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.

rp2040: RP2350/pico2 ETM trace over fly-wired MIPI-20

2026-07-24T08:56:14Z

J-Link's built-in RP2350 script owns the whole chip-side path (component map is not ROM-table-discoverable; a custom JLinkScript replaces the built-in one and kills pin trace), re-arming at every resume - firmware does no trace setup. TRACE_ETM builds pin clk_sys to 48 MHz from crt0 (fly-wire seating-proof; the port is DDR at clk_sys/2 and the J-Trace PRO V2 cliff sits just above 40 MHz TRACECLK - SEGGER requires V3.0+ for this chip), clear TIMER0/1 DBGPAUSE (default freezes the us-timer while any core is debug-halted and sleep_ms spins forever), and run the UART console TX-only (GPIO1 = default UART0 RX = TRACECLK).

fix(rp2040): make stdio_rtt_init static

2026-07-24T07:55:59Z

LOGGER=rtt builds of any rp2040 example fail with -Werror=missing-prototypes (stdio_rtt_init has no prototype and is only called from family.c). Found by building cdc_msc -DLOG=2 -DLOGGER=rtt for raspberry_pi_pico.
