Introduction

1. What is Inforce 6502™ Micro SOM?

The Inforce 6502 Micro SOM is a high performance tiny System on Module (SoM) solution for embedded systems designers. It is based on Qualcomm’s custom Octa-core 64-bit Kryo(260) CPU (Snapdragon 660) processor for embedded applications. The plug-and-play Inforce 6502 Micro SOM comes in an ultra-small form factor of 28mm x 50mm and provides pin, electrical, and form-factor compatibility across a wide product line of Snapdragon processor-based SOMs from Inforce for easy migration.

2. Does Inforce offer a reference carrier board for its SoMs or other form factors based on the Qualcomm Snapdragon 660 processor?

Yes. Inforce offers a reference carrier board for this SoM. All native interfaces of the Snapdragon 660 processor are brought out on this carrier. Please refer to the reference design product page for more details. The reference design comprises of the Inforce 6502 SoM and the carrier board.

3. Does Inforce provide any custom design solutions since some designs wouldn’t be able to use the standard SoM’s form factor and or features?

Yes, while we offer standard products off-the-shelf (OTS) on our website and through our multiple distributors, we also have a strong background in customized hardware and software solutions. We offer pre-validated build-to-order (BTO) configurations, as well as configure-to-order (CTO) options for existing products. For customers wanting to design their own unique form-factor carrier board to interface with the OTS Inforce 6502 Micro SOM, we offer design assistance support packages that include dedicated engineer, reference schematics and design reviews—contact Inforce sales for more details. In addition, Inforce also offers full custom hardware design and associated software/device driver development, for those projects where a unique hardware design is required to meet sophisticated technical challenges.

Software

23. What operating systems are supported and what is the OS roadmap for the Inforce 6502 Micro SOM? /p>

A Board Support Package (BSPs) for Android Oreo is available today as an officially supported package on the Inforce TechWeb. Periodic releases shall be provided with feature improvements on this package. 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.

24. Is root access possible? 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

25. 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 6502 Micro SOM based development kit) pressed before powering on the board and release it after the board has powered on.

26. I’ve modified the boot partitions on my board and the board is no longer booting. What should I do?

If the eMMC (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.

27. Is the Hexagon DSP available on the Inforce 6502 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 6502 micro SoM comes with the Hexagon™ 680 DSP with dual-Hexagon vector processor (HVX-512) designed for 787 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. Please checkhttps://developer.qualcomm.com/software/hexagon-dsp-sdk for downloading the SDK.

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. Please contact our sales team if this is a requirement for your product.

Nevertheless, it is possible to side-load any Android application using the following commands:

#adb devices

#adb mount

#adb remount

#adb install apk
