Common means include outputting a print through a serial port, debugging online by JTAG or the like, reading a register inside a chip, tracking a software breakpoint or the like.
Generally, for a tested system with audio and video output, engineers need to additionally configure external devices such as a television, a display, a sound box and the like for system debugging; however, these common external devices (such as a television, a display, etc.) cannot directly cooperate with the debugging actions of engineers, and there is no way to set trigger conditions and grasp the corresponding sites according to the requirements of the engineers.
The existing means are mature and the engineers are skilled to use, but the following disadvantages exist:
1) With the debugging tool and the printing information, the system is not closest to the actual use scene, and the debugging means is a system variable which is introduced into the system, namely the system with debugging does not have problems, the actual system does not have problems, the system with debugging does not have problems, and the actual system does not have problems;
2) The printing and debugging tool can only grasp the site inside the system and can not save the site outside the system. Taking a multimedia player as an example, a printing tool and a debugging tool can not observe pictures when a problem occurs, and the existing television, display screen and the like can only observe the phenomenon after the problem occurs in the system, and can not know the situation (such as screen pattern and clamping) occurring before the problem occurs; and the time points of the external site cannot be matched with the time points of the internal site by the existing means;
3) When some external signals need to be converted, a conversion circuit or a conversion device is additionally added (for example, an engineering carried platform is HDMI output, but the external device needs to support LVDS, and then a hardware device or a hardware circuit for converting HDMI into LVDS is needed).
The typical test system needs to configure a television, a computer and a computer display and a power supply simultaneously to complete the whole test, but usually cannot record the picture of the tested system and cannot judge the abnormal time point of the picture.
