For example, if the remaining storage space on the startup section 32a can no longer store drivers for USB devices or other file systems, when the user needs to upgrade the application program section 31a of the electronic product, then Unable to use USB devices or upgrade via the Internet, the user must send the electronic product to the repair shop, and ask the repair shop to handle it, which is very inconvenient for ordinary users
[0004] However, the storage space of the application program section 31a is often configured with a larger storage space (usually several Mbytes), but it is not fully used. Therefore, it is necessary to provide a method for updating the program section, using the storage space of the application program section Space to improve the shortcoming that the storage space of the startup section is too small

The invention provides a method for updating a program segment. Specifically, the method for updating a program segment is used for an electronic system, and a processor and a storing device are comprised, wherein the processor is electrically connected with the storing device; the storing device comprises a program segment; and the program segment comprises an application program segment and a starting segment. The method for updating the program segment comprises the following steps of: installing a first start loading program in the application program segment, wherein the first start loading program comprises execution of a first drive program; connecting a data source device, wherein the data source device comprises updating data; judging whether the first drive program can drive the data source device or not; and when the first drive program can drive the data source device, executing an updating program according to the updating data. The method of the invention for updating the program segment can overcome the defect of undersize storing space of the starting segment by utilizing the storing space of the application program segment.
Description
technical field [0001] The present invention relates to a method for updating program sections, in particular to a method for enabling boot loader to support more data source devices. Background technique [0002] The storage space of the startup section of the microprocessor on the existing electronic products cannot accommodate too many functions and hardware drivers due to configuration limitations. [0003] Such as figure 1 as shown, figure 1 In the prior art, the configuration of the program section 30a of a storage device, the program section 30a includes the application program section 31a and the startup section 32a, under the setting of the prior art, the application program section 31a is during the update period It is impossible to execute other programs, so the startup program is always set in the startup section. Since the storage space of the boot section 32a is extremely small (usually a few Kbytes), the boot section 32a can only store few programs or data....
