Embedded Software Insight
A look at the evolution of Express Logic X-Ware and ThreadX into Microsoft Azure RTOS. Looking back at previous acquisitions of embedded software companies and what’s different with Microsoft.
QSPI NAND is a memory technology specifically designed as a direct alternative to its popular cousin, QSPI NOR. But what exactly is QSPI NAND? How does it compare to QSPI NOR? How does it compare to parallel NAND? This is what this article is all about.
In this second part of this guide on how to set up an embedded GCC toolchain within Eclipse on Linux, we’ll pick up on where we left off at the end of Part 1. We’ll take a look at workspace configuration and creating both managed and Makefile based projects.
This guide is the first part of a Linux version of the guide we previously wrote dealing with setting up an embedded software toolchain within Eclipse. This guide is targeted at readers who need to set up a GCC toolchain within a vanilla Eclipse installation.
In this article we’ll leave the package attributes behind to focus on the internal features of QSPI devices, starting with the memory organization. This article will cover the overall capacity, multi-stack devices as well as the memory map organization units such as pages, blocks and sectors.
In this first article, we’ll go over some important considerations to keep in mind when using a NOR for code shadowing or execute in place, and explain how these considerations may change when using the NOR for data storage with a file system. Then we’ll take a quick look at the hardware characteristics of QSPI NOR devices.
In-depth comparison between NOR and NAND covering aspects of NOR and NAND flash technologies that, in our view, are too often ignored including the impact of the application requirements on the choice of Flash technology.
Let’s explore and compare two different paradigms of flash management commonly used throughout the industry: managed flash and unmanaged flash. Managed flash devices include SD cards, USB flash drives, eMMC and UFS modules — also SSDs, but those are less often seen in embedded systems. These are all NAND-based devices.
This article is the first of an introduction series about flash memory with a focus on embedded systems. A high-level introduction shall we say. Not the kind that takes you straight to the electron and drags you through the depths of quantum physics. No. The purpose of this series is to provide useful information from
In this article we’ll look at the last step of setting up a C/C++ embedded development project within Eclipse CDT. Which is creating and launching a debug configuration for the project. The kind of project managed or Makefile base does not affect the debugging process so these instructions applies to both types of projects.
In the previous article of this series on TSFS snapshots, we have shown how snapshots can be used to design a simple yet robust firmware upgrade procedure. This time, we go from design to implementation, delving into the specifics of the TSFS snapshot management interface. More specifically, we show how we can meet our initial
This article is the first part of a twofold series on one of the most unique TSFS feature: snapshotting. In this first article, we show how snapshots can ease application development, providing the application designer with an elegant way of handling concurrent read/write accesses. We also introduce a simple firmware update example, to help us
