Purpose

This driver provides a set of functions to manage:

  • LEDs, push-button, Virtual Com Port (VCP), Audio, USB-PD, LCD, camera sensor and external memories access on STM32N6570-DK Kit from STMicroelectronics

Update History

V1.4.1 / 31-July-2026

Main Changes

Fifth maintenance release of board drivers supporting STM32N6570-DK board (MB1939C)

Contents

  • stm32n6570_discovery_xspi update:
    • Fix XSPI_NOR_ResetMemory() to reset the memory in all modes without relying on context, and skip the WIP check during reset.

Known Limitations

  • None

Dependencies

  • ISP library v1.2.1

Notes

stm32n6570_discovery_conf_template.h file must be copied in user application as stm32n6570_discovery_conf.h with optional configuration update

Main Changes

Fourth maintenance release of board drivers supporting STM32N6570-DK board (MB1939C)

Contents

  • stm32n6570_discovery_xspi update:
    • Remove Delay inside DOPI SOPI functions .
    • Adjust CSHT to feat with MX66 Tshsl timing.
    • Fix BSP_XSPI_NOR_LeaveDeepPowerDown() to use ReleasePowerDown.

Known Limitations

  • None

Dependencies

  • ISP library v1.2.1

Notes

stm32n6570_discovery_conf_template.h file must be copied in user application as stm32n6570_discovery_conf.h with optional configuration update
