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 developer machine paths from the shipped project files (#603)

2026-08-11T23:39:41Z

The Arm Development Studio launch configurations and the IAR project files carried absolute paths from the machines they were last opened on: four individuals' home directories, a Broadcom support build tree, and directories such as C:\release\threadx, C:\temp1702\tx and D:\threadx. They are published in the repository and none of them resolves for anyone else. In the launch files all of it is saved session state, which files that were never opened in a debugger simply do not have: breakpoints 72 files, saved breakpoints anchored to source paths under cortex_a35 on one machine. Emptied rather than deleted, matching the 27 launch files that already carry an empty list. scripts_view_script_links 70 files, a scripts view cache. The script the launch actually runs is named one line earlier through ${workspace_loc:...}, which is portable. substitutePath 65 files, source lookup remapping. 30 map a path to itself, and the rest point at one machine's copy of libgloss or a build directory. TREE_NODE_PROPERTIES 39 files, which rows the variables view had expanded. DebugCommandLine.History 2 files, the debug console command history, including a typed absolute path. The two IAR cases are not session state and are corrected rather than removed: IarchiveOutput 23 files. The librarian output path pointed at another machine, so the library was written outside the project. Set to ###Unitialized###, which 86 other option blocks already use, letting IAR derive $EXE_DIR$\$PROJ_FNAME$.a. IlinkIcfFile 1 file. The linker configuration file is load bearing, so the file name is kept and the path made project relative, as 33 other option blocks spell it. Seven of the files are ports_arch templates, so the generators would otherwise have copied the paths back. Verified: all 162 launch and IAR project files in the tree parse as well-formed XML afterwards, no tracked launch or project file mentions any of the four user names, and scripts/check_ports.sh passes, so the templates and their generated copies still agree.

Add SysTick counter reset in Cortex-M ports (#561)

2026-06-24T16:16:51Z

* Add SysTick counter reset in Cortex-M ports The SysTick counter value (SYST_CVR @0xE000E018) is indeterminate after reset. Without clearing it prior to enabling the counter, the first tick interval becomes unpredictable. * Fixed missing comment and added generated-by header in Cortex-M0/AC6 port Added the missing inline comment on the LDR r1, =0 instruction (Build value for SysTick reset) and the required AI-generated attribution comment under the copyright header. --------- Co-authored-by: Frédéric Desbiens Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

Added copyright headers to files missing them

Applied the standard MIT license header to all project-owned C, header, assembly, shell, and Python files that were missing a copyright notice. Third-party, toolchain startup, and auto-generated files were excluded. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

Updated copyright headers and version number constants (#509)
