rusb2: EP0 OUT reliability, HS UTMI PHY power-up, FS-only build support

2026-07-13T08:30:44Z

- EP0 OUT: park a back-to-back data-stage packet the DCP accepted before PID could go NAK and deliver it into the next armed chunk; flow-control the single-buffer control pipe between chunks (usbtest ctrl_out corruption); discard a packet parked while an OUT pipe was halted so BOT reset recovery's fresh CBW read can't receive stale WRITE data - HS UTMI PHY power-up per the FSP sequence, shared by dcd/hcd: CLKSEL programmed from the board XTAL (EK-RA8M1 runs 20 MHz; the 24 MHz reset default never locks) while DIRPD holds the PHY down, then timed release - hw/bsp(ra8m1_ek): fix U60CK divider macro - BSP_CFG_U60CK_DIV used the generic USB_CLOCK_DIV_8 encoding (7), which USB60CKDIVCR rejects, leaving the USBHS link domain at 480 MHz; the USB60-specific BSP_CLOCKS_USB60_CLOCK_DIV_8 (4) sticks and yields the required 60 MHz from PLL1P - support FS-only builds on the high-speed port: gate SYSCFG.HSE on TUD_OPT_HIGH_SPEED (RHPORT_DEVICE_SPEED=OPT_MODE_FULL_SPEED was a silent no-op) and always compile both hwfifo access widths - the FIFO width belongs to the module, not the link speed (FS builds corrupted odd-length tails: 16-bit access against MBW-32) - iso activate: reset stale pipe bookkeeping so a BRDY firing before the class re-arms can't replay a pre-SET_INTERFACE transfer; write PIPEBUF after PIPESEL selects the pipe (PIPESEL-windowed register) - clear-halt: re-assert BUF on a still-armed OUT pipe (usbtest case 29) - bound the D0FIFO ready spin so an undrained double-buffered IN pipe can't freeze the stack with the IRQ masked - usbtest example: cap interrupt mps at 64 on RUSB2 high speed (pipes 6-9 have a fixed 64-byte buffer, RA6M5 UM 29.1) Verified: usbtest 30/30 on ra6m5_ek (HS), ra4m1_ek (FS) and ra8m1_ek (FS-forced build on the HS port).

remove IAR toolchain support from make build system

2026-04-06T04:17:34Z

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. Co-Authored-By: Claude Opus 4.6 (1M context)

make board_uart_read()/write() return -1 when unimplemented for consistency across all families

2026-04-04T14:32:39Z

replace board_millis() with tusb_time_millis_api()

bsp: Disable SysTick ISR if FreeRTOS is enabled

2025-11-25T15:30:32Z

refactor family.cmake: rename add_board_target() to family_add_board() and move it to family_configure_common()

2025-10-22T19:23:20Z

also move startup and linker from board target to actual exe

fix lots of warnings for missing-prototypes for irqhandler

2025-10-14T16:02:32Z

cmake remove EXAMPLE-tinyusb target as library

2025-01-25T09:08:40Z

add cmake RTOS=zephyr (default noos) for zephyr build

2025-01-24T08:06:05Z

- change to use CMAKE_SYSTEM_CPU to prevent CMAKE_SYSTEM_PROCESSOR conflict with zephyr

2025-01-22T15:31:08Z

- change tinyusb CMakeLists.txt to function tinyusb_target_add() instead of defining tinyusb lib target
