For a sustained technical support, Inforce offers Design Assistance Support Contracts for shorter periods of time and Annual Support Contracts for its customers who would like unlimited prioritized technical support. Please contact Inforce to obtain more details of the support contracts.
Networking, IO and Wireless
19. Does the device support networking and wireless communication?
Supported connectivity includes Gigabit Ethernet, 802.11ac 2X2 MU-MIMO 2.4GHz/5GHz + Bluetooth 4.1LE (available via Qualcomm Atheros QCA6174) and GPS (supported via Qualcomm WGR7640).
20. How can I change the MAC address for WiFi/BT/Ethernet on my board?
MAC addresses are fixed at the factory. Changing them should not be necessary since the correct addresses are programmed before the board is shipped. If it is still required, please refer to the Release Notes and App notes available on Inforce’s TechWeb support portal.
21. What are the IO interfaces available?
Standard I/O interfaces including GbE, I2C, SPI, UART, UIM, GPIOs, and on-board Serial Console are available. The Snapdragon 820 processor supports 1x USB 3.0and 1 x USB 2.0 interfaces. The 6640SBC has one USB 3.0 type A (Host only) and one USB 2.0 micro AB (Device only with OTG support) connector. We also provide a 40 pin expansion header with accessible GPIOs available for users. Please refer to the product specifications in the Hardware Reference Manual or the datasheet for more information.
Software
22. What operating systems are supported and what is the OS roadmap for the Inforce 6640 SBC?
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.
23. 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.
24. 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 6640 SBC) pressed before powering on the board and release it after the board has powered on.
25. 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.
26. 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 6640 SBC 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.
27. 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.
28. 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
