Complete the khci -> chipidea ci_fs migration that was started for device
(commit d70403f1f "host is not yet"):
- device: switch kinetis_k/kl/k32l (Makefiles + k32l CMake) to dcd_ci_fs.c
- host: add hcd_ci_fs.c (port of hcd_khci.c onto ci_fs_regs_t) and switch all
Kinetis families to it; remove src/portable/nxp/khci entirely
- enable host examples (device_info, cdc_msc_hid) for mcu:KINETIS_K
- README: merge the KL and K32L2 rows into a single "KL, K32L" ci_fs row
hcd_ci_fs.c also fixes two pre-existing host bugs found via HIL on frdm_k64f
(present in the old hcd_khci.c too):
- data toggle was flipped on a NAK in suspend_transfer; a NAK transfers no
data so the toggle must be preserved, else the retried bulk packet is
silently discarded by the device (MSC CBW/CSW hang). See comment in file.
- prepare_packets asserted and dropped a transfer when the single shared BDT
was still owned by an in-flight transfer under concurrent activity; now it
returns busy and resume_transfer defers/retries on the next SOF.
HIL verified on frdm_k64f: device 13/13, host cdc_msc_hid (CDC mount + echo +
MSC mount, through a hub).

- Order CFG_TUH_DEVICE_MAX before CFG_TUH_HID in the host config snippets
(cdc_msc_hid, hid_controller) so the documented snippet has no forward
macro reference when copied into tusb_config.h.
- Fix stale `examples.rst` references: the generator now writes per-group
`docs/examples/<group>/index.rst` pages, so update the conf.py comment and
the build-doc SKILL.md accordingly.

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 variable is set in mount/umount callbacks but not read elsewhere
in the example (rx_cb already receives idx as a parameter). IAR
treats Pe550 as an error under --warnings_are_errors. Tag it
TU_ATTR_UNUSED so the example still shows the pattern of tracking
the device index without erroring on unused-set.

Same fix as midi2_device — IAR rejects the unreachable statement
after the while(1) superloop. Let int main fall off the end.
Co-Authored-By: Claude Opus 4.7 <[email protected]>

- 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.

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.
|
|
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).
|
|
Drop Feather-specific scaffolding (SSD1306 display, font, PIO-USB pin
override) and rename the directory to midi2_host. The example is now a
single main.c + tusb_config.h pair following the midi_rx pattern, with a
printf-only UMP decoder for Channel Voice messages.
Build-tested on adafruit_feather_rp2040_usb_host, daisyseed (stm32h7),
mimxrt1010_evk, stm32f407disco, raspberry_pi_pico2, b_u585i_iot2a,
portenta_c33, stm32h503nucleo, stlinkv3mini, feather_stm32f405.

Remove the Waveshare RP2350-USB-A host example and board definition.
The Feather RP2040 USB Host is the TinyUSB reference board for
PIO-USB host and does not require the CFG_TUSB_DEBUG workaround
needed by the Waveshare (R13 pull-up issue).
One host example is sufficient for the PR. The Feather variant has
an improved display with splash, spinner, and 6-line live view.
|
|
The Makefile was missing the FAMILY=rp2040 guard, causing CI failures
on stm32h7rs and other non-RP2040 targets. Matches the approach used
by midi2_host.
|
|
Board-specific variant of midi2_host targeting the Adafruit Feather
RP2040 with USB Type A Host (product 5723).
Hardware differences from the Waveshare RP2350-USB-A example:
- PIO-USB on GP16/GP17 (vs GP12/GP13)
- I2C1 via STEMMA QT on GP2/GP3 (vs I2C0 GP4/GP5)
- USB Host 5V power enable on GP18
Display uses three phases: splash screen, spinner while waiting for
a device, then live scrolling UMP message view with 6 visible lines.
Tested board-to-board: RP2040 Pico (Device) to Feather RP2040 (Host),
SSD1306 128x64 OLED showing decoded MIDI 2.0 messages in real time.

- 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)

Host driver (midi2_host.c):
- midih2_open() now returns actual parsed length instead of max_len,
preventing composite device interface conflicts
- Parsers (alt0/alt1) refactored to return const uint8_t* end pointer
following midi_host.c switch/case pattern
- Alt 1 CS Endpoint now parses MIDI 2.0 layout (bNumGrpTrmBlk at
offset 3 with MIDI_CS_ENDPOINT_GENERAL_2_0 subtype check) instead
of reusing MIDI 1.0 struct (bNumEmbMIDIJack)
- midih2_set_config() now issues SET_INTERFACE control request via
tuh_interface_set() before completing configuration. Falls back to
alt 0 if SET_INTERFACE fails
- Extracted midih2_set_config_complete() and midih2_set_interface_cb()
for async SET_INTERFACE handling
Device driver (midi2_device.c):
- midi2d_open() skip loop now checks bInterfaceNumber, stopping at
interfaces that belong to other functions in composite devices
- SET_INTERFACE handler now rejects alt > 1 (returns false/stall)
- Named constants for GTB descriptor types and MIDI protocol values
Descriptor macros (usbd.h):
- TUD_MIDI2_DESC_ALT1_HEAD: iInterface set to 0 (consistent with
Alt 0), wTotalLength now uses TUD_MIDI2_DESC_ALT1_CS_LEN to cover
all Alt 1 class-specific descriptors
- TUD_MIDI2_DESC_ALT1_EP: now accepts GTB ID list via variadic args,
emitting complete CS endpoint descriptor
Host example:
- CMakeLists.txt restricted to rp2040 family (display.c requires
Pico SDK headers)
- display.c: null terminator after strncpy in log scroll
Documentation:
- class_drivers.rst updated to reflect SET_INTERFACE behavior and
auto-select with fallback

Add Host example that receives UMP from a MIDI 2.0 Device via PIO-USB
and displays received messages on a SSD1306 OLED (I2C, 128x64).
Features:
- Boot checklist on display (PWR, TinyUSB, USB bus, Device, Descriptor,
Alt Setting UMP, Mount, Receiving)
- Decode and display all MIDI 2.0 Channel Voice messages
- PIO-USB Host on rhport 1 (GP12/GP13 for Waveshare RP2350-USB-A)
- SSD1306 display via I2C0 (GP4=SDA, GP5=SCL)
Also add board definition for Waveshare RP2350-USB-A.
Tested: Waveshare RP2350-USB-A (Host) receiving UMP from Raspberry Pi
Pico (Device) via USB cable, notes displayed on SSD1306 OLED

IAR is only supported with CMake. Remove all IAR-specific references
from the Make build system including toolchain files, SRC_S_IAR,
LD_FILE_IAR variables, and IAR toolchain detection.
Also fix GET_SECTOR_COUNT truncation in msc_file_explorer and
broken formatting in stm32f7 board_uart_write.

Update FatFS to R0.16
|
|
|
|
|
|
- Add lib/fatfs to deps_mandatory in get_deps.py, pinned to R0.16
(commit 30ca13c6) from github.com/abbrev/fatfs mirror
- Move TinyUSB custom ffconf.h to examples/host/msc_file_explorer/src/
with project-specific settings: FF_CODE_PAGE=437, FF_USE_LFN=1,
FF_FS_RPATH=2, FF_VOLUMES=4, FF_FS_NORTC=1
- get_deps.py removes stock ffconf.h after clone to avoid conflict
- Remove vendored fatfs source files from git tracking
FatFS R0.16 includes important fixes since R0.15:
- Fixed FAT32 FsInfo regression (forced full FAT scan on f_getfree)
- Fixed f_readdir infinite loop (from R0.15b)
- f_getcwd/.. now works on exFAT
- Added FF_FS_CRTIME support
