Merge paired FreeRTOS/no-OS device examples into their base directories.

Improve Espressif example build selection

2026-06-29T12:06:05Z

Default Espressif builds to FreeRTOS, discover ESP-IDF examples from component metadata, and make skip filtering RTOS-aware.

docs: add build-doc tooling and a README for every example

2026-06-29T03:16:25Z

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`. Co-Authored-By: Claude Opus 4.8 (1M context)

hw/bsp+wch: rename the CH58x family to ch583 and OPT_MCU_CH58X to OPT_MCU_CH583

2026-06-22T08:23:08Z

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). Co-Authored-By: Claude Opus 4.8 (1M context)

examples: skip isochronous audio/UAC examples on CH58X

2026-06-20T16:37:23Z

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. Co-Authored-By: Claude Opus 4.8 (1M context)

test/hil: fix esp32 audio_test_freertos (FreeRTOS tick), skip metro_m4

2026-06-18T12:36:00Z

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.
