STM32DDRFW-UTIL features the DDR_Tool full source code to run basic, intensive, or stress DDR tests. It contains a readme file that details how to customize a project configuration and run the DDR tests.

STM32DDRFW-UTIL is the firmware used to initialize DDR and perform DDR tests. This document describes: the Software Architecture and Design of STM32DDRFW-UTIL. how to use the STM32DDRFW-UTIL firmware package for DDR configuration and test on STM32MP1 and STM32MP2 Series MPUs.

4Mbps的WAV文件大概是96K/24bit/2的规格。 STM32的内部总线是可以承受的。 这样的东西用STM32做出来毫无难度。 不过，STM32F1/2/3/4系列还没有DDR接口。 使用标准DDR SDRAM，如果不由FPGA转接，断无可能。 用SDRAM，密度太低。

For the 32-bit LPDDR4 interface, one 32-bit LPDDR4 is used in point-to-point connection. With this configuration, it can drive up to 4 Gbyte memory. For the 32-bit DDR3L/4 interface, two 16-bit DDR3L/4 are used in fly-by topology.

Configuring the DDR subsystem is done by programming multiple settings to the DDR controller (DDRCTRL), the PHY (DDRPHYC), and SDRAM mode registers. These settings are determined according to system parameters such as DDR type, density, topology, frequency, and SDRAM JEDEC parameters.

This article explains how to configure the DDRCTRL and DDRPHYC internal peripherals from the first stage bootloader.

Aug 4, 2022 · About how to connect the board and run the DDR test Suite I found a roughly simple way: Start by downloading this repo GitHub - STMicroelectronics/STM32DDRFW-UTIL: DDRFW-UTIL tool repository

Jul 14, 2021 · I am trying to verify my build environment by building the U-boot code samples to be able to run the DDR Tuning tests.

Mar 26, 2023 · 本文档描述在 STM32MP1 系列 MPU 产品上配置 DDR 子系统（DDRSS）所需的流程和步骤。 设定 DDR 控制器（DDRCTRL）、PHY 接口（DDRPHYC）和 SDRAM 模式寄存器的多个参数以及设置完成 DDRSS 配置。 根据 DDR 类型、DDR 大小、DRAM 拓扑、运行时间频率和 SDRAM 器件数据手册参数确定这些参数。 所有这些参数必须在初始化序列期间设定。 STM32CubeMX DDR 测试套件使用直观的面板和菜单隐藏了与确定正确参数和初始化启动相关 …
