fix(stm32_fsdev): don't enable the unused USB wakeup EXTI IRQ (F1/F3/G4/L1)
2026-06-18fix(stm32_fsdev): don't enable the unused USB wakeup EXTI IRQ (F1/F3/G4/L1)hathach
The classic-USB STM32 fsdev driver enabled the EXTI-line USB wakeup interrupt (USBWakeUp_IRQn, and USBWakeUp_RMP_IRQn on the F3 remap path) in the NVIC, but never uses it: resume is serviced in-band via ISTR.WKUP in the USB_LP/HP ISR, and the driver never arms or clears that EXTI line. The wakeup EXTI interrupt is only needed to wake the core from STOP mode, which TinyUSB does not implement. Leaving its NVIC vector enabled lets it fire spuriously into an unhandled or looping vector -- the freeze reported in #3696 on STM32G473. USBWakeUp_IRQn is a valid, dedicated USB-wakeup-via-EXTI interrupt (e.g. stm32g473xx.h: =42 "USB Wakeup through EXTI line"), not an "unrelated interrupt"; it is simply unused here. - Comment out USBWakeUp_IRQn for F1/F3/G4/L1 and USBWakeUp_RMP_IRQn on the F3 remap path, kept in place so STOP-mode wakeup is a one-line re-enable. - Keep the STM32L1 USBWakeUp_IRQn -> USB_FS_WKUP_IRQn alias for that re-enable. - Document the rationale in fsdev_stm32.h with a TODO. - Comment out the matching USBWakeUp(_RMP)_IRQHandler in the F1/F3/G4 BSPs, and the FreeRTOS NVIC_SetPriority(USBWakeUp_IRQn) on F1/G4.

2026-06-18dcd/ch32_usbfs: support CH32V103 combined endpoint control registerhathach
CH32V103 uses the older USBFS IP: a single combined UEPn_CTRL register per endpoint (IN response in bits [1:0], OUT response in [3:2], shared auto-toggle, separate IN/OUT toggles) instead of the separate UEPn_TX_CTRL/UEPn_RX_CTRL bytes of the newer IP (CH32V20x/V307). The shared driver was written for the newer IP, so EP0 control transfers never worked on V103: the OUT response was written to a reserved byte and the IN write clobbered the OUT bits. - ch32_usbfs_reg.h: annotate the V103 register struct with byte offsets and add a union exposing the combined UEPn_CTRL at the UEPn_TX_CTRL offset; define CH32_USBFS_EP_CTRL_COMBINED and the combined-register bit positions. - dcd_ch32_usbfs.c: abstract EP control access behind ep_tx/rx_ctrl_set() (full write) and ep_tx/rx_set_response() (response-only RMW). The newer-IP path is unchanged; the combined path read-modify-writes the single register and arms the post-SETUP data stage at DATA1. - bsp/ch32v10x: implement board_get_unique_id() (real chip UID) and drop the CSR 0x800 writes that corrupted the QingKe V3 interrupt config and left all interrupts disabled (the USB ISR never ran). Verified on ch32v103r_r1_1v0: enumerates and passes HIL for cdc_msc, hid, msc, midi, mtp, dfu, etc. Co-Authored-By: Claude Opus 4.8 (1M context) <[email protected]>

2026-06-11Fix stm32f723disco host/cdc_msc_hid HIL: UART RX starvation + DWC2 DMA ↵Ha Thach
split-IN NAK storm (#3677) Fix stm32f723disco host HIL: UART RX starvation + DWC2 split bulk NAK/XactErr handling (#3677) stm32f7 BSP — UART RX starvation - The host console USART shared interrupt priority with the USB OTG ISR, so a long OTG interrupt could starve RXNE and drop received bytes. Raise the USART RX IRQ above OTG_FS/OTG_HS in both the bare-metal and FreeRTOS init paths, guarded by #ifdef UART_ID so boards without a UART console keep the default OTG priority. dwc2 host — split NAK/XactErr handling - Slave mode: a persistently-NAKing split bulk/control IN poll re-armed the start-split immediately, storming the ISR and starving task context. Throttle by disabling the channel and re-arming on the resulting halt (no frame deferral). - Buffer-DMA mode: a pure split bulk-OUT NAK was unhandled, leaving the channel halted and stalling the transfer — the dominant cause of CDC echo truncation. Handle it by rewinding the buffer pointers and retrying the start-split (Programming Guide v4.20a 5.1.4.2). - Buffer-DMA mode: a split bulk-OUT XactErr was retried immediately, exhausting HCD_XFER_ERROR_MAX before the transient cleared. Throttle via channel_disable + re-arm to give the hub TT a recovery gap, mirroring slave mode. - All three are scoped to split transfers (hcsplt.split_en); non-split NAK/XactErr keep the core-handled / immediate-retry behavior. The OUT XactErr throttle also excludes periodic split, where channel_disable() is a no-op and would wedge the channel. The nak_disabled flag is generalized to retry_disabled and honors xfer->closing so an endpoint close during a throttled retry tears down cleanly. Verified on stm32f723disco HIL (slave + CFG_TUH_DWC2_DMA_ENABLE): host/cdc_msc_hid, msc_file_explorer, and device_info all pass on both variants; DMA CDC echo went from ~15-25% raw failure to 10/10 clean.

hil: park boards with idle board_test instead of erasing flash
2026-06-08presets,hil: keep Ninja Multi-Config; make HIL find its outputhathach
Per review (HiFiPhile): Ninja Multi-Config is needed for IAR, otherwise the optimization level can't be lowered to none for debug. Revert gen_presets.py back to Ninja Multi-Config (keeping only the cmake-build-<board> binaryDir change), and instead teach hil_test.py to locate <ex>.elf whether it sits directly in the example dir (single-config) or under a per-config subdir like RelWithDebInfo/ (multi-config). Verified: stm32u083nucleo passes 13/13 remote HIL with a multi-config preset build (rsync preserves the RelWithDebInfo/ subdir; the resolver finds it).

2026-06-08tools/gen_presets: build into cmake-build-<board> with single-config Ninjahathach
Change the default configure preset binaryDir from build/<board> to cmake-build-<board> (the dir name HIL expects) and switch the generator from Ninja Multi-Config to single-config Ninja. Multi-Config nests binaries under a RelWithDebInfo/ subdir, which hil_test.py does not look in; single-config emits device/<ex>/<ex>.elf so preset-built firmware is directly consumable by `hil_test.py -B examples`. Regenerated BoardPresets.json (also picks up the tracked ch32v103c_bluepill board that was missing from presets). Co-Authored-By: Claude Opus 4.8 (1M context) <[email protected]>
2026-06-08stm32u0: implement board_get_unique_id from UID_BASEhathach
Previously stm32u0 had no board_get_unique_id(), so it fell back to the weak default in hw/bsp/board.c and every board reported the placeholder USB serial 0123456789ABCDEF. HIL identifies boards by USB serial, so a non-unique serial collides on a multi-board rig. Read the 96-bit unique ID from UID_BASE, mirroring stm32u5. Verified on stm32u083nucleo: now enumerates as 300044000D5036394E373620. Co-Authored-By: Claude Opus 4.8 (1M context) <[email protected]>

2026-05-12refactor: replace midi2_host (Waveshare) with midi2_host_featherSaulo Veríssimo
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.
2026-05-12example: add MIDI 2.0 Host example with display (midi2_host)Saulo Veríssimo
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
2026-05-12feat: add MIDI 2.0 Device class driver (USB-MIDI 2.0)Saulo Veríssimo
Add native USB-MIDI 2.0 Device class driver to TinyUSB. Implements the USB-MIDI 2.0 specification with both Alt Setting 0 (MIDI 1.0 fallback) and Alt Setting 1 (UMP native) descriptor support. Driver features: - UMP (Universal MIDI Packet) read/write with atomic message framing - Protocol negotiation: Endpoint Discovery, Config Request/Notify, Function Block Discovery (embedded in driver) - Group Terminal Block descriptor via GET_DESCRIPTOR - Alt Setting switch handler with endpoint re-arm - Static allocation, no dynamic memory, ISR-safe Build system: - Register midi2d_* in usbd.c driver table - Add TUD_MIDI2_DESCRIPTOR macros to usbd.h - Add config defaults (CFG_TUD_MIDI2_*) to tusb_option.h - Add midi2_ump_word_count() to midi.h (shared by Device and Host) - Add midi2_device.c/h to family.cmake and CMakeLists.txt - Add midi2_device.h include to tusb.h All changes guarded by #if CFG_TUD_MIDI2 (default 0). Zero impact on existing drivers and examples. Tested: Raspberry Pi Pico (RP2040), Linux ALSA, Windows MIDI Services
