2026-09-28Updated ThreadX version constants and port strings to 6.5.2.202603 (#781)Frédéric Desbiens
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.

2026-09-15Normalized the AI disclosure comment to one fixed line per file (#740)Frédéric Desbiens
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) <[email protected]>
2026-09-15Replaced the GNU-only dsb/isb 0xF operands with the UAL sy form (#729)Frédéric Desbiens
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`. Assisted-by: Copilot (Opus 5) <[email protected]>
2026-09-09Removed the vector table offset register and system stack pointer setup from ↵Frédéric Desbiens
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.

2026-09-09Marked every published ThreadX include directory as SYSTEM so applications ↵Frédéric Desbiens
no longer get warnings from ThreadX headers (#713) * Marked every published ThreadX include directory as SYSTEM so applications no longer get warnings from ThreadX headers Commit 8c3c08f added the SYSTEM keyword to the target_include_directories call in common/CMakeLists.txt, but the same call in every port, in the SMP common directory's consumers, in the POSIX and FreeRTOS compatibility layers, and for the generated tx_user.h directory was left unchanged. A consumer building with a strict warning set therefore still saw diagnostics coming from tx_port.h and from the compatibility layer headers, which is exactly what the original change set out to avoid. Added the SYSTEM keyword to all of those calls so CMake emits -isystem rather than -I for every directory holding a ThreadX public header. The ARMv7-M, ARMv8-M, ARMv7-A and ARMv8-A architecture sources under ports_arch were updated alongside the ports they generate, keeping the two in step. Directories that are PRIVATE to an example or test build were left as they are, since nothing is published from them. Fixes #290 Assisted-by: Copilot (Opus 5) <[email protected]> * Stopped apt-get update being a gate it was never meant to be apt-get update fails if any configured repository serves a bad index, including ones this project never reads. The GitHub runner image carries Google's and Microsoft's apt repositories, and a Hash Sum mismatch from Google's, their CDN caught mid-publish with the index and the Release file eight hours apart, failed all three attempts and turned a run red over a browser nobody was installing. Made a failed update warn and carry on, leaving apt-get install as the gate. Nothing is weakened by that: the install still exits on a package it cannot find, so an unreachable archive still stops the script, one step later and naming the package it could not get, which is a better diagnostic than a hash mismatch in a repository nobody asked for. Disabling third-party sources before updating would keep the update strict, but this script also runs on a contributor's own machine, and rewriting someone's apt configuration to suit CI would be worse than tolerating a stale index for an archive we do not read.

2026-09-03Fixed the incorrect loop bound constant in the IAR file lock support (#695)Frédéric Desbiens
The IAR multithreaded library support code allocates its file lock mutexes from an array of _MAX_FLOCK entries, but the wrap-around check and the exhaustion check in __iar_file_Mtxinit() both compared against _MAX_LOCK, the bound of the unrelated system lock mutex array. When _MAX_FLOCK is greater than _MAX_LOCK, the free mutex index wrapped early and the exhaustion check reported failure while free entries remained, so *m was set to TX_NULL and the application faulted the first time a file lock was taken. When _MAX_FLOCK is smaller than _MAX_LOCK, the free mutex index was allowed to run past the end of __tx_iar_file_lock_mutexes and the exhaustion check could never fire. Corrected all four comparisons in each of the 27 copies of tx_iar.c. Fixes #444 Assisted-by: Copilot (Opus 5) <[email protected]>
2026-08-11Removed developer machine paths from the shipped project files (#603)Frédéric Desbiens
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.

2026-08-10Completed the Cortex-M0 barriers and made its example build with both ↵Frédéric Desbiens
toolchains (#595) Two unrelated Cortex-M0 gaps, both left over from earlier work. The memory barriers from #523 reached the Cortex-M0 gnu port but not its ac6 or iar siblings, in either the inline system return in tx_port.h or the assembly routine. Both take the same GNU or IAR code path, and iar already carried the entry barrier, so the missing pieces were the entry pair for ac6 and the barrier after restoring the interrupt posture for both. All three tools now match. The Cortex-M0 example could not link with any toolchain. cortexm0_crt0.S references 23 linker script symbols and the script defined only 12 of them, so __text_start__, __text_end__, __text_load_start__, the rodata and fast section symbols, and the ctors and dtors load addresses were all unresolved. The Cortex-M4 script defines all 23, including a .fast section with no content whose symbols exist so that the startup copy is a no-op, and its comment says as much. The Cortex-M0 script is brought to that same shape. That left the example failing under LLVM only, on instructions that ARMv6-M can encode just one way. The file declared .code 16 but no syntax mode, so GNU as used the legacy divided syntax in which a plain add or sub sets the flags implicitly, while LLVM implements unified syntax only and rejected the non-flag-setting spelling. Declaring .syntax unified and writing movs, adds and subs makes both assemblers agree, and the encodings GNU produces are byte identical before and after, verified by disassembling both objects. The Cortex-M0 example now links with GNU at 22,520 bytes of text and with Arm Toolchain for Embedded at 22,866, so it comes off the list of examples not expected to link and scripts/check_clang.sh now links eight of eight.

2026-04-29Fixed race condition and message loss in Cortex-M ports (#523)Frédéric Desbiens
* 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. Assisted-by: Gemini (Gemini 2.0 Flash) ----- * 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. Relates to: eclipse-threadx/threadx#516 Co-authored-by: Copilot <[email protected]>

2023-06-21SysTick initialization problem fixed in tx_initialize_low_level.sAlex Kiselev
Problem with first system tick was detected, it needs much more time for the first tick as it's defined. The reason for this behavior is incorrect initialization of the SysTick timer in the port file for the Cortex-M0. It doesn't reset the SysTick Current Value Register despite the fact that its value is not initialized at startup (see https://developer.arm.com/documentation/dui0552/a/cortex-m3-peripherals/system-timer--systick). So if we have 0xFFFFFF (this register has 24-bit), it means we will get about 256*256*256 / 48000000 for the tact frequency of 48MHz to reach the zero, that makes 350ms delay at startup.
