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.

- 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.

- 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.

- Removed `pyfatfs` dependency in favor of `mtools` for reading FAT volumes, simplifying the block device read logic.
- Updated `requirements.txt` and added detailed host setup instructions for system packages.
- Switched to `cython-hidapi` for HID tests, replacing deprecated APIs with updated usage.
- Removed unnecessary warnings suppression and `fs` module.

ch32_usbhs: fix endpoint stall length index and clear-stall response
|
|
|
|
|
|
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.

fix(dcd_ch32_usbfs): fix dropped bulk OUT packets by properly re-arming EP_RX_CTRL state
|

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.

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.

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.
