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.

stm32h7: tune stm32h743eval ozone trace reference

+100 ps sample timing at 400 MHz core / 50 MHz TRACECLK (PLL1R-fixed), width 4. Startup-burst overflow at 400 MHz is expected; board.h documents the PLLN reduction for overflow-free capture.

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)
