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.

same7x: ETM trace support for same70_xplained

2026-07-24T08:56:14Z

J403 (bottom-side Cortex Debug+ETM footprint, header required): TRACECLK=PD8 peripheral D, TRACED0-3=PD4-7 peripheral C. TRACE_ETM builds hold the KSZ8081 PHY in reset (PD4-7 are its RMII receive outputs and it drives against the trace stream), clock the TPIU from PCK3 (MCK/2) and mux the pins; the ozone reference starts PCK3 in the post-reset/download hooks - TPIU programming while PCK3 is stopped is silently lost. Width-1 validated at the stock 300 MHz core; width 4 blocked on a dead D1 line (suspect probe channel, h743eval crosscheck pending).

refactor family.cmake: rename add_board_target() to family_add_board() and move it to family_configure_common()

2025-10-22T19:23:20Z

also move startup and linker from board target to actual exe
