test/hil: add board-pool health check, split hil_test into focused modules (#3794)
Add test/hil/hil_pool_check.py: per-board rig health scan — probe presence,
light-example flash (dfu_runtime; device_info + serial check for host-only
boards), uid re-enumeration, safe recovery (probe authorized-toggle, board
reset), verified board_test re-park, USB topology report, and a markdown
summary table. Missing firmware is built on the spot (tools/build.py, idf.py
for espressif, one get_deps retry); row statuses: ok, flash-failed, failed,
locked. Board locks are always respected, never bypassed.
Refactor hil_test.py into hil_lock.py (flock protocol, controller permits,
hold/release/status CLI; replaces board_lock.py) and hil_flash.py (flashers,
find_firmware, run_cmd). Update WCH probe uids and the board roster in
tinyusb.json; add the hil-pool-check skill.docs: add the unified OpenOCD plan, note worktree dep symlinks2026-07-28T07:43:32Zhathachthach@tinyusb.org2026-07-28T07:43:32Zurn:sha1:3fdd294b95143f909a6c991943a2e55e638b177a
The plan doc records why the fork exists and how each vendor source was
ported; the interim handoff it superseded is dropped.
CLAUDE.md: a new worktree should symlink the dependency dirs to the
primary checkout rather than re-fetching them, replacing a single
symlink only when the branch needs a different dep revision. Also allow
'linke' in codespell - WCH-LinkE is a product name.

docs(skills): debug-skill overhaul — role-neutral capture model, verified debugger arsenal, Espressif backenddocs: address Codex/Copilot review on #37862026-07-24T08:14:02Zhathachthach@tinyusb.org2026-07-24T08:14:02Zurn:sha1:154999dbac95484f3f9a02cbf7a7277d89e1e0e9
- target-debug: fault frame lives on PSP when EXC_RETURN bit2 set (FreeRTOS
tasks) — decode LR before choosing $msp/$psp (Codex; valid, our verify
happened to fault on MSP)
- esp-target-debug: show the Xtensa gdb for S3 in the attach recipe; clarify
adapter serial = USB-SJ iSerial (colon MAC, hardware-verified) vs the
CP2102N flasher uids in tinyusb.json (Codex; second half of the finding
had the identifiers inverted)
- esp plan: align serial form with the verified command; record the real
console-gate outcome (UART0, USB-SJ console untested) (Copilot)
- target-debug plan: Task 4 now consistently $JB/ARMv7-M matching the
executed JLinkExe path (Copilot)
- drop IDE-local .idea files swept in by the rename commit (Copilot)
docs(superpowers): esp-target-debug design spec + executed implementation plan2026-07-24T07:55:59Zhathachthach@tinyusb.org2026-07-24T07:55:59Zurn:sha1:df3cea3d0e12c155e2a2e7f81dec031da38ab328
Spec (brainstormed): own-skill backend decision, PHY-conflict map, six
verification gates, external-JTAG TODO. Plan executed same-day: all gates
run on the rig; apptrace resolved per its own gate rule as (untested).
docs(target-debug): vector catch, SWO trace, verifybin, FreeRTOS threads; table integration2026-07-24T07:55:59Zhathachthach@tinyusb.org2026-07-24T07:55:59Zurn:sha1:21bbcb5bbff18454979a1dc9aaa210e938a004b5
- Vector catch + Cortex-M fault autopsy, verified with a deliberate bad-load
on stm32f407disco: CFSR=0x8200 (BFARVALID|PRECISERR), BFAR = exact bad
address, stacked pc addr2lined to the faulting line; gotchas recorded
(stale FPB comparators fire phantom SIGTRAPs — scrub first; arm DEMCR
after reset; loads precise / stores imprecise; ARMv6-M has no CFSR/BFAR)
- SWO exception trace + hw PC sampling gate PASSED on F407: 680 KB of
packets in 3 s (0x17 PC samples in flash range, 0x0E SysTick enter/exit);
JLinkSWOViewerCL decodes stimulus only — raw SWORead is the recipe;
SWOStart needs an explicit speed headless
- verifybin 'Verify successful.'; FreeRTOS -rtos plugin lists all 6
cdc_msc_freertos tasks after a run->stop cycle (plain attach = 0xDEAD
placeholder); semihosting anti-note; monitor-mode pointer (untested)
- Intrusiveness table gains the new rows; agent playbook bullet updated;
retrieval gate 5/5 with a fresh reader; executed plan committed

- getting_started.rst: the reST inline-link markup rendered literally
inside the code-block (not a runnable command) and lacked sudo — use a
plain `sudo cp examples/device/99-tinyusb-examples.rules ...`.
- tools/88-tinyusb.rules: normalize the six MODE="666" entries to the
4-digit octal MODE="0666" used everywhere else in the file.
