13. What are the camera capabilities of the Inforce 6620 SBC?
The Inforce 6620 SBC does not have a MIPI-CSI connector onboard. The native MIPI-CSI interfaces are used to derive a HDMI video input that is capable of recording 4K30 videos and 21 MP images.
Our platforms are typically validated with a Sony IMX230 sensor (21MP) based camera module for 4K@30fps capture and record. This module can be purchased as an accessory from https://www.penguinsolutions.com/edge/products/accessories
14. How much power does the board draw? Is it possible to measure the power?
The Inforce 6620 SBC is powered by a 12V/2A wall adaptor. Our products typically offer support for 7V-16V power input range. The total approximate power drawn by the Inforce 6620 SBC ranges between 6W to 17W when different use cases are executed.
There could be test points made available on the board to measure run-time power. Please refer to the user guide for more details on these test points. The input current through the DC jack can also be measured during different usecases. Note that we run the Qualcomm Trepn™ profiler as part of our validation process on all of our stock Android releases.
15. What are the audio capabilities?
Audio is available through HDMI, USB, and speaker out. The Inforce 6620 SBC also comes with a microphone for recording and a combo jack for microphone and speaker out. The HDMI interface has an 8 channel audio with 7.1 channel surround sound, with support to Dolby Digital Plus, Dolby True HD and DTS-HD Master.
16. What documents are provided? Are board design files also provided?
We provide datasheets, user guide and a Hardware Reference Manual. Board design files and schematics are proprietary and are the intellectual property of Penguin Edge, and hence not provided.
All software releases are accompanied with release notes, user guides and application notes that describe the installation procedure.
17. What is the support model from Inforce after products are purchased?
Inforce offers a range of standard products off-the-shelf (OTS) on its website and through our distributors. Apart from these, it offers pre-validated build-to-order (BTO) configurations, as well as configure-to-order (CTO) options for existing products. In addition, we also offer full custom hardware design and associated software/device driver development, for those projects where a unique design is required to meet sophisticated technical challenges. All purchases of our products get unlimited access to the online TechWeb support portal, which provides a host of technical documentation and software downloads. Purchasers are also provided free technical support for two support tickets. For a sustained technical support,we offer 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 PenguinEdgeSales@penguinsolutions.com to obtain more details of the support contracts.
Networking, IO and Wireless
18. Does the device support networking and wireless communication?
Supported connectivity includes GbE uplink, 802.11ac 2X2 MU-MIMO 2.4GHz/5GHz + Bluetooth 4.1LE (available via Qualcomm Atheros QCA6174A).
19. Does the platform support PoE?
Yes, the platform supports PoE out of the box and no additional accessories are required. The platform provides GbE uplink through a PCIe to GbE controller that enable Power Over Ethernet (PoE) supporting 802.3at complaint PD configuration. This allows the user to power the system from PoE enabled switches using a single cable.
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 the TechWeb support portal.
21. What are the IO interfaces available?
Standard I/O interfaces including GbE, USB-SS, USB-C (USB HS), and on-board Serial Console are available. The Snapdragon 820 processor supports 1x USB 3.0 and 1x USB 2.0 interfaces. The 6620 SBC has two USB 3.0 Type A (Host only) ports and one USB-C (USB 2.0) (Device only connector. 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 6620 SBC?
A Board Support Package (BSP) for Android Nougat is available today as an officially supported package on Inforce TechWeb. Periodic releases shall be provided with feature improvements on this package. Inforce also upgrades the BSPs to newer Android releases 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 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 can recover through a procedure that uses the USB port. Please logon to our Techweb repository to access the necessary document.
26. Is the Hexagon DSP available on the Inforce 6620 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 6620 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 Hexagon DSP 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.
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 side-load any Android application using the following commands: #adb devices #adb mount #adb remount #adb install apk
