address #3787 Codex round 2: board-gate PHY resets, session robustness

2026-07-24T14:30:42Z

The board-specific PHY-reset nets move behind a board.h opt-in (TRACE_ETM_QUIET_ENET_PHY on same70_xplained and mimxrt1170_evkb) so other boards of those families cannot inherit a foreign GPIO write; the chip-level trace pin muxes stay family-wide by design (same pattern as stm32h7). same70 reference: width 1 is the validated default until the J403.16 rework, and the hooks now wait (bounded) for PCKRDY3 before Ozone arms trace. ra8m1 reference caches the boot ROM in AfterTargetConnect so --attach sessions decode ROM execution too. etm_capture rejects an unexpanded CMake JLINK_DEVICE with a clear error; PIO-USB + TRACE_ETM on RP2350 is now a compile error (48 MHz trace clock is too slow for PIO-USB and a runtime switch would desync the stream); etm_profile keeps same-named statics from different modules as distinct rows. Build-verified: same70_xplained, mimxrt1170_evkb, raspberry_pi_pico2.

rp2040: RP2350/pico2 ETM trace over fly-wired MIPI-20

2026-07-24T08:56:14Z

J-Link's built-in RP2350 script owns the whole chip-side path (component map is not ROM-table-discoverable; a custom JLinkScript replaces the built-in one and kills pin trace), re-arming at every resume - firmware does no trace setup. TRACE_ETM builds pin clk_sys to 48 MHz from crt0 (fly-wire seating-proof; the port is DDR at clk_sys/2 and the J-Trace PRO V2 cliff sits just above 40 MHz TRACECLK - SEGGER requires V3.0+ for this chip), clear TIMER0/1 DBGPAUSE (default freezes the us-timer while any core is debug-halted and sleep_ms spins forever), and run the UART console TX-only (GPIO1 = default UART0 RX = TRACECLK).

fix(rp2040): make stdio_rtt_init static

2026-07-24T07:55:59Z

LOGGER=rtt builds of any rp2040 example fail with -Werror=missing-prototypes (stdio_rtt_init has no prototype and is only called from family.c). Found by building cdc_msc -DLOG=2 -DLOGGER=rtt for raspberry_pi_pico.

refactor: replace midi2_host (Waveshare) with midi2_host_feather

2026-05-12T14:07:45Z

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.

example: add MIDI 2.0 Host example with display (midi2_host)

2026-05-12T14:07:44Z

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

feat: add MIDI 2.0 Device class driver (USB-MIDI 2.0)

2026-05-12T14:07:44Z

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
