Introduction
1. What is Inforce 6403 Nano SoM?
The Inforce 6403 Nano SoM is a high performance tiny System on Module (SoM) in a LGA package for embedded systems designers. It is based on Qualcomm’s custom Octa-core 64-bit Kryo (460) CPU (QCS610) processor for embedded applications. The Inforce 6403 Nano SoM comes in an ultra-small form factor of 43mm x 32.5mm and has 324 pins with a pitch of 0.65mm. The carrier board to which this SoM mates has to provision an opening to accommodate the bottom components and this reduces the vertical profile of the product. 
.
2. Does Inforce offer a reference carrier board for its SoM based on the Qualcomm QCS610?
Yes. Inforce offers a reference carrier board for this SoM. Please refer to https://www.penguinsolutions.com/edge/products/reference-designs/qualcomm-qcs610-inforce-6403-reference-design for more details on this development kit. The reference design has the LGA SoM soldered and supports all native interfaces apart from some interfaces achieved through signal conversions like HDMI output. The carrier also includes support for LTE CAT4 through a pre-certified module from Telit. We would be glad to help customers developing their own carriers with custom flip-top sockets during their development phase.
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 6403 Nano 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, we also offer 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 6403 Nano SOM? What do I get when I buy an Inforce 6403 Nano SOM? Is the device available internationally?
Inforce’s website has a lot of useful information about our SOMs at https://www.penguinsolutions.com/edge/products/system-on-modules.Please check on the exact product SKU for the pre-loaded software, available memory and supported temperature ranges.

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 are the IO interfaces available?
Standard I/O interfaces including I2C, SPI, UART, UIM and GPIOs are available. The Qualcomm QCS610 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.
Software
24. What operating systems are supported and what is the OS roadmap for the Inforce 6403 Nano SoM?
Board Support Packages (BSPs) for Android 10 and Linux are available today as officially supported packages on the Inforce TechWeb. Periodic releases shall be provided with feature improvements and bug fixes on both these package. We also upgrade the BSPs to newer Android releases and newer Linux kernels to support feature improvements on its platforms. Please stay tuned for announcements on our website for update releases.
25. 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
26. 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.
27. 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.
28. Is the Hexagon DSP available on the Inforce 6403 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 6403 micro SoM comes with the Hexagon™ 685 DSP with dual-Hexagon vector processor (HVX-512) designed 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.
29. 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 apkShould you have further questions not answered by the above FAQ and would like to have them included here, please contact PenguinEdgeSales@penguinsolutions.com.
