sudo touch /etc/udev/rules.d/lesĪdd the following lines into the file /etc/udev/rules.d/les which we just created in the line above: KERNEL='tty*', MODE='0666' Now that we OpenOCD installed, let's allow unprivileged users to run OpenOCD by adding some udev rules in a file called les. OpenOCD is available in the AUR (for Arch Linux users) but I will build it from source here, as not everyone is using Arch. pacman -S gcc make arm-none-eabi-gcc arm-none-eabi-newlib arm-none-eabi-gdb libusb libtool pkg-config autoconf automake git which These packages should be available on most distros (Using Arch as an example). I am also demonstrating the installation and setup of this software on Arch Linux, again this should not be a problem if you are using a different flavor of Linux, all you have to do is find the packages using your package manager.If you are using a different board, this tutorial can still provide all the steps needed to do the same on your board, you will just have to make some small changes to make sure you are targeting your board. In this tutorial I will be using the STM32L476 Nucleo-64 board by STMicroelectronics as the target board.We will then learn a bit about an open source tool called OpenOCD which will allow us to interactively debug our code using the GNU debugger (gdb) as well as flash our code directly onto our board. We will be creating a Makefile that will cross compile our code to target the STM32L4xx Cortex-M4 boards. This is a more detailed and minimalist version of the tutorial I posted last summer.
