The process of updating software is commonly referred to as firmware. Usually this method is used to make changes to the functional set of devices or to fix found errors in their operation.
Firmware is required for a device to perform certain tasks. This is a non-volatile piece of memory that contains information necessary for the correct operation of the microcontroller. Usually, firmware is done by installing a specific memory chip. Some hardware can be re-flashed. Naturally, this process is performed not by changing the microcircuit, but by changing the contents of its memory.
Modern devices are flashed mainly to correct various malfunctions. Errors found during the operation of the equipment are analyzed by specialists. Based on the information received, a new firmware is created to improve the quality of the device.
Sometimes firmware allows certain devices to perform different functions. For example, after flashing some older cell phones, it was possible to use their cameras to shoot videos.
Some devices are originally designed to work in a specific area. Changing the firmware helps to adapt the equipment to different operating conditions. Many manufacturers of network devices such as routers and switches advise updating their firmware before using the equipment in Russia.
Most often, new firmware is created by the manufacturers of certain devices. Sometimes firms develop special applications that allow you to quickly replace the firmware of a particular device. It is not uncommon to find equipment whose functions include the ability to update the firmware. This approach allows you to quickly correct the identified errors on your own, without contacting specialized centers. It is noteworthy that the firmware can affect not only the quality of the device, but also its performance.
