stm32h5: TRACE_ETM support and stm32h563nucleo reference

2026-07-24T08:56:14Z

H5 hangs its debug AP if trace CoreSight is touched unclocked (recover = power-cycle): the reference's AfterTargetConnect clocks the DBGMCU trace domain but defers IOEN to firmware, or the mid-boot clock switch desyncs the decoder. Stock solder bridges make the CN5 path marginal: validated config is 100 MHz core, width 1, +5 ns (board.h selects the reduced clock for TRACE_ETM builds); width 4 / 250 MHz retest waits on SB removal.

bsp/stm32h5: add missing IAR linker script for stm32h533

2026-07-15T13:13:55Z

stm32h533nucleo could never link with IAR: family.cmake points LD_FILE_IAR at linker/stm32h533xx_flash.icf, which did not exist (every sibling H5 variant has one). Surfaced by CircleCI's one-random job picking stm32h533nucleo+IAR (Fatal error[Lc002]). H533 and H523 have identical memory maps (512K flash / 272K RAM; their GCC .ld files differ only in a comment), so the icf is a copy of the H523 one.

fix stm32h5 hard fault when reading UID with ICACHE enabled

2026-04-09T18:16:22Z

On STM32H5, reading UID_BASE with ICACHE enabled causes a hard fault (ST errata). Cache the unique ID at the very start of board_init(), before any user code has a chance to enable ICACHE. Closes: https://github.com/hathach/tinyusb/discussions/3588 Co-Authored-By: Claude Opus 4.6 (1M context)

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)
