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.

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.

Fixes #551
`_tx_thread_system_return_inline()` in the Cortex-M `tx_port.h` headers spells
its barriers `dsb 0xF` and `isb 0xF`. A bare hexadecimal operand is a GNU
assembler extension, and IAR rejects it with `operand syntax error`, so the
header cannot be included at all. The block is guarded for GCC, armclang and IAR
together, so every IAR user of an affected port hits it -- four independent
reports on Cortex-M33 and M7 with EWARM 9.50 and 9.70.
Both operands become `sy`, the Arm UAL name for exactly what `0xF` encodes. The
generated instruction is unchanged. Applied to the two `ports_arch` masters and
all 32 copies under `ports`, covering M0, M23, M3, M33, M4, M52, M55, M7 and M85
across ac5, ac6, gnu, iar and keil, plus the `scripts/check_ports.sh` probes that
matched the old spelling.
`check_ports.sh` passes, the copy scripts still reproduce every generated port
byte for byte, and `arm-none-eabi-gcc -O2` compiles a caller for every patched
header, emitting `dsb sy` and `isb sy`. Three headers that need toolchain
intrinsics GCC does not ship fail identically on `dev`.

the Cortex-M low-level initialization (#714)
_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.

link lines (#618)
* 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.

* 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.

* 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.

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.

* Fixed race condition and message loss in Cortex-M GNU, AC6, and IAR ports (#516)
- Added compiler memory barriers to BASEPRI management functions in tx_port.h.
- Added architectural barriers (DSB/ISB) to scheduler return paths in tx_port.h and tx_thread_system_return.S to prevent fall-through before context switch.
- These changes address spurious thread resumption and lost messages, especially when TX_NOT_INTERRUPTABLE is enabled.
- These changes ensure that pending interrupts (specifically PendSV) are recognised before subsequent instructions are executed, following Kairalite's feedback and ARM architectural guidelines.

-----
* Added a comment in common/tx_queue_cleanup to document why the NI path omits revalidation guards
- In `TX_NOT_INTERRUPTABLE` mode, the caller keeps interrupts disabled across the entire cleanup call, so the race window that makes the guards necessary in the interruptable path cannot occur. Add a comment explaining this, and noting that all paths that resume a suspended thread clear tx_thread_suspend_cleanup before calling
_tx_thread_system_ni_resume, making double-cleanup impossible.
This prevents future false-positive suggestions (e.g. from AI tools) to add redundant checks to the NI path.
