The installation will create a shortcut for the STM32 Flash Loader Demonstrator. How to Use the Flash Loader Tool to Program an STM32 Hardware Requirements STM32 Board (e.g., STM32F103 BluePill) USB-to-UART Converter (3.3V) Wires for UART connection (TX, RX, GND) Step-by-Step Programming Process Prepare the Connection: Connect USB Converter TX to STM32 RX (PA10 for USART1). Connect USB Converter RX to STM32 TX (PA9 for USART1). Connect GND . Connect 3.3V . Enter Bootloader Mode: Connect the BOOT0 pin to 3.3V (High). Reset the MCU (connect NRST to GND then release). Run the Tool: : Version 7
: Power off the phone. Hold the designated Boot Key (often the '1' and '3' keys together for models like the E2252) while connecting the USB cable to the PC. Connect USB Converter RX to STM32 TX (PA9 for USART1)
