Installation instructions for STLINK/v1 driver

When connecting to the STLINK/v1 on macOS via USB, the system claims the programmer as a SCSI device. Thus libusb is not able to initialise and establish a connection to it. To solve this issue Marco Cassinerio (marco.cassinerio@gmail.com) has created a so called "codeless driver" which claims the device. It is of higher priority then the default apple mass storage driver, what allows the device to be accessed through libusb.

To make use of this alternative approach one needs to go through the following steps:

  1. Configure System Integrity Protection (SIP)

The above system security setting introduced by Apple with OS X El Capitan (10.11) in 2015 is active per default and prevents the operating system amongst other things to load unsigned Kernel Extension Modules (kext). Thus the STLINK/v1 driver supplied with the tools, which installs as a kext, remains not functional, until SIP is fully deactivated. Without SIP-deactivation, st-util would fail to detect a STLINK/v1 device later on.

In order to deactivate SIP, boot into the recovery mode and run csrutil disable in a terminal console window.

  1. Reboot the system.

  2. Install the macOS Kernel Extension (kext) (ST-Link-v1 driver):

  • Open a terminal console and navigate to this subdirectory /stlinkv1_macos_driver
  • Use the command sudo sh ./install.sh to install the appropiate kext for your system version. This should result in the following output:
Requesting load of /Library/Extensions/stlink_shield.kext.
/Library/Extensions/stlink_shield.kext loaded successfully (or already loaded).

  1. Reboot the system.

  2. Verify correct detection of the STLINK/v1 device with the following input: st-util -1 You should then see a similar output like in this example:
