Cast DOEPDMA0 through uintptr_t and use sizeof(tusb_control_request_t)
instead of the magic constant 8, matching project convention. Add a
reference to Programming Guide v4.20a 9.1.2.1 for the DOEPDMAn-8 rule.
Addresses Copilot review comment; no functional change.

core v3.10a (STM32L476)
DWC2 core rev 3.10a pushes an extra EP0 RX_COMPLETE (RXFLVL PKTSTS 0x3)
that is not a real OUT data completion, in two cases flagged on DOEPINT:
- STPKTRX (Setup Packet Received): between SETUP_RX and SETUP_DONE
- STSPHSRX (Status Phase Received, control write): after the OUT data
stage when the host starts the IN status phase

Add control transfer fifo for host stack
|
|
|
|
- src/tusb.c: extend tu_str_xfer_result[] with "ABORTED" and "INVALID"
to match the new enum size. Not reachable today (no HCD posts those
values through hcd_event_xfer_complete), but keeps the enum/table
invariant intact so future HCDs that surface ABORTED don't index OOB.
- examples/dual/dynamic_switch/src/main.c: apply the same while(1)
hoist already done for cdc_task / print_devinfo_task to
led_blinking_task. On OS_NONE the loop returned mid-iteration, which
on first call could fire multiple back-to-back toggles while
start_ms (initially 0) caught up to uptime.

Fix premature MTP phase change after short MTP OUT transfer
|
|
|
|
To avoid STATUS IN completion of previous control transfer treated as next DATA IN when IRQ latency is high.

Handle OUT transfer differently from IN to not prematurely change MTP phase when host sends short packet that is not end of MTP data phase. Only reaching container length or ZLP should change phase.
|
|
- Added a pending FIFO queue for asynchronous control transfers when the active slot is busy.
- Introduced `control_xfer_dispatch_pending` to handle queued transfers on slot availability.
- Improved synchronization for blocking and non-blocking transfer modes, preventing deadlocks in RTOS.
- Refactored and renamed related functions for clarity and consistency.
- Enhanced error handling and callback invocation for failed or stale transfers.
|
|
|
|
- GRXSTSP register has internal FIFO, receiving events won't mix up (STATUS OUT & next SETUP)
- Improve efficiency, remove 2nd IRQ overhead

Fix issue in the stall handling:
- dcd_edpt_stall() for an IN endpoint cleared EP_TX_LEN(0) instead of
EP_TX_LEN(ep_num), clobbering endpoint 0's transmit length register
when stalling any other IN endpoint.

Refactor the driver to follow USBFS style for easier maintenance.
Replace the old packet/response helpers with explicit queue and update paths for IN and OUT transfers.
Introduce transfer validity tracking and per-endpoint data toggle state.
Reset toggle state on init, close-all, endpoint close, clear-stall, and bus reset.
Initialize endpoint controls consistently in NAK + TOG_0 mode.
Tighten EP0 setup/status handling and route transfer IRQ processing through the transfer-flag path.
Stop enabling ISO_ACT in INT_EN and clear unhandled interrupt flags explicitly.

It would casue race condition, SETUP packet is always acked.

feat: Add USB-MIDI 2.0 Device and Host class drivers

Default RX/TX buffers to EPSIZE for both device and host. Document
drain-in-loop on ump_read; example device callback drains until
empty.
|
|
Match midi2_host pattern. Literal 256 underran HS endpoints (512B).
|
|
Lets each instance return different NUM_GROUPS, NUM_FUNCTION_BLOCKS,
EP_NAME and PRODUCT_ID. Defaults fall back to the macros.
|
|
MT is in byte 3 of the UMP word in LE memory, not byte 0. Buffers
at mps blocked RX xfer re-arm on partial packets.

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.
|
|
The edpt_stream auto-flush is byte-oriented and could cut an UMP message
in half when the FIFO reached wMaxPacketSize, corrupting the peer's RX
context. Pre-flush whole packets before writing one that would cross the
boundary on both device (tud_midi2_n_ump_write) and host
(tuh_midi2_ump_write) paths. Host write also becomes packet-aware
instead of word-by-word.
Ref #3571

Alt 0 carries USB-MIDI 1.0 32-bit Event Packets, not UMP words; calling
the UMP API there would misinterpret the stream. Expose MIDI_PROTOCOL_MIDI1
and MIDI_PROTOCOL_MIDI2 in the public header so applications can branch on
the negotiated protocol.
