STM32 bootloader

Flashing via USART Most STM32 devices have an on-board (first-level) boot-loader (see Table1 of AN2606 for an overview of supported devices). The boot-loader allows developers to flash MCU’s internal ROM memory via SPI, CAN, USB, I2C etc. but for our project we want to connect via USART to the STM32 MCU. The USART protocol that is […]


Embedded device boot

Eventually an embedded device’s micro controller or processor is expected to execute the designed-for-the-purpose software. But before that happens, some vendor specific voodoo is required. Only then, it understands it should run your code, which is located at the place where you put it. First-level boot-loader Most modern micro-controllers nowadays have first-level boot-loaders. They initialize […]
