Problems solved by technology

However, if the embedded Linux system is completely damaged or cannot be connected to the computer, the flashing operation cannot be conveniently performed, and it needs to be returned to the factory for repair or disassembled and then flashed.

Embodiment Construction

[0012] The technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0013] Now most of the embedded Linux systems can be started through SD cards, but due to the slow access speed and pluggable characteristics of SD cards, the final Linux system generally does not run on SD cards, but runs on On the solid-state memory on the PCB board. The consequence of doing so makes it inconvenient to refresh the Linux system. Through the present invention, the flashing program and the mirror image for flashing can be written on the SD card, and the system software on the solid-state memory on the PCB is refreshed by starting from the SD card, so that the flashing operation is greatly simplified.

[0014] Such as figure 1 Shown, the invention provides a kind of embedded Linux operating system to start the making method of SD card, and it comprises the following steps:

[0015] S1, according to figure...

Abstract

The invention relates to a manufacturing method of an embedded Linux operating system starting SD card. The method includes the following steps that the SD card is planned before partitioning according to a mirror image and a partition distribution diagram, and a plurality of sectors and an FAT32 partition are obtained through planning; the SD card is inserted into a computer provided with a Linux operating system to be subjected to partitioning, and the FAT32 partition is marked out through an FDISK partitioning tool and is formatted; a mirror image document essential for running of the embedded Linux operating system on the SD card is programmed to the SD card according to a command provided by the Linux operating system; various mirror image documents needing to be refreshed into a solid-state memory are copied to the FAT32 partition. The starting SD card manufactured through the manufacturing method can be used for conveniently performing flash operation under the condition that the embedded Linux operating system is thoroughly damaged or conditions for computer connection do not exist.

Description

technical field [0001] The invention belongs to the technical field of computers, and in particular relates to a method for making an SD card for starting an embedded Linux operating system. Background technique [0002] A typical embedded Linux hardware system uses solid-state memory such as flash memory welded on the PCB board to save various image files and file systems required for the startup of the embedded Linux operating system. If the embedded Linux system breaks down, or the entire software system of the embedded Linux needs to be upgraded, it is necessary to re-program the various image files and file systems that the embedded Linux operating system needs to start. The current common practice is to put the embedded device into the flashing mode, connect it to the computer through a data cable, and then flash it with special software. This requires that the embedded device can also enter the flashing mode and conditionally connect to the computer through the data ...
