STM32 microcontroller development guide

A technical series outlines the process of developing code for STM32 microcontrollers using open-source tools on a Linux environment. The guide covers hardware setups, such as the STM32F3DISCOVERY board, and the necessity of using a cross-compiler to emit instructions for target ARM hardware.

The documentation explains the microcontroller power-on sequence, noting that the device reads the states of the BOOT0 and BOOT1 pins to determine its boot mode. Supported modes typically include main flash memory for standard code execution, system memory for using the manufacturer-provided bootloader via peripherals like USB or UART, and embedded SRAM for temporary bootloaders.
