Description
METHOD FOR BOOTING AN EMBEDDED DEVICE
FROM AN EXTERNAL USB DEVICE
TECHNICAL FIELD OF THE INVENTION
The present invention relates generally to a method for booting an embedded device, and more particularly to a method for booting an embedded device by using an external USB device.
BACKGROUND OF THE INVENTION
In a normal situation, an embedded device boot up by loading existing kernel, file system, and configuration file, which are stored within an internal storage of the embedded device. The embedded device is required to be updated with new firmware, new configuration file, or both from time to time for the purposes of debugging, maintenance, and management of the embedded device, such as updating the firmware to enhance the capability of the device or just to fix some bug issues.
Typically, such actions are carried out by a certain user who knows the existing configurations of the embedded device, such as the IP address, service set identifier (SSID), username, and password of the embedded device. This is where problems occur. For example, the embedded device cannot be accessed by people who does not know the existing configurations, or when the username and password are forgotten. At time like this, a user is forced to reset the embedded device to factory default settings so that he or she is able to access and boot the embedded device. This solution is not the best because all the existing configurations will be erased and further settings have to be done to the embedded device. Alternatively, the user is able to access the embedded device by performing serial cable connection. While this alternate solution preserves the existing configurations, it requires the user to physically handle the embedded device, and involves messy cables, all of which are tedious, time consuming, and require great effort.
Therefore, it has become an aim of the present invention to introduce a method for booting an embedded device by using an external USB device without knowing the IP address, SSID, username, password, or a combination thereof of the embedded device.
SUMMARY OF THE INVENTION
The core technical aspect of the present invention is directed to a method for booting an embedded device, such as a wireless access router, by using an external USB device, such as an external USB flash drive, in a circumstance where the IP address, service set identifier (SSID), username, password, or a combination thereof of the embedded device is unknown to a user.
The said method comprises a first step of having the embedded device to detect the presence of the external USB device, i.e. whether the external USB device is connected to the hardware of the embedded device, which preferably may be performed by a universal boot loader (U-boot) of the embedded device; a second step of having the embedded device to verify the external USB device, i.e. to confirm the authenticity of the external USB device, wherein the verification process preferably may be a key exchange mechanism; a third step of booting the embedded device via the external USB device by having the embedded device to detect and load the second kernel, second file system, and second configuration file of the external USB device; a fourth step of having the external USB device to set the IP address, SSID, username, password, or a combination thereof of the embedded device to default; a fifth step of having the external USB device to scan the hardware of the embedded device; a sixth step of having the external USB device to list out, according to the scanning results of the fifth step, at least one new firmware that is related to the hardware of the embedded device, at least one new configuration file that is related to the hardware of the embedded device, or a combination thereof; and a seventh step of viewing the existing configuration of the hardware of the embedded device, updating the existing firmware of the hardware of the embedded device with the listed out new firmware, updating the existing first configuration file of the hardware of the
embedded device with the listed out new configuration file, or a combination thereof.
In the event where the external USB device manages to list out one new firmware or one new configuration file that is related to the hardware of the embedded device, the existing firmware or the existing first configuration file of the hardware of the embedded device will be automatically updated with the listed out new firmware or the listed out new configuration file, respectively, upon booting.
In the event where the external USB device manages to list out one new firmware and one new configuration file that are related to the hardware of the embedded device, the existing firmware of the hardware of the embedded device will be updated with the listed out new firmware prior to updating the existing first configuration file of the hardware of the embedded device with the listed out new configuration file.
In the event where the external USB device manages to list out more than new firmwares, more than one new configuration files, or a combination thereof that are related to the hardware of the embedded device, the user will be able to choose which listed out new firmwares to be used to update the existing firmware of the hardware of the embedded device, which listed out new configuration file to be used to update the existing first configuration file of the hardware of the embedded device, or a combination thereof via a remote debugging screen.
BRIEF DESCRIPTION OF THE DRAWINGS
Figure 1 illustrates the elements that are involved in the method of the present invention for booting an embedded device by using an external USB device; and
Figure 2 is a flow chart depicting the method of the present invention.
DETAILED DESCRIPTION OF THE INVENTION
The above mentioned and other features and objects of this invention will become more apparent and better understood by reference to the following detailed description. It should be understood that the detailed description made known below is not intended to be exhaustive or limit the invention to the precise disclosed form as the invention may assume various alternative forms. On the contrary, the detailed description covers all the relevant modifications and alterations made to the present invention, unless the claims expressly state otherwise.
The main aspect of the present invention relates to a method for booting an embedded device (100) by using an external USB device (200). The unique feature about this particular method is that a user is able to boot the embedded device (100) for the purposes of debugging, management, and maintenance of the embedded device (100) without the need to know the IP address, service set identifier (SSID), username, password, or a combination thereof the embedded device (100). Conventionally, in the condition where the IP address, SSID, username, password, or a combination thereof of the embedded device (100) is unknown to the user, the user is only able to access and boot the embedded device (100) by resetting the embedded device (100) to factory default settings. This is an undesirable action as the existing configurations of the embedded device (100) will all be wiped out, and additional setting action will have to be taken after accessing the embedded device (100). The other way to access and boot the embedded device (100) while preserving the existing configurations is to perform serial cable connection. While this is more advantageously than the previously discussed technique, it is still unfavourable as it requires the user to physically handle the embedded device (100) such as dismantling the embedded device (100) in order to access the hardware part, and involved messy cables, all of which are tedious, time consuming, and require great effort.
All of the aforementioned disadvantages are not present in the method as described herein.
The details of the present method will now be thoroughly discussed with the aid of Figure 1 and Figure 2. Two core devices are involved, namely the embedded device (100) such as a wireless access router, and the external USB device (200) such as an external USB flash drive.
Within the embedded device (100), it comprises several other elements, namely a universal boot loader (U-boot) (101), a first kernel (102), a first file system (103), and a first configuration file (104), whereas within the external USB device (200), it comprises several other elements, namely a second kernel (202), a second file system (203), a second configuration file (204), at least one new firmware (300) that is related to the hardware of the embedded device (100), and at least one new configuration file (400) that is related to the hardware of the embedded device (100).
The method comprises the initial step of having the embedded device (100) to detect for the presence of the external USB device (200) (701), i.e. whether the external USB device (200) is connected to the hardware of the embedded device (100).
Upon detecting that the external USB device (200) is present, the embedded device (100) will verify the external USB device (200) in order to confirm the authenticity of the external USB device (200) (702). The verification process can be of any known verification process. In one embodiment of the present invention, the verification process is a key exchange mechanism. Soon after the verification process, the embedded device (100) proceeds to detect and load the second kernel (202), the second file system (203), and the second configuration file (204) in order to boot the embedded device (100) via the external USB device (200) (703). The aforesaid detection and loading action are performed by the U-boot (101) of the embedded device (100). Referring to Figure 1 , it can be
seen that the embedded device (100) and the external USB device (200) are connected to each, and the connection is represented by the bi-directional arrow.
Subsequently, the external USB device (200) set the IP address, SSID, username, password, or a combination thereof of the embedded device (100) to default (704). In other words, at this point, it is not necessary for the user to know the IP address, SSID, username, password, or a combination thereof of the embedded device (100). At this point, the external USB device (200) scans the hardware of the embedded device (100) (705) in order to determine and list out at least one new firmware (300) that is related to the hardware of the embedded device (100), at least one new configuration file (400) that is related to the hardware of the embedded device (100), or a combination thereof (706). The user will then has the options of viewing the existing configuration of the hardware of the embedded device (100) (707), update the existing firmware of the hardware of the embedded device (100) with the listed out new firmware (300) (708), updating the existing first configuration file (104) of the hardware of the embedded device (100) with the listed out new configuration file (400) (709), or a combination thereof.
In the circumstance where the external USB device (200) only manages to list out one new firmware (300) or only one new configuration file (400) that is related to the hardware of the embedded device (100) (706), the existing firmware or the existing first configuration file (104) of the hardware of the embedded device (100) will be automatically updated with the listed out new firmware (300) or the listed out new configuration file (400), respectively (708) (709), upon booting. In the circumstance where the external USB device (200) manages to list out one new firmware (300), and one new configuration file (400) that are related to the hardware of the embedded device (100) (706), the existing firmware of the hardware of the embedded device (100) is prioritized to be updated first with the
listed out new firmware (300) (708) before the existing first configuration file (104) of the hardware of the embedded device (100) is updated with the listed out new configuration file (400) (709). In the circumstance where the external USB device (200) manages to list out more than one new firmwares (300), more than one new configuration files (400), or a combination thereof that are related to the hardware of the embedded device (100) (706), the user is able to choose, via a remote debugging screen, from the listed out new firmwares (300) which version of new firmware (300) is to be used to update the existing firmware of the hardware of the embedded device (100) (708), from the listed out new configuration files (400) which version of new configuration file (400) is to be used to update the existing first configuration file (104) of the hardware of the embedded device (100) (709), or a combination thereof.
