samd5x_e5x: ETM trace support for same54_xplained

2026-07-24T08:56:14Z

The populated 20-pin Cortex Debug+ETM header carries 4-bit trace (TRACECLK=PC27, D0-3=PC28/PC26/PC25/PC24, mux H). TRACE_ETM builds mux the pins and enable GCLK channel 47 (GCLK_CM4_TRACE) from GCLK0 - without that gate the port stays silent with pins and TPIU armed. Chip-max 120 MHz core / 60 MHz TRACECLK validated (3x 280M-fetch captures).

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)
