SYNOPSIS
st-info [--probe] [--flash] [--sram] [options]
DESCRIPTION
st-info queries information from STM32 microcontrollers connected via an ST-Link programmer/debugger. It reports device identification details including chip ID, device description, flash memory size, SRAM size, and the programmer's serial number.The tool is useful for verifying hardware connections, identifying unknown STM32 variants, and confirming memory sizes before programming. The --probe option provides a comprehensive summary of all connected devices. It is part of the open-source stlink toolset.
