loading failure state and cannot be read directly. Product release and event information continues to debut via the WeChat official account, the official website store, and forum channels; this issue’s store post update (see 3.2) came from that channel.

II. Official and Community Events

2.1 Second Lin-gang “Scenario Express” Held: RealThread Hosts Closed-Door Requirements Matchmaking Session (09-20 report, belated inclusion)

Date: 2026-09-18 (event) / 2026-09-20 (report)　Source: Jiefang Daily · Shangguan News

The second session of “Lin-gang Sci-Tech City · Scenario Express” — the AI large models and agents entering factories special event — was held in Lin-gang on 09-18, hosted by the Lin-gang Special Area Administration. It adopted a supply-demand matchmaking model of “government builds the stage, chain leaders pose the problems, enterprises solve them,” bringing together benchmark case sharing, chain leader requirement announcements, and startup flash pitch sessions. The event featured four closed-door breakout salons, among them the “RealThread Requirements Closed-Door Matchmaking Session,” a dedicated RT-Thread RealThread session conducting targeted negotiations around its specific requirements and AI technology suppliers; the other three focused respectively on large models and agents entering factories, Zhongwei scenario requirements, and AECC general aviation power requirements. The report was published on 09-20 and was not captured in the previous issue; it is included here belatedly, showing RealThread’s continued participation in Lin-gang’s industrial and intelligent manufacturing ecosystem scenario matchmaking.

2.2 Forum MCU Series Updates with Long-Form Article on GNU Linker Scripts (09-22)

Date: 2026-09-22 08:35 (Beijing time, update time)　Source: Forum article bcc6d010c550766f

Community author “大目熊”’s MCU low-level series updated within the window with a long-form article on GNU linker scripts (previous installments in this series on probe-rs flashing and debugging and the C runtime library startup flow have both been covered). Using an STM32F103 project as an example, the article first explains the section structure in object files (.text/.data/.bss/.rodata) and the linker’s unified consolidation, then explains why address planning under an MCU with no memory management unit must be explicitly arranged by the linker script, and goes on to present how to write a GNU ld script for bare-metal programs, stringing together runtime and load addresses, .data copying, .bss zeroing, and the interrupt vector table into a complete chain, with a companion video on Bilibili. It is a systematic serial, forming a “debug—startup—link” low-level puzzle together with the previous two installments.

III. Ecosystem and Vendor Adaptation

Date: 2026-09-21 11:38 (Beijing time, push time)　Source: Gino Pi BSP SDK repository

The Studio BSP SDK for the Gino Pi (GD32H77D) board pushed three commits within the window, touching 19 files, completing links in bulk around engineering details: first, the SDK manifest gained about 110 lines, adding the J-Link debugger dependency to all example projects, making the J-Link support covered in the previous issue formally effective at the project creation and dependency installation stages; second, the dependency declarations for unit test performance cases were corrected (configuration items and build scripts), fixing their dependency configuration; third, the GCC linker scripts of sixteen example projects were uniformly corrected, preserving unit test-related sections and marking initialization arrays as read-only. This SDK has continued to fill in details across the debugging and testing chain since around the board’s release, and this issue continues that pace.

3.2 Official Website Store Gino Pi Release Post Updated: Purchase Channel and First-Batch Review Campaign Clarified (09-22)

Date: 2026-09-22 07:51 (Beijing time, update time)　Source: Store release post 05086f4d786c7a0b

The Gino Pi release post was updated within the window, filling in the official elements missing when the release news was previously covered (09-15, at which time an aggregated summary was used): the post now provides the official Taobao product link, the method for claiming the 80-yuan launch coupon (joining the “Gino Pi Interest Group”), and previews the first-batch review campaign — first-batch buyers who later complete peripheral tasks can participate in cashback; the board specification table, example project list, SDK repository, and development board documentation center entry points are all listed. The board and SDK information is consistent with previous coverage; this update completes the release operations and community interaction elements.

IV. Industry Applications

4.1 No New Deployment Cases Within the Window; RK3576 Long Post and Electronics Competition Project Are Existing Leads (09-22)

Date: 2026-09-21 ~ 2026-09-22 (verification time)

No new mass-production or commercial deployment cases occurred within the window. The two community leads previously covered — the RK3576 board heterogeneous AMP networking long post (covered 09-21) and the 2026 electronics competition Problem H balancing ball project (covered 09-18) — were both old-post maintenance updates within the window and are not reported again. There were no new developments in robotics or embodied intelligence within the window, consistent with the previous week’s pace.

V. Summary and Trend Observations

5.1 Recent One-Day Trends (09-21 ~ 09-22)

  • Mainline closed out Monday afternoon, activity shifted to the review side: Both merges were closures of existing items; eight new proposals and defects opened in a single day is rare recently, among them the N32H timer completion at nearly 4,000 lines, with the review queue dominated by domestic microcontroller board-level and build-related patches.
  • Gino Pi entered its operations and engineering phase: On the SDK side, J-Link dependencies, linker scripts, and the test framework were filled in; on the release side, the purchase channel and review campaign were added. The board’s focus shifted from “release” to “debuggable and participatory,” continuous with the J-Link and RealThread adaptation work of the previous two issues.
  • Official channels silent for the thirty-third day: Product and event information continues to debut via store, forum, and media channels; this issue’s store post update and the Lin-gang event report both came from non-official-news-API channels.
  • Community and media output steady: The forum MCU low-level series continued updating (the linker script installment); local media coverage of the Lin-gang industry event constituted the media-side increment.

5.2 Limitations and Deduplication Notes

  • The Lin-gang event report (published 09-20) falls within the previous issue’s window but was not captured then; it is included here belatedly with the date noted in the title and body.
  • Deduplication notes: the Gino Pi release (covered 09-15 and 09-17; this issue provides only incremental coverage of the store post update and SDK link completion), the electronics competition Problem H project and the RK3576 AMP long post (covered 09-18 and 09-21; this issue covers old-post updates), and the Industry Expo Workshop and “media perspective” articles (covered 09-20 and 09-19) are all not reported again.
  • The “update time” of store release posts and forum articles refreshes with editorial updates; item dates in this issue follow the update time returned by the API.
  • The official news API and the official website news list page are in the same state as before (thirty-third day without updates, page not directly readable); release post information is based on its body text, with no actual testing of the purchase flow.
