Fig. 1 is a schematic diagram of a debug data acquisition scenario of a DP to HDMI chip in an example of the prior art. In fig. 1, the electronic device 200 outputs a DP signal to the USB Type-C interface 140 of the smart device 100 through the USB Type-C interface 210. The electronic device 200 may be a computer, a mobile phone, a tablet computer, a PDA (Personal Digital Assistant ), an electronic book reader, a multimedia player, or the like, which is provided with an USB Type-C interface. The smart device 100 is an integrated device that performs manipulation and man-machine interaction operation on a display panel through a touch technology, and in an embodiment, the smart device 100 may be an intelligent interaction tablet. In other application scenarios, other smart devices are also possible, such as computers, cell phones, tablet computers, PDAs (Personal Digital Assistant, personal digital assistants), e-book readers, multimedia players, etc.
Since the main control chip (SoC) 110 of the smart device 100 cannot directly read the DP signal, a DP-to-HDMI chip 120 is further disposed in the smart device 100, and the DP-to-HDMI chip 120 is configured to convert the DP signal into an HDMI signal and then send the HDMI signal to the main control chip 110, so that the main control chip 110 sends the HDMI signal to the display screen of the smart device 100 for display. The signal input end of the DP-HDMI chip 120 is connected to the USB Type-C interface 140, and the signal output end is connected to the main control chip 110.
The main control chip 110, as a main control chip in the smart device 100, typically integrates an analog and digital decoder, a demodulator, a central processing unit and an image processing unit, and may also have a rich peripheral interface. The main control chip 110 may be connected to different operating systems through a channel switch, and decode the audio/video signals transmitted by the different operating systems and transmit the decoded audio/video signals to a screen and a speaker for audio/video playing.
In some examples, for the firmware upgrade requirement of the DP-HDMI chip 120, the master control chip 110 is further connected to an IIC interface of the DP-HDMI chip 120, where IIC (Inter-Integrated Circuit) is IICBus, and the IIC interface is a serial communication bus interface, and the master control chip 110 is used as a master device, and upgrades the firmware of the DP-HDMI chip 120 as a slave device through the IIC interface.
In some examples, the smart device 100 further includes a power chip 130 for powering the external USB Type-C device interface through the USB Type-C interface 140.
When the intelligent device 100 is debugged, the serial port 150 of the intelligent device 100 needs to be connected to the debugging computer 300, and the serial port terminal program is run in the debugging computer 300, so that serial port information can be received or output. In the process of debugging the intelligent device 100, the debugging computer 300 records the running state of the main control chip 110 in a large amount.
As shown in fig. 2, after a fault problem is found in the debugging process, a new debug data acquisition link from DP to HDMI chip 120 is required, and the IIC interface of DP to HDMI chip 120 and the debug platelet 400 provided by the chip manufacturer are connected through a hardware welding wire, and a special computer 500 is further required to connect with the debug platelet 400. After the debug data acquisition link of the debug platelet 400 is built, the fault problems found in the debug process are reappeared, and when the fault problems are reappeared, the problems are analyzed by analyzing log information grabbed by the debug platelet 400, so that the problems are analyzed, and finally, the problems are solved. However, in this process of obtaining debug data, the connection line of the debug small board 400 and the IIC interface of the DP-to-HDMI chip 120 need to be soldered again, and the IIC interface is often already connected to the main control chip 110, so that this process of obtaining debug data is troublesome, and the obtaining cost is high, and the obtaining time is long.
In order to solve this technical problem, the embodiment of the present application provides a method for obtaining debug data of a DP-to-HDMI chip, which is applied to the above-mentioned smart device 100, where the smart device 100 includes a main control chip and a DP-to-HDMI chip, and the main control chip is connected to an IIC interface of the DP-to-HDMI chip, as shown in fig. 3, in an exemplary embodiment, the method includes the following steps:
s301: receiving a debug data reading instruction, wherein the debug data reading instruction is used for reading the debug data of the DP-HDMI chip;
the debug data reading instruction is used for driving the main control chip to read debug data from the HDMI chip, and the debug data reading instruction may be set to be automatically triggered when the intelligent device detects a debug fault, or may be triggered by an external device, for example, the main control chip receives a debug data reading instruction sent by an external storage device through a serial port of the intelligent device, in fig. 1, may receive a debug data obtaining instruction sent by the debug computer 300, and this implementation may input a command, for example, a saveddlog command, on a serial port terminal program of the debug computer 300, where the command is input to the main control chip through a serial port, so that the main control chip establishes communication with the DP to HDMI chip. In other examples, such a debug data read command may also be triggered by a user setting the smart device, such as adding an option to a menu button of the smart device 100, triggering the option to send a debug data read command to the smart device, and so on.
The debugging data are data generated by the DP-HDMI chip in operation, and when a fault is found in the debugging process of the intelligent device, the fault may be caused by abnormal operation of the DP-HDMI chip or abnormal audio/video signals processed by the DP-HDMI chip. Therefore, in this embodiment of the present application, the debug data may include multiple data object types, for example, may be running state data of the DP-to-HDMI chip, or may also be display parameters of an audio/video signal processed by the DP-to-HDMI chip, display performance data of the smart device, and so on.
S302: and responding to the debugging data reading instruction, and sending a debugging data acquisition request to the DP-HDMI chip through the main control chip.
S303: and receiving the debugging data sent by the DP-HDMI chip through the main control chip.
The main control chip is connected with an IIC bus communication interface of the DP-HDMI chip, the DP-HDMI chip is a main device of the IIC bus communication protocol, the DP-HDMI chip is used as a slave device of the IIC bus communication protocol, each device on the IIC bus corresponds to a unique address, and data transmission between the main device and the slave device is established on the basis of the address. The transmission of data on the IIC bus must be started with a start signal and stopped with an end signal. The start and end signals are generated by the master device.
In the existing connection, when firmware upgrade is performed on the DP-to-HDMI chip through the IIC bus, the main control chip may write data into the DP-to-HDMI chip. In the method of the embodiment of the present application, the main control chip reads data from the DP to HDMI chip.
In response to the debug data reading instruction, the main control chip first establishes communication connection with the DP-to-HDMI chip, and in one example, the debug data reading instruction further includes an IIC communication address of the DP-to-HDMI chip, so as to direct the main control chip to establish IIC bus communication connection with the DP-to-HDMI chip, and send a debug data acquisition request to the DP-to-HDMI chip through the main control chip in an IIC bus communication protocol.
In a specific implementation, the main control chip sends a START signal, and then the DP-HDMI chip STARTs to monitor the IIC bus in preparation for receiving data. And then, the main control chip sends a data frame of 7-bit equipment address plus one-bit read-write operation, after the DP-HDMI chip receives the data frame, the DP-HDMI chip compares whether the address is a target equipment or not, and if so, a response signal is sent to the main control chip, so that the IIC bus communication connection with the main control chip is established. After the IIC bus communication connection is established, the main control chip sends a debugging data acquisition request to an IIC interface of the DP-HDMI chip, and the DP-HDMI chip sends debugging data corresponding to the request to the main control core making according to the request until the main control chip generates a STOP signal, so that the IIC bus is released to finish communication.
In the embodiment of the application, the main control chip of the intelligent device is connected with the IIC bus of the DP-to-HDMI chip, after receiving the debug data reading instruction, the main control chip sends a debug data acquisition request to the DP-to-HDMI chip, and receives the debug data sent by the DP-to-HDMI chip through the main control chip, so that when the DP-to-HDMI chip is debugged, the debug data is acquired from the DP-to-HDMI chip without additionally using a debug platelet provided by a chip manufacturer, the IIC bus connection between the original main control chip and the HDMI chip is not required to be removed, and the debug platelet and the DP-to-HDMI chip are not required to be welded, so that the debug data acquisition process of the DP-to-HDMI chip is more convenient, the debug cost is saved, and the debug time is shortened.
In one embodiment, the main control chip may send the debug data to the external storage device through the serial port after receiving the debug data, for example, in the scenario of fig. 1, the main control chip directly sends the debug data to the debug computer 300 through the serial port connection after receiving the debug data, so that when a developer is in debugging, only needs to send a debug data reading instruction to the intelligent device, and the debug data of the DP-to-HDMI chip can be directly obtained from the debug computer.
In other examples, the intelligent device may send the debug data to an external storage device through a USB interface, that is, a developer may connect the intelligent device through the USB storage device, so as to obtain the debug data.
In one embodiment, after the intelligent device receives the debug data sent by the DP-to-HDMI chip through the master control chip, the intelligent device further stores the debug data in a register of the master control chip.
Since the debug data may include multiple data object types, in a preferred embodiment, as shown in fig. 4, before the debug data is sent to the external storage device through the USB interface or the serial port of the smart device, the method further includes:
s401: identifying an object type of the debug data;
s402: and according to the object type of the debugging data, storing the debugging data in a register of the main control chip in a classified manner.
The main control chip may identify the object type of the debug data by identifying the data type, the data format, etc. of the debug data, and in one example, the main control chip may also obtain the object type of the debug data obtained by the request according to the data type corresponding to the debug data obtaining request.
The main control chip can store the debug data in different files in a register of the main control chip according to the object type of the debug data, so that a developer can accurately acquire the wanted debug data.
In one embodiment, the object type of the debug data includes at least one of:
and the DP converts the operation log data of the HDMI chip, the display parameters of the input signals and the display parameters of the output signals of the DP converts the operation log data of the HDMI chip, and the display performance data of the intelligent device.
The running log data is log, the log refers to the record of events or operations occurring in the DP-HDMI chip, and the log can be queried and retrieved. The DP to HDMI chip may generate a log (including an error log and an operation log) record during operation, where the log records information about hardware, software and system problems, and in some examples, the log records descriptions of related operations such as date, time and actions. When debugging fails, engineers can check the reasons of the failure and effectively solve the problems by grabbing the log of the DP-HDMI chip and checking and analyzing the log.
When the reason of the fault is checked, the display parameters of the input signal and the output signal of the DP-to-HDMI chip can be checked, so in another embodiment, the debug data further includes the display parameters of the input signal and the display parameters of the output signal of the DP-to-HDMI chip.
The display parameters indicate how planar video data is to be displayed in the display device, e.g., the display parameters may include resolution, color space, gamma values, etc.
If the display parameters of the input PD signal are abnormal, it indicates that the reason for the occurrence of the fault is the signal source, and if the display parameters of the output HDMI signal are abnormal, it indicates that the switching process of the DP to HDMI chip is faulty.
In practical applications, the DP-to-HDMI chip typically stores display parameters in internal registers, for example, some registers may indicate the resolution of the input signal, the video color space of the input signal, some registers indicate the resolution of the output signal, and the video color space of the output signal, so in one example, when obtaining the display parameters of the input signal and the output signal of the DP-to-HDMI chip, the debug data obtaining instruction further includes a register address in the DP-to-HDMI chip, so that the display parameters can be obtained by directly obtaining the data in the register address.
In other examples, the main control chip may also obtain the display parameter from the DP to HDMI chip in other existing manners.
In the beginning of the electronic device 200 and the smart device 100 establishing a DP communication connection, the electronic device 200 first obtains display performance data of the smart device 100 through the DP-to-HDMI chip 120, where the display performance data includes extended display identification data (Extended Display Identification Data, EDID) and display port configuration data (DisplayPort Configuration Data, DPCD).
The extended display identification data is a VESA standard data format for indicating HDMI display performance of the smart device, and includes parameters related to the monitor and its performance, including vendor information, maximum image size, color setting, vendor preset, limitation of frequency range, and character strings of display name and serial number, etc.
