mp3 player often because the procedure bug, or a variety of small failures, users gradually its shortcomings and the lack of functional complain, is not a complete solution . Now here is the solution  the problem of player firmware upgrade Theory and Practice of the article.
First, theoretical articles

1,what is firmware

 First of all  the intent of the firmware,  perhaps you had used mp3 and many other electronic products.  the most basic, in the firmware, from the translation software is a function of the hardware, in the past such devices are generally there are software EROM or EPROM, and usually kept by the hardware in the Procedures can not be direct users to read out or modified, usually a number of small problems there was no need to amend or upgrade the firmware, even if the firmware is found in a serious Bug, must also be written by professionals with the procedures EPROM The original machine to replace the EPROM down. Here, we will certainly be a bit confused, asked, in the end firmware is hardware and software? » Back to today, the firmware is a type of software, but software too deep too wide meaning, where the software firmware which means that the meaning of a system in the bottom of the most basic work of software known as firmware .

2, the importance of firmware

After reading the above paragraph explanation, readers of the firmware (the most basic systems in the bottom of the software) the basic principles of the meaning is clear. With the preliminary understanding of the firmware, now in the firmware on to talk about the importance of players. In addition to the hardware player in the circuit board is firmware (software), and players in the function of strong or weak, the quality of both audio and firmware are closely related to the contact. So, the player with a high-quality hardware is not enough, we must also with a set of high-quality firmware, which can match more high-quality hardware to give full play to the best effect, or around very easily cause an imbalance The lame phenomenon. Such as: Hyunwon in 2000 launched a "moon Baohe" the player, but in the market not long, found on board because of the PCB design problems caused by malfunctioning keys, the problem is widespread. On the past, many developers will take measures to return the way to deal with this issue. Hyunwon company but did not do so, in principle after its firmware of further changes to the advantage of the revised firmware to make up for the deficiencies in hardware and inadequate, after the issue be resolved quickly, this event will such a Success . In view of this, the importance of hardware and firmware is absolute, equal, one can not do, but in certain circumstances firmware can also compensate for the deficiencies on the hardware and inadequate, so the more players in the firmware For the importance of.

3, why should upgrade the firmware

The firmware upgrade also addressed the above reasons, also equivalent to further revise and improve procedures firmware, speaking before the player is a hardware problem with the firmware upgrade to improve. No problem that the player can be upgraded » No Problem! They can upgrade the firmware the same procedures to improve the function of players, audio players make better, more powerful. Especially in today's era of rapid development of information technology, and constantly improve people's living standards, the requirements of digital products is also increasing, extraordinary product features far failed to meet their needs. Therefore, the developers are actively developing a better player firmware procedures to prepare for the needs of players. Now, we have not had trouble professionals, music enthusiasts and gamers can easily get at home firmware upgrade.

4, the benefits of solid upgrade

Why firmware upgrade then by the audience and developers are concerned about it » The author of the following benefits!

5, upgrade Principle

The current market players, most of them will be stored in FLASH firmware chip, is now a popular gradually. Having said that, readers are probably also on the principle of upgrading to understand, is to revise and improve the firmware via the USB data output layer to cover FLASH chip on OK. However, players of different chips and some on the principle of distinction, made after the failure of the upgrade will appear in the handling of two situations: the first is to use an independent USB data transmission chip MP3, the chip does not need the support of firmware , With this chip player in the upgrade process relatively simple, high security, simply revise and improve the firmware via the USB data transmission sent to the FLASH-chip to the second is the work of USB chip Need firmware support, upgrade the firmware upgrade process not only the main chip procedures, but also upgrade the USB chip control procedures Although the upgrade process and a similar, is a complex, high-risk a point, once the upgrade fails, Even with the outside world may have data transmission USB ports will lapse. But please be assured that I will be following on a solution for everyone.

6, before the necessary upgrading work

Firmware upgrade because there are certain risks, in order to minimize the troubles and losses. Following is a summary of the points we must work before upgrading to prevent unnecessary accidents, take the following points, upgrade the success rate will be higher.

Sufficient battery power to prevent the escalation of the process of battery power due to a lack of disruption, leading to escalation of failure.
Backup the original firmware, can prevent the escalation of errors or are not satisfied with the new firmware, moved back to the original version.
The new firmware file, although most products can upgrade the network directly, but to download to your computer to upgrade the reliability will be higher.
Shut down the computer running the software, in order to prevent escalation of the interference by other software, the best temporary closure of unwanted software, in particular antivirus software.
Check whether the USB interface normal, preferably before upgrading to upload or download a music file, testing the reliability of the USB interface.
Empty players not relevant data, in order to prevent escalation, due to insufficient capacity Flash upgrade caused the failure.

7, after the failure of the upgrade to do

Upgrading the course of what the accident did not occur, generally successful upgrade. But this is only the general case, said this to say, there are still many users of the audience experienced the pain of defeat. Below the author after the failure of the two summed up the situation and the common people of review, due to more types of market players, also requested on incomplete understanding.

(1) after the failure can be found in hardware player

Such a situation the player's USB cable in general it does not rely on firmware procedures, or that the two are independent, such players after the failure of escalation is relatively easy to resolve, first of all should be upgraded to an analysis of the failure of Reasons, most cases are in the player still has music files to upgrade the circumstances of this failure may be, or upgrade some of the causes of accidents were caused by interruption. The solution is very simple methods, because the computer can still find players, according to analysis from January 1 to resolve the causes, and then an upgrade to solve. For example, if the player is also stored on a relatively large number of music files, you can try a player format, if a particular application because of the disruption caused by, first application to stop further escalation of time. In short, because the escalation of players after the failure of the USB cable has not been interrupted, the remedy is very easy.

(2) can not be opened after the failure of machinery, computer hardware can not find players

Comparing this situation generally trouble, because then the normal way the computer is unable to communicate with the players, so it is not possible to upgrade the player. But this is not to say that this player did not save, you will be sent to the players before the repair station may wish to try my method. Players will access the computer's USB and press the start-up key players (the majority of products for the Play button) to more than 4 seconds, the computer will then general report found new hardware, but the show is not the players, but the main players Chip models, then immediately open the player's management procedures, or special upgrade tools, sometimes special tool player makers do not directly provide, you can look at the CD player provided by the CD-ROM with no other ancillary procedures, General management procedures will be immediately identified the wrong player firmware, and will be temporary load through the USB firmware to the chip to memory and then chip will automatically restart the computer and find the players, then that is not Players have been normal, because only temporary through firmware loaded into the chip, but a power, firmware will disappear, so should immediately use management software or special tools to upgrade the firmware updates.


Second, combat chapter

Solution to the practice examples:

Said a lot of theory and practice will also少不了the operation, in order to better understand all players firmware upgrade process. Below we took it for a player to be a firmware update is gymnastics, with the player users should not miss!

Take the most popular here a player IRIVER iFP-380T as experimental products.此款iFP-380T used in a separate dedicated USB chips, data transmission of the firmware from the impact of procedures, so, iFP-380T even if the upgrade process is a failure, the problem will not be great, USB data transmission to the same level Normal work. As long as the good memories of the upgrade of the problems, to correct serious again. The results must be successful, the following will use IRIVER iFP-380T readers for a demonstration of the upgrade. Once again reminded, think about upgrading before the preparatory work are not doing a good job, a very important! In fact, iRiver firmware as there is a public beta version of 2.10 G, however, iFP-3xxT series only 8 MB firmware storage space, one can not support all music formats, each firmware version and the need to MP3/WMA/ASF MP3/OGG version of the choice, this version only supports Ogg Vorbis audio format, does not support WMA and ASF files.

Overview:

Upgrade here, the above is a success story of the upgrade process, we all see, is not very simple? Just a few steps to get the firmware upgrade, you will love for the former it is not, its meaning also will be more powerful with the rich. Generally speaking, if you love for the USB data transfer for the chip is an independent, for your love of escalation can not to worry. Another is the USB data transfer is dependent on the chip firmware procedures, in this case, if the upgrade did not successful, processing more than trouble. There are certain risks, Nongbu Hao will be more slots, have said that in theory, which will not repeat. Hope that the above theory and practice of a combination of articles for you to solve the problem. But rest assured that in this rapid development of electronic technology today, the escalation of the failure of the deficiencies or else how long will certainly be satisfactorily resolved, then, the firmware upgrade process will be easy,everybody can play it in the palm of !
