Release Notes 3.0.1 Print



This is the Linux BSP (Board Support Package) and the software development environment for the STMicroelectronics STM32H753I-EVAL Evaluation board, release 3.0.1.

The BSP provides a software development environment for evaluation and development of Linux (uClinux) on the Cortex-M7 processor core of the STM32H7 microcontroller using the STM32H753I-EVAL Evaluation board as a hardware platform.

Supported Features

The following list provides a summary of the features and capabilities of this release of the STM32H7 BSP:

  • Linux:
    • Kernel v.6.1.28;
    • Serial Linux console;
    • Ethernet device driver and Linux TCP/IP networking (ping, NFS, Telnet, FTP, NTPD, etc);
    • Clock driver;
    • pinctrl driver;
    • MMC/SD driver;
    • I2C bus driver;

    • Device driver for SD Card;
    • Environment variables allowing customization of a unit;
    • Autoboot feature, allowing boot of OS images from the SD Card or other storage with no operator intervention;
    • Persistent environment in the SD Card for customization of target operation;
    • Sophisticated command interface for maintenance and development of the target.
  • Development environment:
    • Linux-hosted cross-development environment;
    • 11.3.0 GNU toolchain is used for development of user-space applications;
    • ELF / dynamic linking supported;
    • Hardware FPU enabled in the toolchain and kernel;
    • mkimage tool used by the Linux kernel build process to create a bootable Linux image.
