MARS Board Super ARM DIY platform selection Freescale I.MX6 Cortex-A9 dual-core processor is because this processor is powerful, multimedia is more powerful, and it can be extensive in the application. Let's introduce Freescale. I.MX6 processor
Freescale I.MX6 series processor
The I.MX 6 Series processor launches the industry's first multi-core platform with true scalability, including single core, dual-core, and quad-core series based on ARM® CortexTM-A9 architectures. With the support of powerful ecosystem, the I.MX 6 Series becomes an ideal platform for developing a single hardware design-based terminal product. The I.MX 6 Series has high performance multimedia processing, pin *, and software compatible, and built-in power management, which is specifically built for smart devices in the new era.

Mars Board
· Compatibility
MARS Board defaults to I.MX 6DUAL processor, while Mars Board provides customable services, because i.mx6 dual and i.mx6quad processor PIN-TO-PIN is compatible, it can be replaced with I.MX6QUAD processor, software Compatible, no need to modify, soft hardware seamless switching.
· A variety of display interfaces
MARS Board supports multiple display interfaces, where the LCD interface can be set with a 4.3-inch and a 7-inch liquid crystal display, support resistor touch screen input; LVDS interface can be used with a 9.7-inch LVDS display, support capacitive touch screen input; HDMI interface With the HDMI HD display, the resolution can support 1080p60. The display and this diversified display interface just meets the diversification and individualization needs of different customers for different applications.
· A variety of operating systems
Mars Board supports UCOS-II, Ubuntu 11.10, Android 4.0.4 multiple operating systems to meet the needs of different users. By modifying the code, AMP can be implemented (each CPU routine different operating system), theory supports UCOS-II, Ubuntu, Android operating system, now we offer UCOS-II with ubuntu demonstration Demo. MARS Board's support for multiple operating systems allows software engineers with better development space. Different system engineers can do varying degrees of development work based on this platform. The relevant BSP packs provided by MARS Board also give engineers an assessment of an assessment.

· tablet
Android 4.0.4 system, with the LCD8000-97C display module, 1024x768 resolution, multi-point capacitive touch screen input, simple steps can be built with an Android tablet processing.
· HD Internet TV box
Android 4.0.4 system, HDMI HD interface, 10 / 100m / 1Gbps Ethernet interface (can connect to Wi-Pi module extension wireless network), home theater is not a dream.
· Arduino Shields
The seamless combination of MARS Board, Embedded Pi and ArduinonioDe brings a new hardware combination mode to evaluate a new experience of Engineers from Ardunio, Embedded Pi and Mars Board Hardware Platform.
. The extension interface provided by MARS Board has rich IO information, which is compatible with existing Arduino Shields by connecting Embedded Pi. Among them, Embedded Pi acts as the Adapter between MARS Board and Arduino Shields, MARS Board and Embedded PI communicate through the UART / I2C / SPI interface, thereby establishing contacts with Arduino Shields connected to the Embedded Pi. . Subsequent, a separate technical article will be made in this new type of hardware combination mode.
· AMP (ASYMMETRIC MULITIPROCESSING) operating system
To make full use of multi-core advantages, implement the AMP operating system, MARS Board is made. A routine UCOS-II, a routine Ubuntu, the real-time control section is handed over to UCOS-II, and the interface exchange is handed over to Ubuntu, an interesting application is a self-balance truck.
