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.

address #3787 reviews: bsp fixes, script hardening, board-note accuracy

2026-07-24T11:38:40Z

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.

imxrt: hold EVKB Ethernet PHY in reset while tracing, 50 MHz trace pin

2026-07-24T09:20:13Z

Fresh bring-up pass on mimxrt1170_evkb: holding the 100M RTL8201 in reset (ENET_RST_B = GPIO_LPSR_04) stops its RMII lines driving against the shared trace pads and doubles the clean trace-pin rate to 50 MHz (100 MHz CSTRACE root; 133 MHz root is marginal, stock 132 corrupts). Validated 3x 8 s TinyUSB captures at 11.46M fetches. D1-D3 remain silent in every configuration - the welded R1882-R1884 are electrically open; reflow is the remaining step to width 4. Board notes gain JP4 (must be shorted for an external probe on J58).

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).

remove IAR toolchain support from make build system

2026-04-06T04:17:34Z

IAR is only supported with CMake. Remove all IAR-specific references from the Make build system including toolchain files, SRC_S_IAR, LD_FILE_IAR variables, and IAR toolchain detection. Also fix GET_SECTOR_COUNT truncation in msc_file_explorer and broken formatting in stm32f7 board_uart_write. Co-Authored-By: Claude Opus 4.6 (1M context)
