An nRF UARTE receiver starts at boot and never stops. The GPS UART
suspend in standby/off was limited to boards with GPS power control,
because suspending into a module that is still streaming NMEA could
hang the main thread waiting for RXTO (RAK3401, 1.16.6). Patch 0010
bounds that wait (4 ms, then the peripheral is disabled and the events
cleared) and resume re-arms from a clean state, so gps_power.cpp drops
the requirement: gat562_30s, muziworks_r1neo, rak3401_1watt, rak4631
and xiao_nrf54l15 now release the UART too.
Stress-tested with a temporary hook on the T1000-E, GPS streaming NMEA
at 115200: 900 suspend/resume cycles at random points of the stream,
no failure, slowest suspend 640 us (the bounded fallback never ran),
NMEA callbacks back at 1 Hz after every round.
xiao_nrf54l15 gets an optional gnss-nmea-generic on uart21 (D6/D7,
9600), as the RAK4631 and Heltec V3 have: a user-fitted GPS works on
the release image, and with nothing fitted the port, enabled upstream
and unused until now, no longer keeps its receiver armed. On the bench
unit: boots, GPS acquiring, 10 x gps off/on and two reboots clean.
Builds: rak4631 repeater and companion, rak3401_1watt, gat562_30s,
muziworks_r1neo, xiao_nrf54l15 repeater and companion.
- LoRaRadioBase -> LoRaRadio (final); SX126x/SX127x/LR1110/LR2021Radio
replaced by const LoRaRadioOps tables (radio_ops_<family>.cpp), one
linked per build; mains construct the radio in one line
- lr20xx: vendored Semtech SDK + HAL moved beside the driver (no app-tree
sources), DIO1 handler split (CCN 52 -> 10), zc_lora_timing.h adopted,
dead exports removed, header rewritten, comment diet (image-identical)
- semtech,lr2021 uses the lr1110 property names (irq-gpios, tcxo-voltage,
rfsw-*), compiled config byte-identical
- correct the stale "LR2021 is not CAD-probed" claim
- boards/**/zephcore.yml: one manifest per board/preset (release roles,
variants, catalog metadata, capabilities); scripts/board_manifest.py
validates and serves them to build.sh, gen_provider_catalog.py and
docs/supported_boards.md
- cmake/zephcore_board.cmake: board dir -> platform, shared by app and
sysbuild; removes the board-name regex lists and 7 separate globs
- conf chain: exact-name role/debug classification checked against
Kconfig, idempotent across non-pristine reconfigures, version string
single-sourced (BT DIS rev generated), day-granular build epoch
- Doom easter egg: Kconfig default for the wio_tracker_l1 companion
instead of a build.sh-only flag
- catalog: maker for the LR2021 EVK (KeyError before); CI installs PyYAML
- user -DEXTRA_DTC_OVERLAY_FILE overlays now take precedence over derived overlays
Verified: identical .config, DTS and source lists for 97 board/role
configs; identical images for 4 reference builds; identical build.sh
command/artifact set and catalog content.
