Once the binary image has been generated, we can upload it to the OpenMote - B board using the bootloader and the cc2538 - bsl Python script. To upload the firmware, issue the following command: sudo scons board=openmote - b project=freertos - cc2 538 compiler=gcc verbose=0 bootload=/dev/ttyUSB1 Notice that the command must be prepended with “sudo”, as accessing the serial port in Linux requires super - user permissions. If the process is successful, the build system will display a success message, a s depicted in the next image, and the OpenMote - B should start working: the green LED should blink briefly (100 ms) every second (1000 ms) and the user button should toggle the red LED.

SKU: IS.OMB - 001 Rev. 0: 22 - 08 - 2019 15 Software This section is aimed at providing a starting point to run the main open - source software projects on the OpenMote - B hardware. 6.1 Prelim in a r i e s To program the OpenMote - B boards with the various open source software projects it is necessary to have a working environment to build, upload, and debug the code for the ARM Cortex - M3 processor. It is possible to create a working environment with either Windows or Linux, as described next. Macintosh is known to work, but the former operating systems are preferred as they have been thoroughly tested. Hence, the following steps show how to install the tools required to compile, run and debug embedded software on the OpenMote - B boards using either Windows 10 or Ubuntu 18.04 LTS. The process assumes that the user has a working installation of either operating system, either natively on thei r computer or in a virtual environment (i.e. VMWare Workstation or VirtualBox). The tools that are required are: • Python 3 with the SCons, PySerial and IntelHex packages • GCC compiler for ARM Embedded Processors 6.2 Windows 10 6.2.1 Python 3.x To install Python 3.x go to the official website and download the latest version 1 . 1 https://www.python.org/downloads/windows/

11. SKU: IS.OMB - 001 Rev. 0: 22 - 08 - 2019 11 • Antenna connectors: The main board includes two SMA antenna connectors for the Sub - GHz and 2.4 GHz antennas. The Sub - GHz antenna connector is directly connected to the Sub - GHz radio on the AT86RF215. The 2.4 GHz antenna is multiplexed using an RF switch to the CC2558 and the AT86RF215 radio transceivers. The direction of the RF switch can be controlled using two CC2538 pins. • Power : The main board can be powered from a USB port (5V) through an A male plug connector, or from two AA batteries (3V) located on the back of the board. The board features an auto - switching mechanism that selects the USB source whenever it is available and seamlessly transitions to the AA batteries when disconnected. Finally, the board includes an on/off button to disconnect the two AA batteries when not used. • Current sensing: The main board includes two ports (3 pins with 2.54 mm spacing) to measure current consumption of the whole system during operation. The first port measures the current consumption of the CC2538 chip, whereas the second po rt measures the current consumption of the AT86RF215 chip. • JTAG port: The main board includes a 10 - pin ARM connector that allows to load and debug code using an external JTAG probe. The interface is compatible with the main toolchains: Code Composer Stud io, IAR Embedded Workbench and ARM. System overview 4.1 Texas Instruments CC2538 The Texas Instruments CC2538 is a wireless micro - controller SoC (System on Chip) targeted at high - performance applications. It combines a powerful ARM Cortex - M3 running at 32 MH z, with 32 Kbytes of RAM and 512 Kbytes of Flash, with a robust 2.4 GHz radio transceiver compatible with the IEEE 802.15.4 standard. In addition, the CC2538 includes various peripherals to interface the processor with other systems: 2x SPI, 2x UART, 1x I2 C.

In addition, the main board also includes a reset button that allows to perform a hardwa re reset. • Serial communications: The main board can communicate with a computer using a UART port on the CC2538. The solution is based on the FTDI FT2232H chip, a Serial - to - USB converter that allows to communicate with a computer using a standard UART por t. In addition, the FTDI chip allows to program the CC2538 directly using the internal bootloader and the cc2538 - bsl Python script. • Board expansion : The main OpenMote - B board includes an expansion port (8 pins with 2.54 mm spacing) that can be used for d ebugging or to connect daughter boards, i.e., the OpenMote - B sensors board. The expansion board includes a VCC (2.5V) and a GND pin, as well as six configurable pins. • Extended security : The main OpenMote - B board includes hardware - accelerated support for cryptographic functions using SHA2, AES - 128/256, ECC - 128/256 and RSA algorithms.
