Valgrind Tools

The Valgrind Tool Suite v3.12.0 is included with Ref-OS-IoT (see http://www.valgrind.org). Valgrind's tools allow advanced analysis of how your programs perform memory management, threading and other features. The tools included in this port of the suite are:

Module Sourced Accessory Power

The +VDD1 and +VDD3 power rails rise during cold boot of the module PMIC, so both rails are stable before the SoC is taken out of the reset and before code execution starts. They are intended to activate voltage regulators on the expansion board so system devices can be available when the module code execution begins.

USB2 OTG Host Connectivity

If a simple design is the goal, USB2 port 0 can serve as a USB host. This allows combining host and device mode to be delivered through just one connector (typically a micro-A or -B connector). The USB2 interface is able to transmit data at 480Mbps. For higher speeds a USB3 is necessary.

 

SPI Interface

The expansion board routes two SPI interfaces from the module, through a level translator to convert the module 1.8 V logic levels to those required by the breakout board. The breakout board should include appropriate pullup values to the desired voltage, but not to exceed 3.3 V.

96Boards Compatible Carrier Board

Intel provides a 96Boards™ compatible reference design for the 5xx series compute module, including circuit board files, the PCB bill of material, a technical user guide and CAD models of the board under the Creative Commons v3 (unported) License. A copy of the license is included within the download package.

It is important to note that this item is not offered by Intel as a product and no support is provided for this design.

Booting the Development Platform

My USB device won’t show up at all in BIOS

Try using a different USB device, port, or USB hub.

My development platform won’t boot from a USB drive or microSD* card

First, make sure that your microSD card or USB device is securely connected to the development platform. Also make sure you don't have a microSD card and a USB drive plugged into the development platform at the same time.

Power On

While this section outlines a typical first time power on sequence, most of these steps will be repeated during product development as new BIOS updates are installed or the developer chooses to return their platform to a factory state.

The following topics explain a the typical process to power on your platform:
