From c9f09d6079cd483737ac15d9add4afac0dc74540 Mon Sep 17 00:00:00 2001 From: Jerzy Kasenberg Date: Mon, 13 Nov 2023 17:37:18 +0100 Subject: [PATCH] Add BSP for nucleo-g491re This adds bsp for ST nucleo-g491re board. This is mostly copy of nucleo-f474 only differences being: - PLL configured to 170MHz (not affecting USB which runs on HSI48) - Linker script freshly generated from STM32CubeIDE (smaller RAM) Signed-off-by: Jerzy Kasenberg --- .../stm32g491nucleo/STM32G491RETX_FLASH.ld | 185 ++++++++++++++++++ .../boards/stm32g491nucleo/board.cmake | 11 ++ hw/bsp/stm32g4/boards/stm32g491nucleo/board.h | 104 ++++++++++ .../stm32g4/boards/stm32g491nucleo/board.mk | 11 ++ 4 files changed, 311 insertions(+) create mode 100644 hw/bsp/stm32g4/boards/stm32g491nucleo/STM32G491RETX_FLASH.ld create mode 100644 hw/bsp/stm32g4/boards/stm32g491nucleo/board.cmake create mode 100644 hw/bsp/stm32g4/boards/stm32g491nucleo/board.h create mode 100644 hw/bsp/stm32g4/boards/stm32g491nucleo/board.mk diff --git a/hw/bsp/stm32g4/boards/stm32g491nucleo/STM32G491RETX_FLASH.ld b/hw/bsp/stm32g4/boards/stm32g491nucleo/STM32G491RETX_FLASH.ld new file mode 100644 index 000000000..f5553a112 --- /dev/null +++ b/hw/bsp/stm32g4/boards/stm32g491nucleo/STM32G491RETX_FLASH.ld @@ -0,0 +1,185 @@ +/* +****************************************************************************** +** +** @file : LinkerScript.ld +** +** @author : Auto-generated by STM32CubeIDE +** +** Abstract : Linker script for NUCLEO-G491RE Board embedding STM32G491RETx Device from stm32g4 series +** 512KBytes FLASH +** 112KBytes RAM +** +** Set heap size, stack size and stack location according +** to application requirements. +** +** Set memory bank area and size if external memory is used +** +** Target : STMicroelectronics STM32 +** +** Distribution: The file is distributed as is, without any warranty +** of any kind. +** +****************************************************************************** +** @attention +** +** Copyright (c) 2023 STMicroelectronics. +** All rights reserved. +** +** This software is licensed under terms that can be found in the LICENSE file +** in the root directory of this software component. +** If no LICENSE file comes with this software, it is provided AS-IS. +** +****************************************************************************** +*/ + +/* Entry Point */ +ENTRY(Reset_Handler) + +/* Highest address of the user mode stack */ +_estack = ORIGIN(RAM) + LENGTH(RAM);
