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 (SD660) processor?
Yes. Inforce offers a reference carrier board for this SoM. All native interfaces of the Qualcomm SDA660 (Snapdragon 660) processor are brought out on this carrier. Please stay tuned to our website for more details and availability on the reference design which shall comprise of the Inforce 6502 SoM and the reference carrier.
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.
4. Where can I find more information about the Inforce 6502 Micro SoM? What do I get when I buy an Inforce 6502 Micro SoM based reference design? Is the device available internationally?
Inforce’s website has a lot of useful information about our SoM based reference design at https://www.penguinsolutions.com/edge/products/reference-designs.
Please check on the exact product SKU for the pre-loaded software and supported temperature ranges. The Inforce 6502 Micro SoM requires a carrier board (like all SoMs do) to power up and connect to peripheral devices and gain access to the extensive set of I/Os that are available on the Micro SoM.

Supported connectivity includes 802.11ac 2X2 MU-MIMO 2.4GHz/5GHz + Bluetooth 5.xLE (available via WCN3990) and GPS (supported via Qualcomm SDR660G).
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 I2C, SPI, UART, UIM and GPIOs are available. The Qualcomm Snapdragon 660(SDA660) processor supports 1x USB 3.1 gen1 and 1 x USB 2.0. Please refer to the product specifications in the Hardware Reference Manual or the datasheet for more information.
22. What operating systems are supported and what is the OS roadmap for the Inforce 6502 Micro SoM?
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.
23. 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
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 6502 Micro SoM based reference design) 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 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.
26. 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 check https://developer.qualcomm.com/software/hexagon-dsp-sdk for downloading the SDK.
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. Please contact our sales team at PenguinEdgeSales@penguinsolutions.com if this is a requirement for your product.
Nevertheless, it is possible to side-load any Android application using the following commands:
#adb install apk
