I. Kernel and Version Updates
1.1 XuanTie C908 BSP merged: QEMU virt64 platform supports RT-Thread Smart
Date: 2026-08-28 (merged 12:25 Beijing Time) Source: RT-Thread/rt-thread PR #11719
The most significant merge into the main repository within the window: feat[bsp][xuantie]: c908 support rt-smart. Submitted on behalf of the author by BadmintonMaster (original commit from shuta.lst’s rt-thread fork), merged by core maintainer Rbb666 on 08-28 12:25 (UTC 04:25), spanning 27 files. Contents: a new bsp/xuantie/virt64/c908 board support package — a port of the T-Head XuanTie C908 processor based on the QEMU RISC-V64 VIRT virtual platform, supporting both RT-Thread Smart microkernel mode (kernel/user-space separation) and standard mode builds, accompanied by root filesystem run instructions (link_smart.lds, run.sh); modifications were also made to libcpu/risc-v/common64/mmu.c for SMP adaptation. The toolchain uses Xuantie-900 GCC (musl version, riscv64-unknown-linux-musl- prefix) + Xuantie QEMU emulator. This is the addition of C908 support to the xuantie virt64 BSP family following C910 and others, providing a QEMU virtualization entry point for development and validation of RISC-V vector-extension cores in RT-Thread Smart high-end application scenarios, and represents continued reinforcement of SMP/MMU adaptation in the libcpu RISC-V common layer.
1.2 qemu-vexpress-a9 backtrace support for function names
Date: 2026-08-28 (merged 11:29 Beijing Time) Source: RT-Thread/rt-thread commit 0ae80cc7
Submitted by community developer Hui Su: when RT_BACKTRACE_FUNCTION_NAME is enabled, the Cortex-A9 QEMU BSP passes -mpoke-function-name to the compiler and assembler, so that kernel backtrace output carries function names for easier debugging. The change is confined to a single file, bsp/qemu-vexpress-a9/SConstruct, and is a minor debugging-experience improvement.
II. Official and Community Activities
2.1 Livestream preview: From ADC to DMA, how to design a data acquisition component?
Date: 2026-08-28 (published) Source: EET China (original eet-china.com/mp/a520847.html)
| EET China published an RT-Thread livestream preview on 08-28 titled “From ADC to DMA, how to design a data acquisition component?” Topic outline: first, why ADC is not equivalent to data acquisition; second, how to choose between periodic sampling and DMA sampling paths; third, multi-channel interleaved frames — how to organize data to balance throughput and real-time performance. This livestream is a continuation of the earlier article “Ruiqing Platform | Design and Practice of RK3506 Multi-Channel Data Acquisition Component” (eet-china.com/mp/a520342), with the same topic series moving from engineering practice to livestream teaching, corresponding to the Ruiqing industrial platform’s capability output in the industrial control data acquisition direction. The original site was unreachable via direct connection from this machine; details are based on search index summaries and titles. |
2.2 Official news API sees no new entries for the ninth consecutive day; Ruiqing Workshop post-event coverage still absent
Date: 2026-08-29 Source: RT-Thread official news API
The official news API (rt_org category) still shows 5 old entries, the latest being the 2026-06-17 Abu Dhabi Investment Forum report, with no new entries for the ninth consecutive day; the news / activity category endpoints continue to return “category data does not exist.” The “Ruiqing Industrial Platform Workshop” (held in Shanghai on 08-27) post-event coverage that yesterday’s report flagged for verification still has not appeared within the window: gnews “睿擎 when:3d” returned 10 hits, all word-splitting noise from Ford Lingrui, Boyue L i-HEV, Geely Emgrand Smart Engine, etc.; the exact query “睿擎派” returned only 1 result, also a Lingrui video. The official news front remains quiet, with only one media-side item — the EET China livestream preview. Ruiqing Workshop follow-up coverage remains a watch point for tomorrow.
III. Ecosystem and Vendor Adaptation
3.1 canopennode-rtt continues iterating: SRDO object dictionary and build/test improvements
Date: 2026-08-29 (committed 11:10 Beijing Time) Source: wdfk-prog/canopennode-rtt
The CANopenNode integration software package for RT-Thread (maintained by community developer wdfk-prog) added 3 commits within the window: canopen[srdo] generating J09/B09S object dictionaries (SRDO, Safety-Relevant Data Objects), a new MCU diagnostic test fixture, and cumulative Phase B build configuration (CI). The package has been iterating on LSS (node configuration) persistence and runtime bitrate activation since 08-25, was first covered in this briefing on 08-27 (LSS runtime bitrate activation), and today continues advancing toward CANopen safety extensions (SRDO) and engineering practices (CI/testing). CANopenNode is a well-known open-source CANopen protocol stack; this package is a personal project (1 star), has not yet entered the RT-Thread packages index, and is noted as an ecosystem reference.
IV. Industry Applications
No new industry application entries within the window. Recent three-day trends: on 08-27, EET China published a Malaysia smart-city IoT customer success story (flood warning + air pollution monitoring, already covered in the 08-28 briefing); the Ruiqing Industrial Platform Workshop was held in Shanghai on 08-27, with post-event coverage still absent; within this window, the industry side shows the Ruiqing platform’s data acquisition livestream teaching as a continuing signal.
V. Summary and Trend Observations
- XuanTie C908 fills in the RT-Thread Smart virtualization validation entry point: The QEMU virt64 platform adds a C908 BSP, supporting RT-Thread Smart microkernel and root filesystem operation, accompanied by SMP/MMU adaptation changes in the libcpu RISC-V common layer — the RISC-V application processor direction (rt-smart) advances further in T-Head core coverage, and this is the most valuable main-repository merge within the window.
- Official news front quiet for the ninth day: No new entries in the news API, and Ruiqing Workshop post-event coverage remains absent; the only media-side item is the EET China “ADC to DMA data acquisition” livestream preview.
- Ruiqing platform content output shifts toward livestream teaching: Following the RK3506 multi-channel data acquisition engineering practice (published around 08-22), the official team is running a livestream series on ADC/DMA data acquisition component design; the industrial control data acquisition direction is currently one of the main external threads of the Ruiqing ecosystem.
- Community CANopen safety capabilities grow slowly: canopennode-rtt moves from LSS configuration toward SRDO safety object dictionaries and CI/test improvements; the CANopen industrial bus ecosystem continues to accumulate on the RT-Thread side in the form of personal projects.
- Only 2 merges into the main repository within the window: C908 rt-smart (new BSP) + qemu-vexpress-a9 backtrace improvement; overall this is a feature lull period, consistent with yesterday’s Renesas BSP wrap-up pace.
Limitations: The EET China original site (eet-china.com) timed out via direct connection from this machine; livestream preview details are based only on search index summaries and titles; Ruiqing Workshop post-event coverage may have been published only on official WeChat channels, which gnews word-splitting noise cannot cover; canopennode-rtt is a 1-star personal project with limited influence, included only for ecosystem observation.
