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.

imxrt: TRACE_ETM for RT1011 and RT1176, validate both boards

2026-07-24T08:56:14Z

metro_m7_1011 (custom ETM-header rework): 500 MHz core, 66 MHz TRACECLK width 4, +50 ps; trace_etm_init ungates the 132 MHz trace root that BOARD_BootClockRUN leaves gated. mimxrt1170_evkb: 996 MHz CM7 at width 1, CSTRACE pinned to 50 MHz (stock 132 corrupts - the Ethernet PHY loads the CLK net) and the CM7 platform trace-funnel port enabled in firmware: J-Link does not program that funnel and everything reads register-perfect yet silent without it. FlexSPI boot needs the committed SP/PC hooks; D1-D3 stay dead pending the R1882-R1884 continuity check (width-4 TODO).

migrate imxrt to use new mcux-devices-rt

Move BOARD_ConfigMPU into board specific init

2025-09-12T12:06:57Z

Signed-off-by: HiFiPhile

imxrt: disable BOARD_ConfigMPU() since it cause issue with imxrt1060/64. Update imxrt configtool forr some board to get uart pin init.

- 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

embed metadata to family.c and board.h to generate supported boards doc

enable CFG_TUD/THU_MEM_DCACHE_ENABLE for imxrt with M7 by default

2024-12-17T13:53:50Z

mimxrt1170_evkb: add M4 build support.
