The primary features listed below by domain and any related expansion board hardware or operating system elements required to enable the basic functionality are also described.
The steps in this section outline how to navigate the BIOS menu system to change the power limit settings; the module will throttle the CPU to keep current power below the set PL1 target.
This section outlines key system and host environment configuration elements needed to build the reference operating system.
The following configuration and Yocto workflow is based on a workstation running Linux*. Examples provided have been tested with Ubuntu* 16.04 and should work on most modern distributions if adapted by a knowledgeable developer.
The diagram below shows the high level software stack that is available to an imaging module connected to the Camera Serial Interface (CSI) bus to the internal Image Processing Unit (IPU) within the SOC.
Reference Operating System for IoT includes various widely used debug tools for Bluetooth® :
These tools provide the --help option about usage. Also, there are many resources available publicly to help you use these tools.
The Intel® Joule™ platform offers multiple solutions for data retention: eMMC, SD Card, and SDIO. Each storage type is intended for a specific use but offers the developer the flexibility to choose between them.
The module contains an embedded MultiMedia Card (eMMC) with ether 8GB or 16GB of storage capacity. See the System on Module Overview for module configurations.
The Intel® Joule™ module contains an integrated Intel® Dual Band Wireless-AC 8260 adapter.
All module GPIO lines function at 1.8 V levels. Intel® Joule™ expansion board provides appropriate level transition, signal conditioning, and protection for devices on—or devices connected to—the expansion board. The default pin usage of J2 and J3 refers to the vantage point of the module. For example the ISH_GPIO_0 signal originates in the module and is delivered to the expansion board; therefore, ISH_GPIO_0 is an output (as configured by BIOS).
