The method and the device can acquire the size of the target file corresponding to the target starting file in advance, determine the preset storage area according to the size of the target file, and control the target device not to perform formatting operation on the preset storage area when performing the flashing operation.
In this step, after the second preset storage address is obtained, the size of the target file may be obtained from the second preset storage area according to the second preset storage address.
S205, storing the size of the target file in the preset environment variable.
In this step, after the size of the target file stored in the preset storage area is obtained, the size of the target file may be stored in the preset environment variable, so that the target device may read the size of the target file from the preset environment variable when the target device is started next time. Illustratively, the value of the preset environment variable may be updated to the target file size.
S206, loading the target start file with the size of the target file from the preset storage area of the target device according to the first preset storage address.
The first predetermined storage address may be a start address of the first predetermined storage area.
In this step, after obtaining the size of the target file corresponding to the target boot file, the preset first preset storage address may be obtained, and the target boot file is loaded after obtaining the target boot file from the preset storage area according to the first preset storage address and the size of the target file.
And S207, running the target starting file to start the target equipment.
