Linux

Here are the installation commands for a few Linux distributions.

Packages

• Ubuntu 18.04 or newer / Debian stretch or newer

NOTE gdb-multiarch is the GDB command you'll use to debug your ARM Cortex-M programs

$ sudo apt-get install \
  gdb-multiarch \
  openocd \
  qemu-system-arm

• Ubuntu 14.04 and 16.04

NOTE arm-none-eabi-gdb is the GDB command you'll use to debug your ARM Cortex-M programs

$ sudo apt-get install \
  gdb-arm-none-eabi \
  openocd \
  qemu-system-arm

• Fedora 27 or newer

NOTE arm-none-eabi-gdb is the GDB command you'll use to debug your ARM Cortex-M programs

$ sudo dnf install \
  arm-none-eabi-gdb \
  openocd \
  qemu-system-arm

• Arch Linux

NOTE arm-none-eabi-gdb is the GDB command you'll use to debug ARM Cortex-M programs

$ sudo pacman -S \
  arm-none-eabi-gdb \
  qemu-arch-extra

$ # install openocd from the AUR -- https://aur.archlinux.org/packages/openocd/

udev rules

This rule lets you use OpenOCD with the Discovery board without root privilege.

Create this file in /etc/udev/rules.d with the contents shown below.

$ cat /etc/udev/rules.d/99-st-link.rules

# STM32F3DISCOVERY rev A/B - ST-LINK/V2
ATTRS{idVendor}=="0483", ATTRS{idProduct}=="3748", MODE:="0666"

# STM32F3DISCOVERY rev C+ - ST-LINK/V2-1
ATTRS{idVendor}=="0483", ATTRS{idProduct}=="374b", MODE:="0666"

Then reload all the udev rules with:

$ sudo udevadm control --reload-rules

If you had the board plugged to your laptop, unplug it and then plug it again.

You can check the permissions by running these commands:

$ lsusb
(..)
Bus 001 Device 018: ID 0483:374b STMicroelectronics ST-LINK/V2.1
(..)

Take note of the bus and device numbers. Use those numbers in the following command:

$ # the format of the path is /dev/bus/usb/<bus>/<device>
$ ls -l /dev/bus/usb/001/018
crw-rw-rw- 1 root root 189, 17 Sep 13 12:34 /dev/bus/usb/001/018

The permissions should be crw-rw-rw-; this indicates that all users can make use of this device.
