With the default RX FIFO sized equal to one bulk packet, the next bulk IN transfer fails to queue and the driver silently stops receiving. Raising the default to 2x bulk gives single-call apps a full packet of headroom and documents the drain-loop expectation. Reproduced with Akai LPD8 mk1 (VID 09E8 PID 0075) on STM32H753 DWC2 host; fixed with this patch.

After sd_softdevice_enable() takes over CLOCK, HFXO is physically off again and SD's HFCLK reference count is 0. If USB_EVT_READY is fired post-SD (e.g. on nRF52 via Bluefruit's usb_softdevice_post_enable() when the pre-SD nrfx_power READY callback didn't get to run before nrfx_power was uninited), the wait loop 'while (!hfclk_running()) {}' calls sd_clock_hfclk_is_running() which returns false forever -> deadlock that blocks both USB enumeration and any further app code on the calling thread. Call hfclk_enable() right before the wait so HFCLK is requested in whichever context (SD or direct) is current. hfclk_enable() is idempotent. Reproduces reliably with bleuart on Feather nRF52840 Express flashed via JLink: chip wedges in sd_clock_hfclk_is_running SVC, no USB enumeration, no BLE advertising.

(USB-MIDI 2.0) Add native USB-MIDI 2.0 Host class driver to TinyUSB. Implements reactive architecture: enumerate, detect MIDI 2.0 capability, inform application via callbacks. Driver features: - Parse both Alt Setting 0 (MIDI 1.0) and Alt Setting 1 (UMP) - Detect bcdMSC version from descriptor - Auto-select highest protocol (Alt 1 preferred if available) - UMP read/write via endpoint streams - Proper Audio Control interface skip (loop-based, following midi_host.c pattern) - Endpoint open with tuh_edpt_open/tu_edpt_stream_open/clear - usbh_driver_set_config_complete for USBH state machine - Handle Audio Control itf_num in set_config gracefully - 5 weak callback stubs (descriptor, mount, unmount, rx, tx) Build system: - Register midih2_* in usbh.c driver table - Add midi2_host.h include to tusb.h - Add CFG_TUH_MIDI2_LOG_LEVEL to tusb_option.h All changes guarded by #if CFG_TUH_MIDI2 (default 0). Zero impact on existing drivers and examples. Tested: Waveshare RP2350-USB-A (Host) receiving UMP from Raspberry Pi Pico (Device) via PIO-USB, board-to-board --- src/class/midi/midi2_host.c | 502 ++++++++++++++++++++++++++++++++++++++++++++ src/class/midi/midi2_host.h | 99 +++++++++ src/host/usbh.c | 12 ++ 3 files changed, 613 insertions(+) create mode 100644 src/class/midi/midi2_host.c create mode 100644 src/class/midi/midi2_host.h diff --git a/src/class/midi/midi2_host.c b/src/class/midi/midi2_host.c new file mode 100644 index 000000000..beb441b56 --- /dev/null +++ b/src/class/midi/midi2_host.c @@ -0,0 +1,502 @@ +/* + * The MIT License (MIT) + * + * Copyright (c) 2026 Saulo Verissimo + * + * Permission is hereby granted, free of charge, to any person obtaining a copy + * of this software and associated documentation files (the "Software"), to deal + * in the Software without restriction, including without limitation the rights + * to use, copy, modify, merge, publish, distribute, sublicense, and/or sell + * copies of the Software, and to permit persons to whom the Software is + * furnished to do so, subject to the following conditions: + * + * The above copyright notice and this permission notice shall be included in + * all copies or substantial portions of the Software. + * + * THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR + * IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, + * FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.

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. --- examples/host/CMakeLists.txt | 2 +- examples/host/midi2_host/CMakeLists.txt | 38 --- examples/host/midi2_host/Makefile | 27 -- examples/host/midi2_host/src/display.c | 221 -------------- examples/host/midi2_host/src/display.h | 54 ---- examples/host/midi2_host/src/font5x7.h | 107 ------- examples/host/midi2_host/src/main.c | 326 --------------------- examples/host/midi2_host/src/tusb_config.h | 91 ------ .../boards/waveshare_rp2350_usb_a/board.cmake | 2 - .../rp2040/boards/waveshare_rp2350_usb_a/board.h | 49 ---- 10 files changed, 1 insertion(+), 916 deletions(-) delete mode 100644 examples/host/midi2_host/CMakeLists.txt delete mode 100644 examples/host/midi2_host/Makefile delete mode 100644 examples/host/midi2_host/src/display.c delete mode 100644 examples/host/midi2_host/src/display.h delete mode 100644 examples/host/midi2_host/src/font5x7.h delete mode 100644 examples/host/midi2_host/src/main.c delete mode 100644 examples/host/midi2_host/src/tusb_config.h delete mode 100644 hw/bsp/rp2040/boards/waveshare_rp2350_usb_a/board.cmake delete mode 100644 hw/bsp/rp2040/boards/waveshare_rp2350_usb_a/board.h diff --git a/examples/host/CMakeLists.txt b/examples/host/CMakeLists.txt index 7c74e3c73..2cf2c10af 100644 --- a/examples/host/CMakeLists.txt +++ b/examples/host/CMakeLists.txt @@ -13,7 +13,7 @@ set(EXAMPLE_LIST device_info hid_controller midi_rx - midi2_host + midi2_host_feather msc_file_explorer msc_file_explorer_freertos ) diff --git a/examples/host/midi2_host/CMakeLists.txt b/examples/host/midi2_host/CMakeLists.txt deleted file mode 100644 index cd70d122a..000000000 --- a/examples/host/midi2_host/CMakeLists.txt +++ /dev/null @@ -1,38 +0,0 @@ -cmake_minimum_required(VERSION 3.20) - -include(${CMAKE_CURRENT_SOURCE_DIR}/../../../hw/bsp/family_support.cmake) - -project(midi2_host C CXX ASM) - -family_initialize_project(${PROJECT_NAME} ${CMAKE_CURRENT_LIST_DIR}) - -# This example requires PIO-USB and Pico SDK (I2C, SSD1306 display) -if(NOT FAMILY STREQUAL "rp2040") - return() -endif() - -add_executable(${PROJECT_NAME}) - -target_sources(${PROJECT_NAME} PUBLIC - ${CMAKE_CURRENT_SOURCE_DIR}/src/main.c - ${CMAKE_CURRENT_SOURCE_DIR}/src/display.c -) - -target_include_directories(${PROJECT_NAME} PUBLIC - ${CMAKE_CURRENT_SOURCE_DIR}/src -) - -family_configure_host_example(${PROJECT_NAME} noos) - -# Waveshare RP2350-USB-A: PIO-USB on GP12/GP13 -target_compile_definitions(${PROJECT_NAME} PRIVATE - PIO_USB_DP_PIN_DEFAULT=12 -) -target_compile_options(${PROJECT_NAME} PRIVATE - -Wno-type-limits -) - -# SSD1306 display (I2C) -target_link_libraries(${PROJECT_NAME} PUBLIC - hardware_i2c -) diff --git a/examples/host/midi2_host/Makefile b/examples/host/midi2_host/Makefile deleted file mode 100644 index 2b4660516..000000000 --- a/examples/host/midi2_host/Makefile +++ /dev/null @@ -1,27 +0,0 @@ -# This example requires RP2040/RP2350 (PIO-USB, Pico SDK I2C, SSD1306 display) -ifeq (,$(findstring rp2040,$(FAMILY))) -$(info Skipping midi2_host: requires FAMILY=rp2040) -all: - @: -.DEFAULT: - @: -else - -include ../../../hw/bsp/family_support.mk - -INC += \ - src \ - -# Example source -EXAMPLE_SOURCE += \ - src/main.c \ - src/display.c \ - -SRC_C += $(addprefix $(EXAMPLE_PATH)/, $(EXAMPLE_SOURCE)) - -# Suppress pre-existing warning -CFLAGS_GCC += -Wno-type-limits - -include ../../../hw/bsp/family_rules.mk - -endif diff --git a/examples/host/midi2_host/src/display.c b/examples/host/midi2_host/src/display.c deleted file mode 100644 index 4745c2961..000000000 --- a/examples/host/midi2_host/src/display.c +++ /dev/null @@ -1,221 +0,0 @@ -/* - * The MIT License (MIT) - * - * Copyright (c) 2026 Saulo Verissimo - * - * Permission is hereby granted, free of charge, to any person obtaining a copy - * of this software and associated documentation files (the "Software"), to deal - * in the Software without restriction, including without limitation the rights - * to use, copy, modify, merge, publish, distribute, sublicense, and/or sell - * copies of the Software, and to permit persons to whom the Software is - * furnished to do so, subject to the following conditions: - * - * The above copyright notice and this permission notice shall be included in - * all copies or substantial portions of the Software. - * - * THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR - * IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, - * FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.

Build-tested on adafruit_feather_rp2040_usb_host, daisyseed (stm32h7), mimxrt1010_evk, stm32f407disco, raspberry_pi_pico2, b_u585i_iot2a, portenta_c33, stm32h503nucleo, stlinkv3mini, feather_stm32f405.
