tools: support RTT capture lifecycle on Windows

2026-09-01T02:55:11Z

Use platform-specific process group creation and termination so J-Link, OpenOCD, and dump helpers are retired reliably on Windows as well as POSIX. Resolve Windows executable names while preserving environment overrides and report missing tools cleanly. Add an optional stop file for ending indefinite captures from automation without signals. Cover executable selection, process cleanup, and stop-file handling in the RTT HIL tests.

pico2_etm_trace: RP2350 board on the MIPI-20 ETM trace carrier

2026-08-28T18:08:31Z

Board files for the trace carrier (console GP12/13, LED GP10, I2C GP8/9, PIO-USB host on GP20, all retargeted in board.cmake so the SDK defaults cannot mux a trace pin), compile-time trace pin-conflict checks, the measured DBGPAUSE rationale, Ozone project, and skill/docs updates. Trace validated at the stock 150 MHz (75 MHz TRACECLK, +1 ns sampling): zero overflow through a 15 s throughput soak; V2 probe ceiling 120 MHz.

Add RTT console/capture tooling (tools/rtt.py), rtt skill, and HIL harness support (#3853)

2026-08-28T07:16:02Z

Promote SEGGER RTT from an inline debugging technique to a standalone skill backed by one stdlib-only implementation in tools/rtt.py: a CLI and importable module for console/capture over J-Link (RTTTelnetPort) and OpenOCD (rtt server) probes, with probe selection by serial or VID:PID, control-block address via --elf or --addr, bidirectional console, post-mortem ring dump, and --reset-before-attach for boot-time capture. The HIL harness reads a board's console over RTT when its probe has no VCOM ("logger": "rtt" plus a LOGGER=rtt variant define), covering device_info, pool-check aliveness, and CI wiring. Validated on 22 boards across both backends; 26 unit tests run in pre-commit.

ci_select: fix the membrowse test's env dependence, and stop HIL unit tests taking the rig (#3846)

2026-08-25T03:35:45Z

test_the_upload_board_can_diverge_from_the_built_board called get_family_boards without ci=True, so it pinned the developer's set, not the runner's: the CI skip lists move the one-first pick on three families. It held locally and went red on its first CI run. Pass ci=True, as _prune_buildable already does, and pin the runner's twelve. Rule 2 is a bare test/hil/ prefix, so the harness's own unit tests booked the full 27-board rig for diffs that cannot reach it. Carve test/hil/test/** out to rule 1b, beside test/{fuzz,unit-test}/**; the harness itself is untouched. A test pins that directory's file list, so anything added there that the rig does read fails rather than silently skipping hardware. Rule table updated in the spec and its carbon in the docstring.

ci: an empty selection must build nothing, plus selector follow-ups (#3845)

2026-08-25T02:46:42Z

ci: an empty selection must build nothing, plus selector follow-ups A PR whose build axis legitimately selected nothing rebuilt everything. build.yml reads .build.families twice - as a |-joined regex, and implicitly as "is anything selected" - but tested only -z "$FAMILY_REGEX", which an empty list and a charset-rejected one both satisfy while meaning opposite things. ci_set_matrix had already returned the correct all-empty matrix; the fall-open branch discarded it. #3842 and #3840 each spent 74 cmake legs on it. Branch on the two cases instead, rename FAM_* to FAMILY_*, and cover the block with a test that extracts it from build.yml and executes it - it had no test at all, which is how this shipped through two merges. Follow-ups to the same machinery: glob.escape the repo root at five sites, so a checkout path containing [ or * stops failing closed; drop the ci-full label, read after the matrix was already computed and so never functional; delete 13 mcu:MKL25ZXX / mcu:SAME5X skip tokens matching no board; carry the rule table in the module docstring, guarded against drift; and pin six selection behaviours a mutation pass proved untested. Cut the selector's cost 1.8x (26.0s -> 14.6s) with 0 divergences over 260 paths, and stop scoping the membrowse upload by the PR example filter.

ci_select: address Copilot review - anchor _META_RE, cover rule 12b

2026-08-22T16:10:14Z

Anchor the .github file alternatives. FUNDING.yml, labeler.yml and membrowse_pr_message.j2 sat inside a group whose only `$` belonged to the workflows/ branch, so they matched as prefixes: .github/labeler.yml.bak and .github/FUNDING.yml.old were classified as metadata and would have selected nothing. No such file exists today - the workflows/ alternative was already anchored and ISSUE_TEMPLATE/ is a directory prefix on purpose. Rule 12b had no test of its own: TestNoTrackedFileIsUnclassified only proved src/typec no longer reaches rule 17, not that the answer is right. TestTypecRule pins it - non-full, every selected example under typec/, all four src/typec files answering alike, no rig board, and the set derived from CFG_TUC_ENABLED rather than hardcoded, so it follows a new typec example on its own. Verified all four fail with rule 12b removed.

build_utils: key the caches on the tree, not just the arguments

2026-08-21T16:14:25Z

The eight lru_cache layers take repo-RELATIVE paths - 'hw/bsp/', 'examples//skip.txt', the literal 'hw/bsp' glob - while ci_select._in_repo() chdirs around every call so one process can classify more than one tree. With no cwd in the key the second tree gets the first tree's answers. Reproduced: skip_example('host/bare_api','metro_m0_express') is False at the repo root and STILL False after chdir into a tree where that board does not exist; only cache_clear() gave the right answer. It bites the code-size skill's base-vs-branch worktree compare, /pre-pr, and the first test that points classify_build at a fixture tree. Master had no caching here, so the hazard arrived with it. _cwd_cache puts os.getcwd() in the key. The 199-test suite passed before only because every test happens to pass the real REPO; the new TestCachesAreKeyedOnTheTree crosses trees deliberately. Also adds the drift guard the class rule was missing. Ports, hw/mcu, get_deps tokens and bsp families each have one; the class rule had only a comment claiming vendor_host.c was the sole "enabled by no example config" case until its removal - which src/class/bth falsifies today. TestClassesWithNoEnablingExample pins the set to {bth}, so a class added before its first example, or an example config flipped to 0, fails here instead of silently selecting nothing on both axes. Verified it fires by adding a class dir nothing enables.
