The Multimedia CPU i.MX 8M from NXP (4x ARM® Cortex®-A53 (64 Bit) with 1.5GHz & Cortex®-M4 CPU) is perfect for applications with demanding graphics in building automation, all kinds of HMI in industry and medical technology, as well as POS and POI terminals. With Linux on the Cortex®-A53 cores and FreeRTOS on the Cortex®-M4 core, NXP continues its heterogeneous concept and offers an ideal possibility for real-time processing.
For graphics processing the CPU offers OpenGL/ES 3.1, OpenGL 3.0, Vulkan, OpenCL 1.2 as well as the playback of videos up to 4Kp60. F&S Elektronik Systeme (manufacturer of embedded boards for more than 20 years with headquarters in Stuttgart) has placed this powerful CPU on the new Single Board Computer armStone™MX8M (PicoITX format). Up to 8GB LPDDR4 RAM, 1GB SLC NAND Flash and additionally up to 64GB eMMC, as well as USB3.0, Audio IN/OUT/MIC, Gigabit Ethernet, mPCIe (SIM Slot), MIPI CSI, 3x I2C, SPI, 4x UART, CAN and SDIO (uSD Slot) are available. 2x LVDS (up to FullHD) and DVI up to 4k are available for display interface. A resistive or PCAP touch panel is connected via I2C. Another option is an OnBoard WLAN/BT module (pre-certified) with antenna socket.
As with all armStone™ single board computers, many of the signals are on common connectors or on the 66-pin feature bus. The armStone™MX8M is powered by 5V (a pluggable 12/24V adapter is offered as an accessory), the power consumption is only a few watts. With a temperature range of up to -20°C – +70°C, the armStone™MX8M can also be used outdoors. Linux (Buildroot, Yocto follows) is available as operating system. This has already been ported by the experienced software team of F&S Elektronik Systeme. Bootloader, device tree, customized interface drivers and all tools necessary for development are available. Various security functions are made available by the Linux adaptation of F&S Elektronik Systeme.
