2026-06-25fix(dwc2_hcd): correct HFIR for Low-Speed devices via internal FS PHYZhang, Zhenjiang
When a Low-Speed device is connected through the internal FS PHY, the effective PHY clock is 6MHz (HCFG_FSLS_PHYCLK_SEL_6MHZ), but phy_clock was incorrectly left at 48. This caused HFIR to be calculated as 47999 (~8ms SOF interval) instead of the correct 5999 (1ms SOF interval), breaking periodic endpoint scheduling. Fixes: LS mouse only receiving first HID report on OTG_HS + FS PHY
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.
