Updated ThreadX version constants and port strings to 6.5.2.202603 (#781)

2026-09-28T18:36:10Z

ThreadX still declares 6.5.1.202602 with hotfix 'a', which is the previous release rather than the one being cut. prepare_release.sh updated the five version constants in tx_api.h and the version string in 211 port headers across ports, ports_smp, ports_arch and ports_module. The hotfix letter is cleared, since the target has none. Nothing else changed: every line in the port commit carries a version, and no file outside an inc/tx_port.h was touched. The port consistency checks passed before the branch was cut, which is what the script gates on. Host regression 113/113 with zero warnings, and the AI disclosure check passes.

Normalized the AI disclosure comment to one fixed line per file (#740)

2026-09-15T21:17:26Z

The per-edit disclosure named the product and model, so every agent and every model version appended another line. 74 files carried two to four of them, and the same five products had accumulated 13 spellings -- Copilot against GitHub Copilot, Claude Sonnet 4.6 against claude-sonnet-4.6, four spellings of Codex. Twenty assembly lines carried a doubled comment marker, `; //` or `@ //`. Every file now carries exactly one line, fixed text naming no product: Portions of this file were generated with AI assistance. It is written with the comment character that file already uses, so the `;` and `@` assembly files keep theirs and the doubled markers are gone. Precise attribution stays on the commit, where the Assisted-by trailer is per-change, dated and attached to the diff it describes. A header line cannot hold that record honestly, because the code it names gets rewritten and the line stays. A file-level flag answers whether; the history answers who. Comment-only. 455 files, 455 insertions and 574 deletions: every removed line was a disclosure line, every added line is the fixed text, and no file is left with zero or with more than one. `scripts/check_ports.sh` passes, including the reproducibility check that would catch a ports_arch master and its generated copies drifting apart. Recompiled against dev, every file that builds without a vendor toolchain gives a byte-identical object: 19 of 19 C files under common, 100 of 100 GNU assembly files, and all 16 assemblable files whose comment marker changed. The 10 remaining marker changes are ac5 and IAR sources where `;` already started the comment and only the redundant `//` was removed. Assisted-by: Claude Code (Opus 5)

Removed the vector table offset register and system stack pointer setup from the Cortex-M low-level initialization (#714)

2026-09-09T20:28:59Z

_tx_initialize_low_level wrote VTOR and derived _tx_thread_system_stack_ptr from the reset vector on every Cortex-M port. Programming VTOR is the job of the low-level startup code that runs before the kernel is entered, and doing it again inside ThreadX silently overrode a vector table that the application, a bootloader or a firmware update had already installed. It also forced every application to export a vector table symbol that the kernel itself never needed. _tx_thread_system_stack_ptr is never read by any Cortex-M port, so the value copied out of the reset vector served no purpose. Both blocks are removed from all Cortex-M ports, together with the now-unused symbol declarations. The GreenHills files keep the NVIC base address load that the removed block used to leave in r0 for the SysTick setup that follows. Applications that relied on ThreadX programming VTOR must now set it in their startup code. The bundled examples link their vector table at address zero and run on the reset default.

Removed generated build output and per-user IDE state, and fixed two stale link lines (#618)

2026-08-15T20:40:19Z

* Removed generated build output and stopped two scripts naming deleted archives Three kinds of file in the tree are produced by a build rather than written by hand, and one pair of scripts still links archives that were deleted years ago. Keil writes ThreadX_Library.plg on every build; the two committed copies are HTML build logs from someone's machine. Code Composer generates the makefiles under ports/c667x/ccs/example_build/tx/Release from the project files beside them, so makefile, objects.mk, sources.mk, subdir_rules.mk, subdir_vars.mk and ccsObjs.opt are all regenerated output. The arm9 and arm11 sample builds link libc.a, libgcc.a and, for arm11, libnosys.a from their own example_build directories. Those archives were removed in 6.1.10 under "Removal of unneeded files", and libnosys.a in #594, but the link lines were never updated, so both examples fail immediately with arm-none-eabi-ld: cannot find libc.a: No such file or directory Link through the compiler driver instead, the shape every other example in the tree uses since #594: the driver supplies libc and libgcc, and SYSCALL_LIB is already defined in both scripts. That does not make either example link, and the fix stops short of that on purpose. With the archives no longer named, both now fail on undefined reference to `_fini' because their linker scripts define the .init and .fini sections but not the _init and _fini symbols, which live in crti.o and crtn.o and are omitted by -nostartfiles. Making those two old cores build is a separate question from removing a stale reference, so they stay in EXAMPLES_EXPECTED_TO_FAIL, with the comment there corrected: it blamed newlib multilib packaging, which is true of cortex_r4 and cortex_r5 but was never the reason for arm9 and arm11. Reproduced throughout with arm-none-eabi-gcc 13.2.1. Assisted-by: Claude Code (Opus 5) * Removed the Keil per-user state files and ignored them Every Keil project in the tree carried a second file holding per-user state: 25 .uvoptx beside the 25 .uvprojx, 9 .uvopt beside the 9 .uvproj, and 3 .uvgui multi-project workspace files. uVision rewrites all of them whenever a project is opened, so they record whoever last had it open rather than anything about the port: debugger selection, breakpoints, watch windows, window geometry. Nothing in the tree references them, and every affected directory keeps its .uvprojx or .uvproj, which is the file that actually describes the project. Add ignore rules so they do not come back the next time someone opens a project and commits. 1.4 MB across 37 files. Assisted-by: Claude Code (Opus 5)
