Step 2 - Compiling, Installing, and Connecting to the UART Demo Program from STM32CubeF4įirst thing's first - unzip the STM32CubeF4 archive in your user's home directory:īefore proceeding any further, let's take a high-level look at how this entire process works. One could run fdisk on this device to see what partitions are available, and then mount the filesystems if there was a need to copy files onto the device's flash. Keep this in mind for later.Ĭoincidentally, it looks like the board also provides a USB Mass Storage device, located at /dev/sdb. Accordingly, the serial path that will be used to connect to this particular board is /dev/ttyACM0. The line I emphasized with the > is the important part - ttyACM0 indicates that whatever just connected over USB has an available serial port. usb 2-2.1: Manufacturer: STMicroelectronics usb 2-2.1: New USB device strings: Mfr=1, Product=2, SerialNumber=3 usb 2-2.1: New USB device found, idVendor=0483, idProduct=374b usb 2-2.1: new full-speed USB device number 9 using uhci_hcd usb 2-2.1: USB disconnect, device number 8 > cdc_acm 2-2.1:1.2: ttyACM0: USB ACM device usb 2-2.1: reset full-speed USB device number 8 using uhci_hcd sd 33:0:0:0: Attached SCSI removable disk sd 33:0:0:0: Assuming drive cache: write through sd 33:0:0:0: Attached scsi generic sg2 type 0 scsi 33:0:0:0: Direct-Access MBED microcontroller 1.0 PQ: 0 ANSI: 2 To find the Nucleo, plug the board into your computer's USB port, and then immediately run dmesg from a terminal. To do this though, you need to know what to look for, as there are many files in /dev. In Linux, everything is a file, which means that you will be able to access the serial connection provided by the Nucleo as a standard device file in /dev. Step 1 - Connecting the Nucleo and Getting the Serial Port Handle Read through the package information here while downloading the software. This archive contains the examples we will use as our basis for the small serial project created with this guide, as well as all of the necessary header files required to compile for the platform. You will also need the STM32CubeF4 archive. Once updated, install each package with sudo apt-get install Just make sure that your repository is up-to-date by running sudo apt-get update sudo apt-get full-upgrade first to ensure your system is running the latest version of all packages. The standard versions available in Ubuntu 16.04.3 will suffice. screen (screen - screen manager with VT100/ANSI terminal emulation, used to connect to serial ports). ![]()
