This is the Linux BSP (Board Support Package) and the development environment for the STM32MP2 Evaluation Board, release 4.3.1.

The BSP provides a software development environment for evaluation and development of Linux on the STM32MP2 microcontroller variants (with up to 2 Cortex-A35 processor cores running up to the 1500MHz) using the ST’s STM32MP257F-EV1 Starter Kit as a hardware platform.

2. Supported Features

The following list provides a summary of the features and capabilities of this release of the STM32MP2 EV1 BSP:

  • Linux:

3. Known Problems and Limitations

This section lists known problems and limitations of this release:

  1. The target auto-boot feature does not work with picocom as that terminal application causes the U-Boot auto-boot count-down to be interrupted, effectively rendering the auto-boot feature not working.
    Workaround: The minicom terminal can be used as an alternative terminal application, which doesn’t cause the issue.
    ID: STM32MP2-5.
