STM32 ST-LINK Utility (STSW-LINK004)

What is STM32 ST-LINK utility?

STM32 ST-LINK Utility, also called STSW-LINK004, is a tool for programming (reading, writing, erasing, option words) of the entire STM32 series of chips. It not only provides a graphical interface (GUI), but also provides a command line interface (CLI).

Compared with ST Visual Programmer (STVP), ST-LINK Utility only supports the download debugger of ST-Link (multiple versions), and the only supported chip is STM32.

Programmable Files

  • Motorola S19
  • Bin file
  • Hex file

Functions

  • Erase, Read, Verify
  • One-time automated Programming (download/write)
  • Provides command line interface (CLI)
  • ST-LINK/V2 firmware upgrade
  • Configuration option byte
  • Compare file to target memory
  • Program\erase and verify external memory
  • Can load, edit and save executable and data files
  • Supports memory and core status views in real-time update mode

How to Use STM32 ST-LINK Utility?

As a programming tool, ST-LINK Utility includes conventional reading, writing (downloading / programming), erasing, option byte programming, etc. In this example, we use STM32F411 to show the details:
