Problems solved by technology

The system code is a code with important information. When the loading action of the system code fails, or an error occurs in the system code itself, the booting action of the electronic device will not be executed smoothly, or the operation of the electronic device will not work normally.
[0003] In the existing technical field, after the electronic device is packaged, the content of the system code cannot be modified
Therefore, when a system code error occurs or is not suitable for the operation of the electronic device, to correct the system code, the system code can only be corrected through more complicated actions, which requires high cost and time consumption.

Embodiment Construction

[0039] Please refer to figure 1 , figure 1 A flow chart showing a system code management method according to an embodiment of the present invention. Wherein, in step S110, the initial address of the non-volatile memory is initialized, and step S120 reads the first storage block of the non-volatile memory according to the initial address, wherein the code information and the first memory block are stored in the first storage block. Patch information. Here, the first storage block can be a block in a storage page in the non-volatile memory, and the non-volatile memory can be flash memory, or other forms of read-only memory (read only memory, ROM) . In the embodiment of the present invention, a storage page may be divided into four storage blocks. One of the storage blocks (for example, the first storage block) may have a default storage size for storing data, such as 4K bytes (Kbyte). In the first storage block, in addition to the 4K byte data space for storing data, there ...

Abstract

The invention provides a system code management device and a management method thereof. The system code management method comprises the following steps: initializing an initial address of a nonvolatile memory; reading a first storage block of the nonvolatile memory according to the initial address, wherein the first storage block stores code information and first repair data; and replacing the system code with the first repair data and obtaining a corrected system code.

Description

technical field [0001] The invention relates to a system code management device and its management method, in particular to a system code management device and its management method capable of repairing the system code. Background technique [0002] In today's electronic devices, the system code is usually stored in a non-volatile memory, and the system code is loaded during the booting process of the electronic device, and the booting action is executed according to the system code. The system code is a code with important information. When the loading action of the system code fails or the system code itself generates an error, the booting action of the electronic device will not be executed smoothly, or the operation of the electronic device will not work normally. [0003] In the existing technical field, after the electronic device is packaged, the content of the system code cannot be modified. Therefore, when the system code error occurs or the operation of the electr...
