Description

Electronic device and system updating method thereof

The present invention relates to a system updating method, and more particularly to a system updating method for an electronic device.

In the early consumer handheld devices, the firmware was burned in an Electrically Erasable Programmable Read-Only Memory (EEPROM; EEPROM, NOR Flash), and then directly guided by the CPU. The content of NOR Flash is imported into memory (memory) for execution. Once there is a problem with the system, the handheld device is reset, and the contents of the NOR Flash are reloaded into the memory to restore the function.

However, with the development of multimedia and network technologies, the size of the system is growing. Under the cost of consideration, it is not a very realistic practice to burn the system into expensive NOR Flash. Therefore, more and more system configurations are divided into two parts: the bootloader and the operating system (OS): the boot program and some debugging or diagnostic programs are burned to the NOR Flash, and the operating system is burned. Record relatively inexpensive mass storage media such as NAND Flash or hard disk (HDD). When the handheld device is powered on, the CPU boots from the NOR Flash and then executes a boot program to drive the basic device, such as memory, display panel, NAND Flash or hard drive. Thereafter, the operating system stored in the mass storage medium is loaded into the memory for execution.

As user levels increase, more and more users need to perform custom operations on the device's system, such as upgrading new systems or installing new software, but at the same time bringing more and more risks. At present, the update procedure of the system of the handheld device is generally as follows: 1. After preparing the upgrade file, connect the product to the computer to make the product enter the upgradeable mode; 2a. If the product system is placed on a large-capacity storage medium, copy the upgrade file to the product's large-capacity storage medium through a specific software. After leaving the computer, the upgrade file is read from the large-capacity storage medium to the memory, and then the program is run from the memory to start updating the contents of the large-capacity storage medium; 2b. If the product system is placed with the NOR Flash, through the specific The programming program can directly update the content of the NOR Flash; 3. After the upgrade is completed, the content of the system is generally read by the Reset action to complete the update.

The risk of upgrading the system is that during the upgrade period, the product is not allowed to have a power outage. It is especially important for products stored in NOR Flash, because Flash needs to erase the content and then write it. Once the writing process is interrupted, the content of Flash will be incomplete, so the product will not boot. Unit), there is no special way to recover.

For products stored on large-capacity storage media, updating the boot program in NOR Flash becomes a key part. Although the update time has been greatly shortened, there are still risks. Once the content of NOR Flash is lost, the product will also fail to boot. However, if only the content of the mass storage medium is lost, you can restore it by re-installing the contents of the large-capacity storage medium by entering the special mode of the system through the boot program in NOR Flash.

Basically, new software installed on consumer handheld devices is placed in mass storage media. The disadvantage of installing software is that although such software generally only updates external storage components, it generally does not occur that the system cannot be started. However, those software used to set up a personalized system, if improperly installed System errors can occur when the system files are closed, especially for the Windows Mobile system of smart phones. In the event of a system error, the average user may not be able to enter a special mode to achieve system recovery, because the operation will be very challenging for non-professionals.

At present, computer products still need a lot of system maintenance, and with the complexity of the system and the advancement of multimedia networks in the future, consumer handheld devices are likely to face maintenance problems similar to current computer products.

In an actual application, the electronic device according to the present invention may be a mobile phone, a personal digital assistant (PDA), and a multimedia player (such as an MP3 player), but is not limited thereto.

Once there is a problem with the system of the electronic device, the user can return the system to the normal state by following the instructions and pressing the prescribed button. Therefore, according to the present invention, the user does not need to resort to the help of a professional maintenance person, and does not need to find a solution on the Internet, as long as the "one-click recovery" can effectively prevent the failure of the electronic device. Two examples are listed below to fully illustrate the concept of the invention.

First specific embodiment:

Please refer to Figure 1, Figure 3A to Figure 3C. 1 is a functional block diagram of an electronic device 1 according to a first embodiment of the present invention. FIG. 3A and FIG. 3B are diagrams showing the normal startup process of the electronic device 1 of the first embodiment. flow chart. FIG. 3C is a flow chart showing a system updating process of the electronic device 1 of the first embodiment.

As shown in FIG. 1, the electronic device 1 includes a main updatable storage medium 10, a first slave renewable storage medium 11, a second slave renewable storage medium 12, a processing unit 13, a data storage unit 14, and a system repair unit. 15. The processing unit 13 is coupled to the primary updatable storage medium 10, the first slave updatable storage medium 11, the second slave updatable storage medium 12, the data storage unit 14, and the system repair unit 15, respectively.

In practical applications, the primary updatable storage medium 10, the first slave updatable storage medium 11, and the second slave updatable storage medium 12 may all be a NOR flash memory (NOR Flash). The data storage unit 14 can be a NAND flash (NAND Flash), a hard disk or an external storage device (such as a memory card).

The primary updatable storage medium 10 stores an existing system data 100, and the data storage unit 14 stores backup data 140 of the current system data 100. In this embodiment, the current system data 100 can include a bootloader and an operating system (OS). In practice, the backup data 140 in the data storage unit 14 can be set to be read only when the electronic device 1 enters the system restore mode.

The first slave updatable storage medium 11 and the second slave updatable storage medium 12 do not require a large amount of storage. In this embodiment, the present invention uses two first and second slave renewable storage media 11, 12 each having a size of 16 KB as an example. Because NOR Flash is expensive, using multiple blocks is not only wasteful but also causes an increase in cost. In addition, low-capacity NOR Flash also minimizes costs.

As shown in FIG. 1, the first slave renewable storage medium 11 and the second slave The updateable storage medium 12 stores the first boot code 110 and the second boot code 120, respectively, which can be copied from the boot program stored in the main updatable storage medium 10. Therefore, the electronic device 1 of the present invention can be started by the processing unit 13 by booting the booting program through the boot code of one of the first and second slave-updable storage media 11, 12.

As shown in FIG. 3A, the normal startup of the electronic device 1 first executes step S100 to boot the booting program. Next, step S102 is performed to drive a basic device such as a display panel, a NAND Flash or a hard disk. If the normal startup process is successful, step S128 is finally performed, and the processing unit 13 loads and drives the operating system from the main updatable storage medium 10.

When the system of the electronic device 1 is to be upgraded, the contents of the upgrade file are read into the electronic device 1, and then loaded into the memory to perform an update process, as shown in FIG. 3C. Step S200 is executed to update the content of the first dependent updateable storage medium 11. Step S202 is executed, and the processing unit 13 determines whether the first dependent updateable storage medium 11 is successfully updated. It should be noted that, if the first slave updateable storage medium 11 is updated, the processing unit 13 may preset to first boot the boot program through the second slave updateable storage medium 12.

The first slave updateable storage medium 11 includes N data sectors, and the step S200 is updated from the kth data sector until each data sector is updated, where N is an integer, k It is an integer between 1 and N. In this embodiment, step S200 may first write an update information (for example, write "UPDATING") or keep blank in the first data section, and write update data from the second data section to the Nth. After the data section is written, the update data is written into the first data section to complete the update of the first slave updateable storage medium 11.

If the power failure fails due to the power failure, the determination result of step S202 will be NO, and then return to step S100. When proceeding to step S104, the processing order The element 13 determines whether the first data section of the first slave updatable storage medium 11 has "UPDATING" information or remains blank. If so, the processing unit 13 performs step S106 to copy the second slave updatable storage. The content of the medium 12 is replaced by the content of the first slave renewable storage medium 11 and then restarted, and then step S200 is performed again.

If the result of the determination in step S202 is YES, the processing unit 13 may further perform step S204 to check whether one of the updated first dependent updateable storage media 11 is the same as the first target check code. If yes, step S206 is performed to update the content of the second slave updateable storage medium 12; if not, step S200 is repeated. After step S206, the processing unit 13 performs step S208 to determine whether the second dependent updateable storage medium 12 is successfully updated.

If the result of the determination in step S208 is no, step S210 is executed to trigger the system repair unit 15, and then the electronic device 1 is actuated through the first slave updateable storage medium 11, and then step S206 is performed. In practical applications, the system repair unit 15 can be implemented as a button, and a trigger signal is generated to the processing unit 13 if the button is pressed.

As previously described, since the processing unit 13 presets to boot the boot program through the second slave-updable storage medium 12, if the update process fails, the electronic device 1 will fail. At this time, the user can trigger the system repair unit 15 (ie, press the corresponding button), so that the processing unit 13 turns the second slave renewable storage medium 12 again after booting the boot program through the first slave renewable storage medium 11. . Functionally, system repair unit 15 is used to switch the boot route between two slave renewable storage media.

After the second dependent updateable storage medium 12 is successfully updated, the electronic device 1 is automatically restarted. In step S108, the processing unit 13 further checks whether the first check code in the updated first dependent updateable storage medium 11 is The second check code is the same as one of the updated second dependent updateable storage media 12. If not, the processing unit 13 performs step S110 to copy the content of the first slave updateable storage medium 11 to replace the content of the second slave updateable storage medium 12, in order to prevent the second dependent updateable storage medium 12 from being The content is incorrect and cannot be started properly.

If the result of the determination in step S208 is YES, step S212 is performed to replace and update the current system data 100 by copying an updated system data into the main updatable storage medium 10. Then, step S214 is executed, and it is determined by the processing unit 13 whether the primary updatable storage medium 10 is successfully updated. It should be noted that the update manner of the second slave renewable storage medium 12 and the primary updateable storage medium 10 may be the same as that of the first slave updateable storage medium 11, and details are not described herein again. If the result of the determination in step S214 is YES, the update procedure of the electronic device 1 is completed.

If the decision result in the step S214 is NO, the electronic device 1 will also be invalid. At this time, step S216 is performed to trigger the system repair unit 15 and the startup process is restarted. When the process proceeds to step S112, the processing unit 13 determines whether the primary updatable storage medium 10 is currently to be updated. If yes, step S114 is executed, and the processing unit 13 checks whether the "UPDATING" information appears in the main updatable storage medium 10 or remains blank. If so, the processing unit 13 copies the backup data 140 from the data storage unit 14 to the main updatable storage medium 10 to replace the current system data 100. After restarting the electronic device 1, step S212 is performed again.

In addition, if the result of the determination in step S114 is negative, the processing unit 13 may further perform step S116 to check whether one of the updated primary updateable storage media 10 is the same as one of the backup data 140. If not, the processing unit 13 performs step S120 to copy the updated system data to the data storage unit 14 to replace and update the backup data 140.

If the result of the determination in step S112 is negative, the processing unit 13 may further perform step S122 to determine whether it is the repair mode. If yes, the processing unit 13 copies the backup data 140 from the data storage unit 14 to the main updatable storage medium 10 to replace the current system data 100, and then restarts the electronic device 1; if not, the processing unit 13 can further perform step S124. And checking whether the first check code in the updated first dependent updateable storage medium 11 is the same as the second check code in one of the updated second dependent updateable storage mediums 12.

If the result of the determination in step S124 is no, the processing unit 13 executes step S126 to copy the content of the second slave updateable storage medium 12 to replace the content of the first slave updateable storage medium 11 and restart the electronic device 1. To ensure that the contents of the first and second slave renewable storage media 11, 12 are the same, they are all updated to the latest version; if so, the processing unit 13 executes step S128 to load and drive the operating system.

Second specific embodiment:

The first slave updateable storage medium 21 and the second slave updateable storage medium 22 respectively store the first boot code 210 and the second boot code 220.

Primary updatable storage medium 20, first slave renewable storage medium Both the 21 and the second slave renewable storage medium 22 can be a NOR flash memory. The data storage unit 24 can be a NAND flash memory, a hard disk or an external storage device (such as a memory card).

The primary updatable storage medium 20 stores the first current system data 200. The data storage unit 24 stores the second current system data 240, the first backup data 242 of the first current system data 200, and the second backup data 244 of the second current system data 240. It should be noted that the first current system data 200 in this embodiment is a booting program, and the second current system data 240 is an operating system.

Similarly, when the system of the electronic device 2 is to be upgraded, the content of the upgrade file needs to be read into the electronic device 2, and then loaded into the memory to perform the update process, as shown in FIG. 5A to FIG. Basically, the update process of the primary updatable storage medium 20, the first slave updatable storage medium 21, and the second slave updatable storage medium 22 in this embodiment is the same as that of the first embodiment, and FIG. 5A The flowchart of FIG. 5B increases the update flow of the second current system data 240 and the second backup data 244 stored in the data storage unit 24.

If the result of the determination in step S414 is YES, step S418 is executed to copy the second updated system data to the data storage unit 24 to replace and update the second backup data 244. Thereafter, the processing unit 23 performs step S420 to determine whether the update is successful. If not, step S418 is repeated; if so, processing unit 23 may further perform step S422 to check whether one of the updated second backup data 244 is the same as a target check code. If the result of the determination in step S422 is no, the process returns to step S418; if so, step S424 is executed to copy the second updated system data to replace and update the second current system data 240. The update process of the second current system data 240 is the same as the above-mentioned NOR flash, and will not be described again here.

Next, step S426 is performed to determine whether the update is successful. If yes, the update procedure of the electronic device 2 is completed; if not, the electronic device 2 is automatically restarted. In addition to determining whether to repair the primary updatable storage medium 20 in step S322, to step S328, the processing unit 23 may determine whether to repair the second current system data 240 in the data storage unit 24. If the system repair unit 25 is triggered, the processing unit 23 performs step S330, copies the second backup data 244 to replace the second current system data 240, and then restarts, and then proceeds to step S424; if not, the processing unit 23 performs steps. S332, loading and driving the operating system from the data storage unit 24.

In summary, the electronic device according to the present invention only needs to restore the electronic device from the abnormal state to the normal state by using a system restore button, thereby improving the reliability of the product and the convenience in use. In addition, for manufacturers, as long as the hardware cost and design space are slightly increased, the product repair rate can be greatly reduced.
