Description
Technical Field
The invention relates to a method for quickly verifying a screen and a machine display interface.
Background
Based on the current market environment, many electronic devices have complex display screen verification modes, many processes, complex verification processes and poor universality, different screens are often verified and supported by different hardware devices, and the device cost and the time cost are high, so that a more simple and convenient method is needed to solve the display screen verification problem.
Disclosure of Invention
In order to overcome the problems in the prior art, the invention relates to a method for quickly verifying a screen and a machine display interface, which comprises the following specific technical contents:
a method of quickly verifying screen and machine display interfaces, comprising:
a unified mirror image synthesis step, wherein the normal display of a machine is debugged in the step, and then display parameters are acquired to generate a unified mirror image, wherein the unified mirror image comprises a file list to be packed, a loader file for starting a system, a partition information file and a resource image;
an SD card firmware creating step, wherein an SD starting mark is written in the SD card in advance, and the unified mirror image is burnt into the SD card;
starting a verification step, wherein whether an SD card is inserted or not is detected after the machine is powered on;
when detecting that an SD card is inserted, firstly searching whether an SD starting mark exists; when the SD card insertion is not detected or the SD starting mark is not detected, directly running the emmc program of the machine, and normally starting the machine;
when the SD boot flag is retrieved, the unified image is read to boot the machine.
In one or more embodiments of the present invention, the resource image includes device tree information of a boot image and a kernel.
In one or more embodiments of the invention, the unified mirror may be customized according to display interface types, wherein adaptable interface types include LVDS, MIPI and EDP.
The invention has the beneficial effects that:
1) The manufacturing environment is simple; the SD card starting firmware can be manufactured by only one normally displayed computer, and only the SD card is needed to start the equipment in batch test, so that the burning of a plurality of computers to a machine is reduced;
2) Small mirror image and fast burning; the SD card starting firmware is about 3M generally, only 1 second is needed for burning the SD card, and compared with the traditional hundred-million-sized android mirror image, the needed storage space and burning time are much shorter;
3) The mirror image in the equipment is not influenced; the verification process can be started only by inserting the SD card, the SD card is dialed to restart the equipment after the insertion verification is finished, the equipment can run the emmc program again, and the original mirror image cannot be influenced;
4) Compatibility and customization are more flexible; the display interfaces of types such as LVDS, MIPI, EDP and the like can be correspondingly supported by manufacturing the mirror images with different resolutions or different interfaces in the SD card, so that repeated burning before the SD card is dragged to a computer with equipment is avoided, and the SD card is favorable for production and flow simplification.

Detailed Description
The scheme of the present application is further described below with reference to figures 1 and 2:
a method of quickly verifying screen and machine display interfaces, comprising:
a unified mirror image synthesis step, wherein the normal display of a machine is debugged in the step, and then display parameters are acquired to generate a unified mirror image, wherein the unified mirror image comprises a file list to be packed, a loader file and a partition information file which are started by a system, and a resource image containing equipment tree information of a starting-up picture and a kernel;
an SD card firmware creating step, wherein an SD starting mark is written in the SD card in advance, and the unified mirror image is burned into the SD card;
starting a verification step, wherein whether an SD card is inserted or not is detected after the machine is powered on;
when detecting that the SD card is inserted, firstly searching whether an SD starting mark exists; when the SD card insertion is not detected or the SD starting mark is not detected, directly running the emmc program of the machine, and normally starting the machine;
when the SD boot flag is retrieved, the unified image is read to boot the machine.
The unified image may be customized according to display interface types, where adaptable interface types include LVDS, MIPI and EDP.
We can make SD card based on RK3288 platform of Rockchip series, firstly we need to make SD card start firmware, and the first step is to debug the device to normal display, we use a 10.1 inch 800 × 1280lvds display screen, and the display parameter information of the screen is as follows:
and configuring a corresponding software LVDS screen as follows, and then compiling to generate a corresponding mirror image.
When the driver is debugged to enable the machine to display normally, the SD card boot firmware can be manufactured, wherein the firmware mainly comprises the following components: the file list package-file, the loader file miniloaderl.bin for system startup, the partition information file parameter.txt, and the resource image resource.img containing the device tree information of the startup picture and the kernel are required to be packed.
SD card boot firmware can be synthesized by using Linux tools, afptool and rkImageMaker, which are provided by Rockchip, and the following commands are required to be executed to finally generate a uniform image update.
./afptool-pack./Image/update.img
./rkImageMaker-RK32 MiniLoaderAll.bin Image/update.img
update.img-os_tpye:androidos
Then using a Rayleigh core micro-creation long beak disk tool V1.46, inserting the SD card into a computer, identifying and selecting the SD starting and clicking a firmware selection button by the tool, and selecting the corresponding firmware for creation.
The above-described preferred embodiments should be considered as examples of the embodiments of the present application, and any technical deductions, substitutions, improvements and the like, which are similar, approximate or based on the present application, should be considered as the protection scope of the present patent.
