What does it mean to brush the firmware?

Question 1: What does the firmware mean when you brush the machine? What you said is almost the same. Firmware is the system disk, which is also the C disk (popular explanation). The explanation of the specialty store is rom. The storage system of mobile phone consists of two parts, one is ram (which can be understood as memory stick), and the other is ROM (which stores the operating system of mobile phone, your business card, short messages and other materials). Some mobile phones also have an external memory card as extended memory. So you should understand.

Question 2: What does it mean to brush the firmware? Look at the definition of firmware. Firmware refers to the device "driver" stored in the device. Through firmware, the operating system can realize the operation of a specific machine according to standard device drivers. For example, both optical drives and recorders have internal firmware. Firmware is software solidified in hardware, and optical storage firmware is a software instruction set running on the driver, which stores the most basic parameters of hardware devices in the computer system and provides the lowest and most direct hardware control for the system. The firmware is similar in function to the BIOS on the motherboard. Similarly, in the boot process, the system will first read the initialization information of its internal hardware devices, so that the operating system can correctly identify the hardware and provide the most basic basis for the operation of other software. Some manufacturers will also store the data of various CDs on the market in firmware, mainly the data of burning CDs stored in the firmware of the burner. When burning, they will detect the information of the currently used optical disc, compare it with the stored data, and then adopt the corresponding burning method. Firmware is stored in hardware, and its storage media mainly include ROM, PROM, EPROM, EEPROM and Flash Rom. At present, optical storage products basically use erasable storage media to store firmware, which is convenient for users to refresh. Flash Rom is an improved nonvolatile storage medium based on EEPROM. When it erases data, it takes "block" as the unit, and the size of the block is determined by the manufacturer, while EEPROM erases data in bytes. Therefore, Flash Rom has faster erasing speed, advanced technology and convenient operation, which is very convenient for users to upgrade their own firmware. What kind of storage medium to use is often considered by equipment manufacturers according to the actual situation such as manufacturing cost, safety performance, whether it needs to be upgraded, and the development and change of equipment standards. The importance of firmware is self-evident, so it is necessary to upgrade with erasable media. Manufacturers can provide firmware upgrades to add more functions or improve its performance, or even correct its errors. Although some firmware problems can be remedied by software patches, it is not as reliable and convenient as upgrading firmware directly. Therefore, at present, when most manufacturers introduce hardware products, they all adopt the upgradeable firmware design to provide more flexible applicability. General optical storage manufacturers will provide necessary firmware upgrade programs, which can be downloaded directly from their official website. This kind of program has a small capacity, generally within 100 KB. Most firmware upgrade programs need to run in a pure DOS environment.

Question 3: What is the difference between brush system and brush firmware? There is little difference between firmware and system. Let's just say, for example, mobile phone upgrades, such as Android, push the system from 5.0 to 6.0. This is called a firmware upgrade. The system can be understood as Android 5.x, 6.x, etc., including third-party rom. Firmware is the platform for system upgrade. For example, Android 7.0 needs 6.0 firmware upgrade, but it cannot be upgraded from 5.0 firmware.

Question 4: What does firmware upgrade mean? It is to improve performance and fix the system and hardware vulnerabilities carried by the machine itself.

It usually solves some minor problems and brings some functional improvements. When downloading the firmware upgrade module, there will be corresponding instructions.

Suggestion: If there is nothing wrong with the machine, don't mention it.

Question 5: What is the difference between brushing firmware and brushing rom? Brush machine is to brush into new rom, so they are exactly the same concept, haha!

Question 6: What is the principle of firmware brushing? Firmware upgrade is not a download driver: please see below.

The firmware upgrade function has been increasingly written into the specifications of various players. For this familiar and unfamiliar function, many friends may have used it in a little knowledge, but they don't know the skills and details. In this article, I will take you to explore the secrets of firmware.

[What is firmware? ]

In the dictionary of firmware (FrimWar users), the explanation is hardware with software function. In the early days, such devices were usually EROM or EPROM with software, and the programs stored in these hardware could not be directly read or modified by users. At that time, there was generally no need to upgrade the firmware. Even if a serious error is found in the firmware, the EPROM on the original machine must be replaced by a professional with a program written on it. Does firmware refer to hardware or software? As we understand it now, firmware should refer to software. However, there are many kinds of software, not all of which can be called firmware. Generally speaking, the software that works as the most basic and lowest layer of the system can be called firmware. For example, we often say that the BIOS on the computer motherboard is actually called firmware by more professionals in the past.

[How important is firmware]

After understanding the basic principle of firmware, we can draw a conclusion that our understanding of firmware is "software that works at the most basic level of a system", and in the player, firmware is the soul of the player, because the player has no other software except firmware. So the firmware also determines the function and performance of the player. From this point of view, the firmware of the player is almost the same as its hardware status, and the firmware may be more important to some extent. Because only by writing excellent firmware programs can we give full play to the role of hardware more skillfully. One of the most famous examples is that Hyunwon Company introduced a player called "Moon Box" in 2000. However, it was not long before it was put into the market that the design problems of PCB led to the failure of keys, and the problem was very common. Traditionally, many manufacturers may take the way of recall to deal with this problem. However, after analyzing the principle, Hyunwon made a small modification to its firmware, and let the firmware fix this hardware problem. As a result, the incident quickly subsided. From this point of view, excellent firmware can also make up for some hardware defects here.

[Why should I upgrade the firmware]

Although it is called "firmware", it should be understood as software anyway. Due to the progress of integrated circuits, this firmware is based on Flash, and upgrading the firmware becomes easier and more dangerous. The difference between firmware programs and what we usually call programs is getting smaller and smaller. Early firmware upgrade is mainly to solve some bugs and compatibility problems. With the advent of the information age, it is difficult for manufacturers to fully meet the needs of customers. More manufacturers provide users with more updated functions as added value by upgrading firmware. Therefore, we can summarize the firmware upgrade as follows:

1. Solve existing bugs and compatibility problems.

2. Improve the operation mode to provide more convenient and humanized functions.

3. Provide more music format support.

[Promotion principle]

Because most players now save firmware in Flash, upgrading firmware is actually rewriting Flash with a new firmware program, but it can be divided into two ways according to the chip and principle. The first way is to use independent USB chip products, the most representative of which is the modern GDS30c600 1. For this kind of player, the upgrade is relatively simple and safe, just need to transfer the new firmware program to Flash through USB chip. The second is that USB is a part of the main chip, and the work also needs the support of firmware. The most representative one is iRiver 180TC (using Philips DSP chip). For this kind of player, the upgrade process is more complicated than before, and it is also dangerous, because once the update fails, even the most basic USB transmission function may be lost. Of course, for this kind of player, there is also a more flexible aspect, that is, the USB transport layer can be reprogrammed. This kind of player has the same process when dealing with the specific upgrade as the last one ... >>

Question 7: What is the use of wireless routing firmware? The firmware can improve the previous functions. Some of them may have more functions after brushing. For example, those who didn't have the speed limit function before can brush the firmware now, but this is only an example. This is the official way to upgrade the firmware. But if it is some prawns, it may change a lot. Usually we don't brush him for no reason. . Brush it. Maybe there is something wrong with this firmware now. Even though our general brushes are made of firmware from official website.

Question: What does it mean to refresh the firmware of iphone4s? What does firmware mean? Why brush the firmware? Mobile phone firmware is equivalent to mobile phone system, and refreshing firmware is equivalent to brushing the system. Different phones correspond to different firmware. Before brushing the firmware, fully understand the advantages and disadvantages and compatibility of the current firmware and the brushed firmware, and make full preparations.

Question 9: Take an Android phone as an example. What's the difference between a brush fastener and a brush system? It makes no difference. As far as I know, firmware refers to the mobile phone system!

Question 10: What does the firmware mean when you brush the machine? What you said is almost the same. Firmware is the system disk, which is also the C disk (popular explanation). The explanation of the specialty store is rom. The storage system of mobile phone consists of two parts, one is ram (which can be understood as memory stick), and the other is ROM (which stores the operating system of mobile phone, your business card, short messages and other materials). Some mobile phones also have an external memory card as extended memory. So you should understand.
