| Note: If you are using Windows and get a <code>no device found</code> error, you will need to install the usb driver. Download <a href="http://zadig.akeo.ie">Zadig</a> and run it:</p> |
| <ul> |
| <li>Select Options > List All Devices.</li> |
| <li>Select <code>Olimex OpenOCD JTAG ARM-USB-TINY-H</code> from the drop down menu.</li> |

| <h3 id="connect-newtmgr-with-the-board-using-a-serial-connection">Connect Newtmgr with the Board using a Serial Connection</h3> |
| <p>Locate the PC6/USART6_TX (pin 3), PC7/USART6_RX (pin 4), and GND (pin 2) of the UEXT connector on the Olimex board. More information on the UEXT connector can be found at <a href="https://www.olimex.com/Products/Modules/UEXT/">https://www.olimex.com/Products/Modules/UEXT/</a>. The schematic of the board can be found at <a href="https://www.olimex.com/Products/ARM/ST/STM32-E407/resources/STM32-E407_sch.pdf">https://www.olimex.com/Products/ARM/ST/STM32-E407/resources/STM32-E407_sch.pdf</a> for reference.</p> |
| <p><img alt="Alt Layout - Serial Connection" src="../pics/serial_conn.png" /></p> |
| <ul> |
| <li>Connect the female RX pin of the USB-TTL serial cable to the TX (Pin 3) of the UEXT connector on the board.</li> |
| <li>Connect the female TX pin of the USB-TTL serial cable to the RX (Pin 4) of the UEXT connector on the board.</li> |
| <li>Connect the GND pin of the USB-TTL serial cable to the GND (Pin 2) of the UEXT connector on the board.</li> |
| </ul> |
| <p><br> |
| Locate the port, in the /dev directory on your computer, that the serial connection uses. The format of the port name is platform dependent:</p> |
| <ul> |
| <li>Mac OS uses the format <code>tty.usbserial-<some identifier></code>.</li> |
| <li>Linux uses the format <code>TTYUSB<N></code>, where <code>N</code> is a number. For example, TTYUSB2.</li> |
| <li> |
| <p>MinGW on Windows uses the format <code>ttyS<N></code>, where <code>N</code> is a number. You must map the port name to a Windows COM port: <code>/dev/ttyS<N></code> maps to <code>COM<N+1></code>. For example, <code>/dev/ttyS2</code> maps to <code>COM3</code>.</p> |
| <p>You can also use the Windows Device Manager to find the COM port number.</p> |
| </li> |
| </ul> |
| <p><br></p> |
| <div class="codehilite" style="background: #ffffff"><pre style="line-height: 125%;"><span></span><code>$ ls /dev/tty*usbserial* |
| /dev/tty.usbserial-1d13 |
| $ |
| </code></pre></div> |
| |
| <p><br> |
| Setup a newtmgr connection profile for the serial port. For our example, the port is <code>/dev/tty.usbserial-1d13</code>.</p> |
| <p>Run the <code>newtmgr conn add</code> command to define a newtmgr connection profile for the serial port. We name the connection profile <code>stm32serial</code>. </p> |
| <p><strong>Note</strong>:</p> |
| <ul> |
| <li>You will need to replace the <code>connstring</code> with the specific port for your serial connection.</li> |
| <li>On Windows, you must specify <code>COM<N+1></code> for the connstring if <code>/dev/ttyS<N></code> is the serial port.</li> |

| <h3 id="use-newtmgr-to-query-the-board">Use Newtmgr to Query the Board</h3> |
| <p>Run some newtmgr commands to query and receive responses back from the board (See the <a href="newtmgr/overview">Newt Manager Guide</a> for more information on the newtmgr commands).</p> |
| <p>Run the <code>newtmgr echo hello -c stm32serial</code> command. This is the simplest command that requests the board to echo back the |
