The Inforce 6640 SBC is based on Qualcomm®’s first custom 64-bit quad-core processor, Snapdragon™ 820 (APQ8096 SoC) which is manufactured in an advanced 14nm FinFET Low Power Plus (LLP) fabrication process that allows faster switching speeds and lower voltage operation in a smaller footprint. With better imaging capabilities due to the Spectra™ camera ISP, an improved GPU architecture and excellent video and connectivity options, it is targeted at embedded system applications that require hi-tech smart visual technologies and intense video Analytics. It supports H.265 (HEVC) playback @4K60 and capture @4K30.
As one of the most cutting-edge mobile processors ever created, the Qualcomm® Snapdragon™ 820 processor supports the ultimate in connectivity, graphics, photography, power and battery efficiency. The Snapdragon 820 has been designed from the ground up to be unlike anything else. By combining cutting-edge processing capabilities with power-efficient features, the Snapdragon 820 processor not only works harder than its predecessors, it also works smarter. Additionally, with Snapdragon processors, Inforce Computing offers a clear product release path for embedded device OEMs and developers – starting with production-ready, customizable system-on-modules (SOMs), single-board computers (SBCs) and development kits and scaling up to larger solutions and custom design services. Here're a few salient features and benefits of the Snapdragon 820 processor:
1. Powerful Kryo CPU: The new Qualcomm® Kryo™ CPU has 2x performance and efficiency when compared to the CPU of Snapdragon 810. As the first custom-designed 64-bit quad-core CPU, the Kryo CPU uses Qualcomm® Symphony System Manager as an intelligent resource management tool for Snapdragon that extends control of task scheduling and power management across the entire processor.
2. Efficient Hexagon 680 DSP: Significant improvement to the Hexagon 680 DSP enables the CPU to offload many audio and imaging tasks for more efficient processing. The Hexagon 680 DSP also allows for ultra-low power “always-on” sensors and advanced low power-image processing.
3. Immersive visual graphics: The next-generation of visual processing technologies is finally here, thanks to the power of the new Adreno 530 GPU. As our highest performance GPU yet, the Adreno 530 in the Snapdragon 820 processor along with the Kryo CPU are capable of generating photorealistic graphics for console-quality gaming and next-generation virtual reality apps, while delivering up to 40% improvement to graphics performance and compute capabilities when compared to the Adreno 430.
4. Advanced Spectra Camera ISP: The Snapdragon 820 harnesses the newest innovations in mobile photography to redefine today’s camera capabilities. Supported by the latest 14-bit image sensors, hybrid autofocus and multi-sensor fusion algorithms, the Spectra camera ISP captures a wider range of colors and supports computational photography. Plus, the Snapdragon 820 also has Hexagon 680 with HVX (Hexagon Vector eXtensions), which supports advanced imaging and computer vision.
5. Advanced WiFi: The Snapdragon 820 processor fundamentally changes the way Wi-Fi works with your phone by supporting 802.11ac 2x2 MU-MIMO — which allows Wi-Fi to be up to 3x faster than 802.11ac without MU-MIMO.
If the above features will meet your requirements, Snapdragon 820 processor based Inforce Computing platforms will be a great fit for advanced embedded systems such as
Android 6.x (Marshmallow) BSP release

21. What operating systems are supported and what is the OS roadmap for the Inforce 6640SBC?
Board Support Packages (BSPs) for Android Marshmallow and Nougat are available today as officially supported packages on Inforce TechWeb. An Ubuntu/Debian Linux based BSP would soon be made available and please stay tuned to our website for an announcement on this package. Periodic releases shall be provided with feature improvements on both these packages. Inforce also upgrades the BSPs to newer Android releases and upstream Linux kernel to support feature improvements on its platforms. Please stay tuned for announcements on our website for update releases.
22. Is root access possible on Inforce boards? Could you please explain how to get root privileges in Android?
Yes. As Android derives from the Linux kernel, rooting an Android device gives similar access administrative permissions as on Linux. Please give below commands in adb shell to get root privileges #adb root #adb remount Note that root access to the app space is not provided by default by the BSP.
23. Is fastboot supported? How to enter fastboot?
Yes. To go to fastboot mode, keep the Vol-button (for exact location, check the Quick Start Guide [QSG] document for the Inforce 6640SBC) pressed before powering on the board and release it after the board has powered on.
24. I’ve modified the boot partitions on my board and the board is no longer booting. What should I do?
If the UFS (flash memory) partitions have been erased or the partition table has been corrupted, you may have to obtain a Return Merchandize Authorization (RMA) for the board to be shipped back to Inforce Computing to fix the issue. There are no other alternatives when a board is bricked in this manner. In particular, please avoid erasing the SBL partition.
25. Is the Hexagon DSP available on the Inforce 6640 platform?
Yes. Qualcomm’s Hexagon DSP architecture is designed to deliver performance with low power over a variety of heterogeneous computing applications. It has features such as hardware assisted multithreading, privilege levels, VLIW, SIMD and instructions geared toward efficient signal processing. The Inforce 6640SBC comes with the Hexagon™ 680 DSP with dual-Hexagon vector processor (HVX-512) designed for 825 MHz for ultra-low-power audio and computer vision processing.
Qualcomm also opens up a comprehensive Hexagon SDK for all its processors that provides for a complete environment to generate dynamic HexagonDSP code modules. This SDK would soon be available for the Snapdragon 820. Please check https://developer.qualcomm.com/forums/qdevnet-forums/multimedia-optimization-hexagon-sdk for updates on the SDK availability.
26. How can I get kernel debug messages?
Connect the device’s serial port to the host PC. Boot into fastboot mode and issue the following command –
fastboot -c “console=ttyHSL0,115200n8r androidboot.hardware=qcom” boot boot.img
Debug messages should start to show up.
27. Why isn’t Google Play (previously Android Market) available on my board?
Google Play is part of Google Mobile Services(GMS) and is licensed separately by Google. This is usually available on commercial Android devices. Though our hardware is capable of meeting requirements of the Google Test Suite that would lead to GMS certification, we have not added this to our product. Nevertheless, it is possible to sideload any Android application using the following commands: #adb devices #adb mount #adb remount #adb install apk
