Description

STM32 ST-LINK Utility (STSW-LINK004) is a

full-featured software interface for programming

STM32 microcontrollers.

It provides an easy-to-use and efficient

environment for reading, writing and verifying a

memory device.

The tool offers a wide range of features to

program STM32 internal memories (Flash, RAM,

OTP and others), external memories, to verify the

programming content (checksum, verify during

and after programming, compare with file) and to

automate STM32 programming.

STM32 ST-LINK Utility is delivered as a graphical

user interface (GUI) with a command line

interface (CLI).
