ST-LINK Drivers And Firmware

This page covers the adapter being recognized by the operating system.

Platform-specific startup instructions live in the platform READMEs.

Windows

Check Device Manager.

The adapter should:

  • appear when plugged in;
  • disappear when unplugged;
  • not show a yellow warning icon.

If it does not appear, try another USB cable or USB port first. Avoid charge-only cables.

Linux

Check USB visibility:

lsusb

If OpenOCD cannot access the adapter as a normal user, install the OpenOCD udev rules from the Linux package folder.

macOS

Use System Information > USB, or:

system_profiler SPUSBDataType

The adapter must appear as a USB device before x3utils can use it.

Firmware Updates

Genuine ST-LINK adapters may support firmware updates through official ST tools.

Clone adapters may not support firmware updates, may report strange versions, or may have missing reset behavior.

Do not update adapter firmware unless you understand the tool you are using.
