In order to assemble, you’ll need to attach the antenna carrier board to the main board. To assemble, complete the following steps: Insert one plastic riser into the marked corner hole, which does not come in contact with the L-shaped antenna board. Secure with one plastic nut. In the remaining four stand holes on the board, insert a riser beneath the board, and secure another riser above the board in the threaded underside of a second plastic riser, as show. Place the antenna carrier board over the top risers, aligning the holes in the antenna board with the threaded end of the upper risers. Secure with four plastic nuts. Connect the two LTE antenna cables to the LTE MAIN and LTE DIV connectors as shown. Connect the two FlexMIMO antenna cables to the WIFI and WIFI/BT connectors as shown. Preparing the microSD Card By default, the Summit SOM 8M Plus onboard eMMC ships without an image, so a microSD card (minimum capacity of 8GB) must be used to boot the board. Follow the steps below to prepare the microSD card: Download the Latest Release Package Download and extract the latest release package from the Ezurio Summit SOM 8M Plus Releases GitHub repository. These release packages are named image-summitsom-cmd-laird-A.B.C.D.tar.bz2 (where A.B.C.D is the release version number), and inside you will find a number of important files: File name Description image-summitsom-cmd-imx8mp-summitsom-A.B.C.D.rootfs.wic.bz2 Prebuilt SD card image image-summitsom-cmd-imx8mp-summitsom-A.B.C.D.swu swupdate update file Flash the Prebuilt Image Flash the image to the microSD card using one of the guides below: dd (Ubuntu) The prebuilt image is distributed as a `.wic.bz2` file which can be flashed to a microSD card using `bzcat` and `dd` as shown below, substituting the proper path to the `.wic.bz2` image file and target device (e.g., `/dev/sdb`): umount /dev/sdX? && bzcat image-summitsom-cmd-imx8mp-summitsom-A.B.C.D.rootfs.wic.bz2 | sudo dd of=/dev/sdX bs=1M conv=fsync sync balenaEtcher (Windows, macOS, Ubuntu) The prebuilt image is distributed as a `.wic.bz2` file which can be flashed to a microSD card across many OS platforms using the balenaEtcher tool. Get balenaEtcher Download and install the balenaEtcher application for your platform from https://www.balena.io/etcher. Follow the prompts to properly install the application to your system. Launch balenaEtcher Load the image file Click the "Flash from file" button and navigate to the '.wic.bz2' image file. NOTE: The balenaEtcher application will decompress the image on the fly as part of the flashing process. Select the target Click the "Select target" button and choose the target device which represents your microSD card. WARNING: Verify the proper device has been selected as the contents of the disk will be overwritten! Flash the image Click the "Flash!" button to begin the flashing process. NOTE: Flashing the image requires elevated permissions, so you may be asked to enter admin credentials. Insert the microSD Card into the Board Once the image has been flashed to the microSD card, insert it into the microSD card slot (CON3) on the Summit SOM 8M Plus DVK. Booting to Linux Follow the steps below to boot the DVK from a microSD card: Connect the USB Debug Cable Connect the supplied Micro USB cable to the port labeled ‘Debug UART’ (J2) and connect the other end to a development PC. This will expose four UART connections on the development PC - the third port is for the application (Cortex-A53) core, and the fourth one is for the MCU (Cortex-M7) core. Connect Terminal Application Start a terminal application and connect to the third UART port (the one for the Cortex-A53 core) using the following settings: Port Setting Value Baud rate 115200 Data bits 8 Stop bits 1 Parity None Flow control None For detailed instructions on setting up a terminal application, see one of the guides below for your operating system: Ubuntu (Minicom) Determine the correct port to use. Run the following command from the terminal to list the available ports: ls /dev/ttyUSB* As stated above, the Summit SOM 8M Plus DVK exposes four UART connections (with the third being the target port). Therefore, the second-to-last port is the correct one. Download and install Minicom (if not already present). Run the following commands to install Minicom: sudo apt-get update sudo apt-get install minicom Launch Minicom on the correct port. Run the following command to launch Minicom replacing `x` with the correct port as determined in the previous step: sudo minicom -D /dev/ttyUSBx -b 115200 NOTE: sudo is necessary to run Minicom unless your user has been added to the dialout user group.
