1. What is Inforce 68A1 Micro SoM?
The Inforce 68A1 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(585) CPU (QCS8250) processor for IoT applications. The plug-and-play Inforce 68A1 Micro SoM comes in a small form factor of 35mm x 53mm.
2. Does Inforce offer a reference carrier board for its SoMs or other form factors based on the Qualcomm Snapdragon 845 processor?
Yes. Inforce offers a reference carrier board for this SoM. Most of the native interfaces of the QCS8250 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 68A1 SoM and the carrier board. We would be glad to help customers design their own carrier boards.
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 68A1 Micro SoM, we offer design assistance support packages that include dedicated engineer, reference schematics and design reviews—contact our sales team 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.

We offers a range of standard products off-the-shelf (OTS) on its website and through our distributors (Arrow/Mouser/Atlantik). 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, 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 PenguinEdgeSales@penguinsolutions.com to obtain more details of the support contracts.
20. Is there a way to automatically boot up the reference design, when the system is electrically powered?
Yes, this is possible but will involve a hardware rework. On the carrier board, please mount a 0Ω resistor for R243 (location shown below). Do note that the warranty becomes void once the hardware is modified by you.
Networking, IO and Wireless
21. Does the device support networking and wireless communication?
Supported connectivity includes 802.11ax 2X2 MIMO WiFi 6 + Bluetooth 5.1LE (available via WCN3990).
22. 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.
23. What operating systems are supported and what is the OS roadmap for the Inforce 68A1 Micro SoM?
A Board Support Package (BSPs) for Android 10 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 when available from Qualcomm, to support feature improvements on its platforms. Please stay tuned for announcements on our website for update releases.
24. 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
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 68A1 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 68A1 micro SoM comes with the Hexagon™ 690 DSP with dual-Hexagon vector processor 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 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
