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.
address #3787 reviews: bsp fixes, script hardening, board-note accuracy2026-07-24T11:38:40Zhathachthach@tinyusb.org2026-07-24T11:38:40Zurn:sha1:e65368ea16975710f029f7ff7e2089b9ea90186d
Bot findings (Copilot/Codex): no-op board_trace_pinmux stubs for
lpcxpresso18s37/43s67 (TRACE_ETM otherwise broke their build), SAME70
ID_PIOD clock enable, capture-script duplicate BeforeTargetConnect on the
RA references, profile-script support for --no-timestamps itraces.
Deep review (whole branch): same70_xplained board row + caveat restored,
stale pico2 72 MHz claim corrected to the shipped 48, explicit
SetTracePortWidth(4) in the three references that relied on Ozone's
default, coverage-cell guard, median-based SysTick calibration, dead
session flag removed, stale RA8M1 divider comment fixed (0x02 = /4 is the
validated chip max) and the debugger guard indented.
EVKB bench findings: only R1884/D3 remains open (D1/D2 meter-verified);
RT1176 trace width is 1 or 4 only - J-Link arms the CSSYS TPIU and its
own sampler at 4-bit for any width>=2 request; a powered MCU-Link USB
breaks the external probe even with JP4 shorted.
same7x: ETM trace support for same70_xplained2026-07-24T08:56:14Zhathachthach@tinyusb.org2026-07-24T08:28:54Zurn:sha1:2a2d5f65ad61dc43d20ff479db9a27510592b50c
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).
