Example Embodiment
[0062] Example 1
[0063] Such as figure 1 As shown, it is a method for updating the logo of an embedded device at startup in accordance with this embodiment, which includes the following steps:
[0064] S1: Enter the logo update interface; this interface can be a sub-window of the main program of the embedded Linux device or an independent UI process. In this interface, the user can browse the picture files saved in the USB storage device and select the picture file.
[0065] S2: Read the picture file in the USB storage device, load the picture file list and display it on the logo update interface;
[0066] S3: The user selects the Logo picture file to generate the Logo; the user selects the Logo picture to be updated in the picture file list, and then selects OK.
[0067] S4: Extract the information of the selected Logo picture file and generate a Logo description file;
[0068] S5: Save the Logo description file to the BOOT partition. The application software will load the Boot par...
Example Embodiment
[0075] Example 2
[0076] Such as Figure 4 As shown, it is an embedded device startup Logo display method based on embodiment 1, including the following steps:
[0077] ST1: Boot Loader loads the Logo description file from the Boot partition; when the embedded device starts, it will run the Boot Loader first. The main functions of the Boot Loader include setting device kernel parameters, loading device tree files, loading kernel files, and finally starting the kernel. In this embodiment, the Boot Loader will additionally load the Logo description file from the Boot partition.
[0078] ST2: Boot Loader writes the Logo description file to the specified address in the memory; before Boot Loader starts the kernel, loads the Logo description file to the specified address in the memory. The memory area starting at this address and after it will not be initialized when the kernel is started, so the Logo description file in the memory is safe and will not be modified.
[0079] ST3: Boot Lo...
Example Embodiment
[0088] Example 3
[0089] Such as Figure 5 As shown, it is an embedded device startup Logo updating system in accordance with this embodiment, including:
[0090] The read-write module is used to provide the logo update interface; read the picture files in the USB storage device, load the picture file list and display it on the logo update interface; the user selects the Logo picture file to generate the Logo; the logo update interface can It is a child window of the main program of the embedded Linux device or an independent UI process. In this interface, the user can browse the picture files saved in the USB storage device and select the picture file.
[0091] The image conversion module is used to extract the information of the selected Logo image file and generate the Logo description file;
[0092] The save module is used to save the Logo description file to the BOOT partition. The application software will load the Boot partition. The partition format can be FAT32, EXT4 and ...
