STR8 STM32MP15 Implementation

This course describes the STM32MP15x SoC

  • This course details the hardware implementation of the STM32MP15x SoC
  • The course focuses on the boot sequence, the clocking and the power management strategies
  • The course explains all parameters that affect the performance of the system in order to easily perform the final tuning
  • An overview of the Cortex-A7MP core helps to understand issues caused by MMU, cache and snooping
  • An overview of the Cortex-M4F with MPU is included to understand the microcontroller side of the STM32MP15 implementation
  • To become more familiar with the synchronization features of the STM32MP15x implementation labs are proposed
  • Note that this course has been designed from the architecture of STM32MP15x-series devices, the STM32MP157C
  • The peripherals overview presented in this course can be detailed upon request (STR9 - STM32 Peripherals course)
