Connect an HDMI cable to a compatible display and one of the available LVDS ports via an LVDS-to-HDMI adapter to utilize the LVDS output. MIPI DSI One MIPI DSI port is available on the Summit SOM 8M Plus DVK: J22. Connect a MIPI DSI OLED display to utilize the MIPI DSI output. Camera - MIPI CSI The default image for the Summit SOM 8M Plus DVK supports up to two camera inputs as shown in the following table: # of Cameras Resolutions Supported 1 Up to 12MP @ 30fps or 4k @ 45fps 2 Up to 1920x1080 @ 80fps Two MIPI CSI ports are available on the Summit SOM 8M Plus DVK: J20 and J21. Connect a MIPI CSI camera module to one of the available MIPI CSI ports to utilize the camera input. Audio The Summit SOM 8M Plus offers a broad range of audio input/output solutions including a Cadence® Tensilica® HiFi 4 DSP (operating at up to 800 MHz) and ASRC functionality. Input The Summit SOM 8M Plus DVK supports audio input via the following interfaces: HDMI eARC/ARC Combo headphone/mic jack Output The Summit SOM 8M Plus DVK supports audio output via the following interfaces: HDMI Combo headphone/mic jack CAN The Summit SOM 8M Plus supports 2 CAN interfaces which are routed on the DVK to a Texas Instruments TCAN1046V-Q1 transceiver and exposed on header J27 as described below: Pin Number Description 1 CAN2 L 2 CAN2 H 3 Ground 4 CAN1 L 5 CAN1 H UART The Summit SOM 8M Plus supports 4 onboard UART interfaces, and the DVK board adds an additional 4 via a Maxim MAX14830 Quad Serial UART bridge which are described below: UART Name Linux Device Path Description UART1 /dev/ttymxc0 IG60 Serial Module (J14) UART2 /dev/ttymxc1 Cortex-A53 debug UART3 /dev/ttymxc2 NXP 88W8997 radio - Bluetooth UART4 n/a Cortex-M7 debug MAXUART0 /dev/ttyMAX0 Routed to header J17 MAXUART1 /dev/ttyMAX1 Routed to header J18 MAXUART2 /dev/ttyMAX2 Routed to header J13 MAXUART3 /dev/ttyMAX3 Routed to Laird BL5340 module (MOD2) I2C The Summit SOM 8M Plus supports 6 I2C interfaces and, combined with the DVK, a number of peripherals/devices are available as described below: I2C Interface Name Devices I2C1 PMIC - NXP PCA9450 (0x25) I2C2 USB Power Delivery PHY IC - NXP PTN5110 (0x50)Charger IC - TI BQ25792 (0x6b)MIPI CSI1MIPI DSILVDS0LVDS1 I2C3 IO Expander - NXP PCA6416A (0x20)Columb counter - Microchip PAC1932 (0x10)MIPI CSI2*Audio codec - Cirrus Logic WM8960 (0x1a)Audio accessory detection switch - TI TS3A227E(0x3b) I2C4 n/a, pins reserved I2C5 n/a, pins reserved I2C6 Routed to headers J25 and J26 *Address depends on devicetree configuration LTE Cell Modem (Quectel EG25-G) The Summit SOM 8M Plus DVK features an onboard Quectel EG25-G Cat. 4 LTE cellular module which can be used simultaneously with the Wi-Fi and Bluetooth available on the SOM itself. The Quectel EG25-G is supported and managed by ModemManager Inserting the SIM Card The Summit SOM 8M Plus DVK supports the nano (4FF) SIM card form factor, and the slot is located on the underside of the main PCB at CON9. Powering on the LTE Cell Modem The LTE cell modem is powered off by default. To enable it, follow the steps below: Apply power to the LTE cell modem: echo 1 > /sys/devices/platform/gpio/lte_power/value Turn on the LTE cell modem: echo 1 > /sys/devices/platform/gpio/lte_on/value sleep 0.5 echo 0 > /sys/devices/platform/gpio/lte_on/value sleep 0.5 echo 1 > /sys/devices/platform/gpio/lte_on/value Now, the LTE cell modem will boot up and enumerate with ModemManager. Standard ModemManager/NetworkManager commands can now be used to bring the cellular connection online. Check with your cellular provider for the appropriate connection settings (e.g., APN).
