Documentation tooling:
- Add the `build-doc` skill and `tools/build_doc.py` wrapper for local
Sphinx builds (clean / -W / open).
- Enable Markdown (MyST) in conf.py and auto-collect
examples/{device,host,dual}/*/README.md into a 3-level Examples nav
(Examples > Device/Host/Dual > example), noting each page's source
location and normalizing headings to a single H1.
- Remove the stale `.claude/commands/build-doc.md`; point the AGENTS.md
Documentation section at the skill.
Example docs:
- Add a README.md for every device/host/dual example: what it does, USB
interface table, notable tusb_config.h settings, generic CMake + Make
build steps, and how to try it.
- Fold each *_freertos variant into its base README, noting the FreeRTOS
source path and any RTOS-specific behavior.
Generated docs/examples/ output is git-ignored. Builds clean with
`sphinx-build -W`.

The BSP family and MCU option were named "ch58x"/"CH58X", but the supported part is
the CH583/CH582 (and the SDK repo is openwch/ch583); CH585 is a separate MCU family,
so the CH58x umbrella was misleading. Rename to the specific family:
- hw/bsp/ch58x -> hw/bsp/ch583 (dir), and the BSP-local files ch58x_it.* ->
ch583_it.*, system_ch58x.* -> system_ch583.* (include guards/refs updated). The
vendor SDK files (CH58x_common.h, CH58x_*.c in hw/mcu/wch/ch583) keep their names.
- OPT_MCU_CH58X -> OPT_MCU_CH583 in tusb_option.h, tusb_mcu.h, and the shared WCH
USBFS driver (ch32_usbfs_reg.h, dcd_ch32_usbfs.c). OPT_MCU_CH582 is kept as an
alias (same value), so either name selects the same code.
- FAMILY_MCUS CH58X -> CH583, CFG_TUSB_MCU=OPT_MCU_CH583, mcu:CH58X -> mcu:CH583 in
the example skip lists, the CI build matrix (ci_set_matrix.py), the get_deps family
tag, and docs/reference/boards.rst.
Board names (ch582m_evt, yd-ch582m) are unchanged. Verified: make + cmake build for
ch582m_evt, and ci.lan HIL (all device examples pass).

CH58x has no isochronous support (dcd_edpt_iso_alloc() returns false), but the
audio class ignores that result and the endpoints fall back to capped 64-byte
non-iso transfers, producing non-functional audio firmware. video_capture and the
FreeRTOS audio examples already carry mcu:CH58X; add it to the remaining iso
examples (audio_test, audio_4_channel_mic, audio_test_multi_rate, cdc_uac2,
uac2_headset, uac2_speaker_fb) so they are not built for CH58x.
Found by Codex review. Verified via build_utils.skip_example() that all six now
skip on ch582m_evt while control examples (e.g. cdc_msc) still build.

Fix one direction endpoint examples

fix: BE bitfield guards for audio structs and endian-safe wValue/wIndex extraction in UAC2 examples
|
|
Enabling the audio test fleet-wide surfaced failures on esp32-p4/s3 and
metro_m4_express: the UAC mic enumerates but arecord fails the iso IN read
with EIO, while 18 other boards pass strict=1.000.
esp32: root cause is the FreeRTOS tick rate. ESP-IDF defaults
CONFIG_FREERTOS_HZ to 100, so the audio task wakes only every 10 ms and
can't service the 1 ms UAC iso frames -> underrun -> arecord EIO. (The same
dwc2 driver passes on STM32, whose FreeRTOSConfig is 1000 Hz.) Set
CONFIG_FREERTOS_HZ=1000 in the example sdkconfig.defaults; the example
defaults are honored in the generated sdkconfig alongside the BSP's, so this
takes effect.
metro_m4_express (samd51): not tick-rate -- its FreeRTOSConfig is already
1000 Hz like the passing boards -- so it's a separate iso-IN issue, skipped
for now.

The audio20 get/set entity dispatchers already extract entity_id from
wIndex and route to the matching clock / feature-unit helper, so each
helper's own entity_id re-derivation and TU_ASSERT(entity_id == ...) was
dead: the helper is only ever reached for its one entity. Unknown
entities are still rejected by the dispatcher's "not handled" path.
Remove the redundant local, the dead assert, and the constant "entity"
field from each helper's not-supported log (the message text already
identifies the entity). The local is dropped entirely rather than kept
for the log, since TU_LOG1 compiles out in release and would leave it
unused.

* test/hil: replace build.flags_on with named variant schema
Boards declare build variants as `variant: [{name, flags}]` instead of
`build.flags_on`. The variant `name` is the build dir (cmake-build-<name>) and
the HIL report row; `flags` is the raw CFLAGS string (-D...=1) injected via
CFLAGS_CLI. No `variant` => a single build named after the board.
- build.py: --build-name <name> (dir) + --cflag=<token> (raw CFLAGS, repeatable,
=form survives the matrix's shell word-splitting); drop -f1/CFLAGS wrapping.
- hil_ci_set_matrix.py: emit one build arg per variant.
- hil_test.py: iterate variants; report row + build dir = variant name.
- hil_ci.sh: copy all cmake-build-<board>* dirs for -b runs.
- get_deps.py: accept (ignore) --build-name/--cflag from matrix args.
- tinyusb.json: migrate all 6 flags_on boards to variant.
* board_test: park CI build with busy spin instead of wfe

- examples/device/midi2_device/src/main.c: drop the unreachable
`return 0;` after the `while(1)` superloop. IAR with
--warnings_are_errors rejects Pe111 (statement is unreachable);
C99 lets `int main` fall off the end, matching midi_test.
- examples/host/msc_file_explorer_freertos/skip.txt: skip
stm32h7s3nucleo. The board has only 64 KB on-chip FLASH and the
FreeRTOS + FatFS host MSC explorer now overflows by ~248 bytes
after the async control queue refactor.

iccarm rejects -Wno-type-limits, breaking the hil-hfp-iar CI matrix
(stm32l412nucleo, stm32f746disco, lpcxpresso43s67). Apply the same
CMAKE_C_COMPILER_ID guard used in hw/bsp/family_support.cmake so IAR
builds skip the flag without losing the GCC warning suppression.

stm32h573i_dk, stm32n657nucleo and stm32n6570dk have the same
pre-existing uninitialized io_ctx.GetTick in their board.h that we
already skip on stm32h7s3nucleo. Trips with Make+LTO; CMake passes.
|
|
arm-clang fails with -Werror=unused-function; arm-gcc was silently
omitting it via LTO. The helper was never called.
|
|
Make build was missing midi2_device.c/midi2_host.c from
src/tinyusb.mk. Skip stm32h7s3nucleo board which exposes a
pre-existing uninitialized warning in its board.h (board_init2)
under Make+LTO.
|
|
Restrict midi2_host build to MCUs with USB host support (cloned from
midi_rx) and skip SAMD11 from midi2_device (ROM overflow on link).
|

Remove the rp2040-only guard; the example now follows the audio_test
pattern (only Espressif uses its own build system). Add CMakePresets.json
and generic product strings.
The runtime fallback picks the path that matches the host state, per
message, mirroring the idea behind the UAC examples:
Alt 0 USB-MIDI 1.0 32-bit Event Packets (packet_write)
Alt 1 + MIDI 1.0 negotiated UMP MT 0x2 (ump_write)
Alt 1 + MIDI 2.0 negotiated UMP MT 0x4 (ump_write)
Build-tested on rp2040, rp2350, stm32f0/f1/f2/f3/f4/f7/g0/g4/h5/h7/l0/l4/u0/u5/wb/c0,
samd2x_l2x, samd5x_e5x, same7x, nrf, imxrt, lpc17, lpc55, mcx, ra,
da1469x, efm32.

- Use UINT32_C(1) instead of 1u for bit shifts >= 16 in
midi2_device.c to avoid shift-count-overflow on 16-bit
platforms (MSP430)
- Add Makefiles for midi2_device and midi2_host examples with
family guard (skip if FAMILY != rp2040). These examples
require Pico SDK and board-specific hardware
- Restrict midi2_device CMakeLists.txt to rp2040 family
(matching midi2_host)

Add Device example that plays Twinkle Twinkle Little Star using native
UMP format. Demonstrates all MIDI 2.0 Channel Voice message types:
16-bit velocity, 32-bit CC, 32-bit pitch bend, 32-bit channel/poly
pressure, per-note management, program change with bank select, and
JR timestamps.
USB descriptor exposes both Alt Setting 0 (MIDI 1.0) and Alt Setting 1
(UMP) per USB-MIDI 2.0 specification.
Tested on: Raspberry Pi Pico (RP2040), Linux (ALSA), Windows (MIDI
Services)
