nrf5x: fix hfclk_running() for nrfx v2.0.0

2026-07-10T13:17:38Z

nrf_clock_is_running() was added in nrfx 2.1.0 (MDK 8.30.2), but the version autodetect puts 2.0.0 (MDK 8.29.0) in the v2 bucket, so hfclk_running() fails to compile on that nrfx. Route v2 through nrf_clock_hf_is_running(), which all of 2.x provides. Co-Authored-By: Claude Opus 4.8 (1M context)

dcd(nrf5x): errata 199 DMA workaround + iso alloc/activate

2026-07-09T16:38:28Z

USBD drops tasks during EasyDMA without the 0x40027C1C latch (anomaly 199); matches the nrfx reference driver. Co-Authored-By: Claude Fable 5 Claude-Session: https://claude.ai/code/session_01HeF2gZ1M7GWkz6Av4BpKPg

* license: use SPDX identifiers for src/ headers Replace the full ~20-line MIT license boilerplate on every src/ file with a two-line SPDX tag (SPDX-FileCopyrightText + SPDX-License-Identifier), following the REUSE convention used by CircuitPython and the Linux kernel. Removes ~3500 lines of duplicated boilerplate.

nrf5x: request HFCLK in USB_EVT_READY to fix post-SoftDevice deadlock

2026-05-08T14:27:53Z

USB_EVT_DETECTED runs hfclk_enable() which, when SoftDevice is not yet enabled, starts HFXO via direct CLOCK register access. 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. With the fix, USB enumerates and BLE advertises as expected.

Merge remote-tracking branch 'tinyusb/master' into copilot/fix-dcd-edpt-xfer-issue

2025-11-19T21:05:07Z

Signed-off-by: HiFiPhile

make TUP_DCD_EDPT_ISO_ALLOC i.e dcd_edpt_iso_alloc()/dcd_edpt_iso_activate() as default driver implementation. dcd_edpt_close() is deprecated and will be removed from all driver in the future.
