Linux

Here are the installation commands for a few Linux distributions.

Packages

  • Ubuntu 18.04 or newer / Debian stretch or newer

NOTEgdb-multiarch is the GDB command you'll use to debug your ARMCortex-M programs

  1. sudo apt install gdb-multiarch openocd qemu-system-arm
  • Ubuntu 14.04 and 16.04

NOTEarm-none-eabi-gdb is the GDB command you'll use to debug your ARMCortex-M programs

  1. sudo apt install gdb-arm-none-eabi openocd qemu-system-arm
  • Fedora 27 or newer

NOTEarm-none-eabi-gdb is the GDB command you'll use to debug your ARMCortex-M programs

  1. sudo dnf install arm-none-eabi-gdb openocd qemu-system-arm
  • Arch Linux

NOTEarm-none-eabi-gdb is the GDB command you'll use to debug ARMCortex-M programs

  1. sudo pacman -S arm-none-eabi-gdb qemu-arch-extra openocd

udev rules

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

Create the file /etc/udev/rules.d/70-st-link.rules with the contents shown below.

  1. # STM32F3DISCOVERY rev A/B - ST-LINK/V2
  2. ATTRS{idVendor}=="0483", ATTRS{idProduct}=="3748", TAG+="uaccess"
  3. # STM32F3DISCOVERY rev C+ - ST-LINK/V2-1
  4. ATTRS{idVendor}=="0483", ATTRS{idProduct}=="374b", TAG+="uaccess"

Then reload all the udev rules with:

  1. 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 this command:

  1. lsusb

Which should show something like

  1. (..)
  2. Bus001Device018: ID 0483:374bSTMicroelectronics ST-LINK/V2.1
  3. (..)

Take note of the bus and device numbers. Use those numbers to create a path like/dev/bus/usb/<bus>/<device>. Then use this path like so:

  1. ls -l /dev/bus/usb/001/018
  1. crw-------+1 root root 189,17Sep1312:34/dev/bus/usb/001/018
  1. getfacl /dev/bus/usb/001/018| grep user
  1. user::rw-
  2. user:you:rw-

The + appended to permissions indicates the existence of an extendedpermission. The getfacl command tells the user you can make use ofthis device.

Now, go to the next section.
