Embodiment

[0029] This example takes an IPTV set-top box using an embedded linux operating system as an example, where the constant C is 100 as an example, and the system flow chart is as follows figure 1 , the progress display function workflow is as follows figure 2 .

[0030] The overall working process of the IPTV set-top box is: first, the system is powered on, the bootloader starts, the hardware device is initialized, the function call picture is displayed, the boot screen is displayed, the kernel code of the linux operating system is copied to the system RAM (Random Access Memory, random access memory) memory, and linux is started After the kernel, the kernel multitasking environment is established, create a new thread, execute the boot progress display function, load the root file system, the progress display ends at the same time, the progress display is 100%, execute the application program, and enter the standby screen.

[0031] Wherein, boot loader (Bootloader) startup is d...

Abstract

The invention relates to the technique for displaying a startup picture of an embedded device and solves the problems that in the process of starting up the embedded device, latency time is long and nod feedback is displayed on the screen and provides a method for displaying starting up progress of the embedded device. The technical proposal is: the method is characterized by comprising the following steps: a. electrifying the system, starting up a boot loader program, invocating a display function to display the startup picture; b. starting up operating system nucleus, establishing a kernel thread and invocating a progress display function; c. operating the progress display function, displaying corresponding progress bars and percentage number according to available machine time; d. completing system startup and withdrawing the progress display function; the invention has the beneficial effects of offering convenience to the users and being applicable to embedded devices.

Description

technical field [0001] The invention relates to an embedded device, in particular to a boot screen display technology. Background technique [0002] In the 1990s, embedded technology was in full swing, and it has become the common development direction of communication and consumer products. With the development of informatization, intelligence, and networking, embedded system technology will also achieve broader development. space. Real-time multitasking operating system (RTOS) has become the mainstream of embedded systems, which determines that the boot time of embedded devices is usually more than ten seconds or twenty seconds. A still boot screen is usually mistaken by users as Equipment failure, very inconvenient. In the working process of embedded devices, firstly, the boot loader initializes the hardware devices, establishes the mapping map of the memory space, brings the software and hardware of the system to a suitable state, and prepares the correct environment f...
