Embodiment Construction

[0041] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0042] The embedded device updating method of the present invention comprises the following steps:

[0043] (1) Embedded device power-on detection step: Power on the embedded device and detect whether it is connected to a portable update device. When it is detected that a portable update device has been connected, use the automatic update mode and go to step (2) for processing, or use Partial update mode, go to step (3) for processing;

[0044] (2) Embedded device automatic update step: the portable update device automatically sends the u-boot update component program of the embedded device and th...

Abstract

The invention discloses an embedded device updating method and updating device, and belongs to the technical field of embedded device system updating, and the embedded device updating method comprises the following steps: electrifying an embedded device, detecting whether the embedded device is connected with a portable updating device, and when detecting that the embedded device is connected with the portable updating device, adopting an automatic updating mode or a partial updating mode; if the automatic updating mode is adopted, a u-boot updating component program of the embedded device and a system program of the embedded device are sent to a specified memory address of the embedded device; if yes, sending a u-boot updating component program of the embedded device or a system program of the embedded device or any subprogram in the system program of the embedded device to a specified memory address of the embedded device; and the embedded device checks and updates the received program or subprogram, and restarts the embedded device after storing the environment variable. According to the invention, the system updating difficulty of the embedded equipment is reduced, and the maintenance convenience of the embedded equipment is also improved.

Description

technical field [0001] The invention belongs to the technical field of updating embedded equipment systems, and more particularly relates to an updating method and an updating device for embedded equipment. Background technique [0002] u-boot is a kind of bootloader, which is used to boot and start the kernel. At present, most embedded devices have no display and no interactive devices during the startup process. In daily use, once the embedded device system needs to be updated or the system needs to be reprogrammed The kernel can be updated in the following three ways: carry a notebook, a programmer, and update it through a debugging cable and specific software tools; log in to the command line of the embedded device through a serial port to update manually; update the system through a U disk, SD card, or network. The first two methods mentioned above are complex and require operators to have certain debugging capabilities, which are not suitable for large-scale promotion;...
