Firmware

By • Technical Features Writer What is firmware? Firmware is programming that's written to a hardware device's Firmware is installed directly onto a piece of hardware during manufacturing. It is used to run user programs on the device and can be thought of as the software that enables hardware to run. Firmware is the foundation of the software stack that computer hardware uses for basic operations and to run applications. Hardware makers use American computer scientist Ascher Opler is said to have coined the phrase firmware in a 1967 issue of the publication Datamation. He used the term to describe a type of microprogram in between hardware and software. Today, embedded firmware exists in everything from smartphones to internet of things ( Why are firmware updates important and how do they work? Firmware updates are often issued to fix Some examples of firmware updates include the following: • A CD disc writer gains the ability to burn a new type of disk. • A • A Some internet-connected devices regularly check for new firmware and automatically download and install it. Other device manufacturers require the user to visit the manufacturer's website to download and install firmware updates manually. Manufacturers release updates on a regular basis. The frequency of firmware updates will vary depending on the device. The firmware in a Over-the-air updates are a common way for IoT devices to upgrade their firmware. Many electronic devices also require that the device remains p...

How to Apply Firmware Updates It's impossible to give a blanket answer for how to install firmware on all devices because not all devices are the same. Some updates are applied wirelessly and just seem like a regular software update. Others may involve copying the firmware to a portable drive and then loading it onto the device manually. For example, you might be able to update the firmware on a gaming console by just accepting any prompts to update the software. It's unlikely that the device is set up in a way where you have to manually download the firmware and then manually apply it. That would make it much too hard for the average user to perform updates, especially if the device needs to be updated often. Apple devices like iPhones and iPads also occasionally get firmware updates, as do Android phones and tablets. These devices let you download and install the firmware from the device itself so you don't have to do it yourself manually. Typically, firmware updates for mobile devices are obtained wirelessly, in which case they might be called firmware-over-the-air (FOTA) or over-the-air updates. However, some devices, like most routers, have a dedicated section in the administrative console that lets you apply a firmware update. This is generally a section with an Open or Browse button for selecting the firmware you've downloaded. It's important to review the device's user manual before doing this, just to make sure the steps you're taking are correct and you've read a...

In this article This article describes how to update a removable or in-chassis device's firmware using the Windows Update (WU) service. For information about updating system firmware, see To do this, you'll provide an update mechanism, implemented as a device driver that includes the firmware payload. If your device uses a vendor-supplied driver, you have the option of adding the firmware update logic and payload to your existing function driver, or providing a separate firmware update driver package. If your device uses a Microsoft-supplied driver, you must provide a separate firmware update driver package. In both cases, the firmware update driver package must be universal. For more info about universal drivers, see Because WU can't execute software, the firmware update driver must hand the firmware to Plug and Play (PnP) for installation. Firmware update driver actions Typically, the firmware update driver is a lightweight device driver that implements the following procedures: • At device start or in the driver's EVT_WDF_DRIVER_DEVICE_ADD callback function: • Identify the device to which it's attached. • Determine whether the driver has a firmware version that is more recent than the version on the firmware currently flashed on device hardware. • If a firmware update is necessary, set an event timer to schedule the update. • Otherwise, do nothing until the driver is started again. • During system runtime: • If an update is queued, wait for a set of conditions to be met...

In this article, Opler was referring to a new kind of computer program that had a different practical and psychological purpose from traditional programs from the user's perspective. As computers began to increase in complexity, it became clear that various programs needed to first be initiated and run to provide a consistent environment necessary for running more complex programs at the user's discretion. This required programming the computer to run those programs automatically. Furthermore, as companies, universities, and marketers wanted to sell computers to laypeople with little technical knowledge, greater automation became nece...

In this article Windows supports a platform for delivering system and device firmware updates wrapped in driver packages that are delivered using Microsoft Windows Update (WU) and then handed off to and processed in the UEFI UpdateCapsule function. This platform provides a consistent, reliable firmware update experience, and it improves the ability to deliver important system firmware updates for end-users. This ability has been available as early as Windows 8.1. However, some recent changes require that firmware providers combine Computer Hardware ID (CHID) targeting along with a model unique EFI System Resource Table (ESRT) UEFI_RES\ and record this for later use. Microsoft has guidance on how to create a UNIQUE ID, for these scenarios. This guidance is in the downloadable document for In this section

Did you know that firmware is literally everywhere? It might be strange to think about – but it's just as common as hardware and software. In fact, it is thanks to firmware that: • Printers work • Defibrillators work • Car radios works • and more … Based on the examples above, you probably already have some idea of what firmware is. But you don't have a clear definition of it. In order to truly understand what firmware is, we must first understand software, then hardware, and finally we can jump into firmware. In this tutorial, I'll explain each topic with an analogy. By doing so, everyone can understand. It doesn't matter if you're just getting into technology! With that, I would like to make sure that everyone understands what software, hardware, and firmware is. I will not elaborate on the technical terms. In this article we will explore: • What exactly is software? • What exactly is hardware? • What exactly is firmware? What is Software? Photo by Kübra Doğu from Pexels Imagine, if you will, that you have no idea what to make for dinner today. Luckily, you find an old cookbook you have and decide to cook one of the recipes in it. The cookbook has many recipes. Each of these recipes has its own instructions. In the cookbook, a recipe can be seen as a set of steps (or instructions) that together make a meal. Photo by You can also create your own meals based on your experience in cooking many different recipes, right? Software is no different. Software programs can be seen...

Hardware Is Physical: It's "Real," Sometimes Breaks, and Eventually Wears Out Hardware is "real stuff" that you can see with your eyes and touch with your fingers. And being a physical item, you can also sometimes smell it as it dies a fiery death, or hear as it physically decays in its last motions. While it's not always this easy, using one of your five senses—except taste; please don't taste any part of your computer system—is often your best way to tell if the hardware is the cause of a problem. Is it smoking? Is it cracked? Is it missing a piece? If so, the hardware is probably the source of the concern. Software is also extremely flexible, allowing it to be continuously updated and modified. While you certainly wouldn't expect your wireless router to "grow" another antenna or your smartphone to get a bigger screen as it charged on your nightstand, expect your software to regularly gain features and grow in size as it's updated. Another great thing about software is its potential to last indefinitely. So long as the software is copied to newer hardware before the current device fails, the information itself could exist as long as the universe does. Equally amazing is that software can be destroyed. If there are no copies, and the software is deleted, it's gone forever. You can't run to the store and pick up a replacement for information that never existed anywhere else. Troubleshooting a software problem is usually more complex than working through a hardware one. Har...
