## Summary STM32H7S3L8 renamed stm32h7 D1 domain AHB prescaler from HPRE to BMPRE bus mantrix clock prescaler (which generates AXI peripheral clock from sys-cpu-ck). See 8.7.8 of ST RM0433 for STM32H7 HPRE and 7.8.8 of ST RM0477 for STM32H7RSxx BMPRE definitions. Change field name in stm32h7rsxx_rcc.h and usage in stm32h7rsxx_rcc.c, as well as nucleo-h7s3l8 and stm32h7s8-dk board.h files. ## Impact - User experience: No adaptation required. This fix does not change generated code. - Build: No impact. - Hardware: Affects stm32h7rs based-boards (nucleo-h7s3l8 and stm32h7s8-dk). - Documentation: No impact. - Security: No impact. - Compatibility: Backward compatible ## Testing Build Host: - OS: Ubuntu 24.04.4 LTS - Compiler: arm-none-eabi-gcc 13.2.1 Target: - Architecture: ARM (STM32H7S3L8) - Board: STM32H7S8-DK and NUCLEO_H7S3L8 - Configuration: Default jumbo-xip and boot-xip for both boards Testing performed: Booted both boards Runtime testing: From nucleo-h7s3l8 console: ``` NuttShell (NSH) NuttX-13.1.0 nsh> uname -a NuttX 13.1.0 846e525657-dirty Oct 26 2026 16:15:42 arm nucleo-h7s3l8 nsh> ``` From stm32h7s3l8-dk console: ``` Bootloader 13.1.0 846e525657-dirty Oct 26 2026 16:02:36 arm stm32h7s8-dk telnetd [6:100] NuttShell (NSH) NuttX-13.1.0 nsh> uname -a NuttX 13.1.0 846e525657-dirty Oct 26 2026 16:02:41 arm stm32h7s8-dk nsh> ``` -- This is an automated message from the Apache Git Service.
