Embedded Software Insight
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 designs using an embedded file system. 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
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
In this article, we show that TSFS transactions go beyond preserving file-level integrity, and can also be used to enforce coherence across multiple files and directories. To support the discussion, we present a real-life application example and demonstrate how a single additional call to tsfs_commit() is all that is needed to make the code immune to unexpected failures.
In this second article in this series we see how an application can be designed to withstand such unforeseen events, using TSFS transactions. Doing so, we introduce the tsfs_commit() API. We also discuss the write transaction atomicity property, by which applications can be safely designed ignoring potential partial update issues.
This is the first article of a three-part series on fail-safe, storage-related application design using an embedded file system. The first part of the series lays out the fundamental problem of unexpected failures and briefly discusses partial solutions. The second part introduces how a fail-safe transactional file system such as the TREEspan File System (TSFS)
Last week was one of pride and excitement for the JBLopen’s development team as we released our latest product, the TREEspan File System (TSFS). After the official announcement and presentation, we feel the need to introduce the newcomer in a more personal way, such as we see it from the inside. Above all, we would
