The screen projection chip device can be debugged by the burning, debugging unit and its HDMI interface, and the product firmware can also be updated; and there are six modes for debugging and burning the screen projection chip device (as shown in the following examples 1-6), so that it can adapt to more usage environments and debugging equipment. Example 1

[0021] like Figure 2 As shown, the projection chip device 826x (RX) is abnormal and basic information is printed for simple debugging.

[0022] After the burning and debugging unit board (8270UVC) reads the EDID (DebugRX.bin) file in the U-Disk, the projection chip device is powered on and inserted into the interface HDMI RX on the burning and debugging unit board (8270UVC). At this time, the projection chip device will read the EDID (DebugRX.bin) file as DebugRX information. In addition, the projection chip device will transmit the serial port printing information back to the burning and debugging unit board (8270UVC) through the HDMI I2C interface via the HDMI-RX interface, and then the burning and debugging unit board (8270UVC) will transmit it to the interface HDMI-TX to print it out on the display, and at the same time transmit it to the U-Disk for archiving.

The LED flashes quickly when the file is transferred, and the LED is always on when the transfer is completed. Example 5

[0026] like Figure 6As shown, update the firmware of the 836x (TX) projection chip device. After the burning and debugging unit board (8270UVC) reads the EDID (FWupdate.bin) of the U-Disk, the AM826x.bin of the U-Disk is temporarily stored in the DDR-Buffer of the burning and debugging unit board (8270UVC). After the projection chip device is powered on, insert it into the HDMITX port of the burning and debugging unit board (8270UVC), and automatically update the firmware of the projection chip device through the HDMI CEC command. When the firmware is updated, the LED flashes quickly, and the LED is always on after the transmission is completed. Example 6

[0027] like Figure 7 As shown, update the firmware of the 836x (TX) projection chip device. After the burning and debugging unit board (8270UVC) reads the EDID (FWupdate.bin) of the computer PC / NB-MPTOOL, the AM826x.bin of the computer PC / NB-MPTOOL is temporarily stored in the burning and debugging unit board (8270UVC) storage DDR-Buffer. After the projection chip device is powered on, it is inserted into the HDMI TX port of the burning and debugging unit board (8270UVC). The firmware of the projection chip device is automatically updated through the HDMI CEC command. When the firmware is updated, the LED flashes quickly, and the LED is always on after the transmission is completed. Example 7

[0028] like Figure 1 As shown, the abnormal alarm unit is used to receive feedback from the data analysis module and send a red flashing instruction to the LED indicator when it is determined that the data packet used for debugging is abnormal. When the data analysis module determines that the data packet used for debugging is abnormal, its burning and debugging unit can display the abnormal information to the display through the interface HDMI-TX.

[0029] The data analysis unit can determine whether the debugging data packet has an abnormality based on the data consistency coefficient of the debugging data packet, the probability coefficient of the integrity of the data packet file, and the number of read and write cycles of the data packet file, including: ; In the formula, Indicates the probability coefficient of abnormality in the data packet used for debugging. Indicates the data consistency coefficient of the data packet used for debugging. The probability coefficient indicating the integrity of the data packet file, Indicates the number of read and write cycles of the data packet file.

[0030] The data analysis unit determines the data consistency coefficient of the data packet according to the proportion of data packets lost during storage or transmission, the proportion of redundant data used to compensate for lost data packets, and the delay time of data packets transmitted to the storage DDR-Buffer. The coefficients are: ; In the formula, Indicates the data consistency coefficient of the data packet used for debugging. Indicates the proportion of data packets lost during storage or transmission. Indicates the proportion of redundant data used to compensate for lost data packets, Indicates the delay time of data packet transmission to storage DDR-Buffer.

[0031] The data analysis unit determines the probability coefficient of the integrity of the data packet file according to the change ratio of the data packet size during the burning or debugging process, the proportion of repeated transmission of data in the data packet during the burning or debugging process, and the proportion of data packet loss during storage or transmission. The probability coefficients are: ; In the formula, The probability coefficient indicating the integrity of the data packet file, Indicates the change ratio of the data packet size during the burning or debugging process. Indicates the percentage of data in a data packet that is repeatedly transmitted during programming or debugging. Indicates the proportion of data packets lost during storage or transmission.

[0032] Among them, the proportion of FWupdate.bin data packets lost during the burning process of the projection chip device 826x (RX) is (Loss ratio = lost data size ÷ total FWupdate.bin data packet size).

[0033] The proportion of redundant data used to compensate for the lost FWupdate.bin data packet is (Redundant data ratio = data size used to compensate for lost data ÷ total size of FWupdate.bin data packet).

[0034] The delay time of FWupdate.bin data packet transmission to storage DDR-Buffer is (ns). Then we have: ; From the above calculation, we can know that the data consistency coefficient of the FWupdate.bin data packet during the programming process to the projection chip device 826x (RX) is , and compare multiple groups of data, there are: Table 1 Relationship between some embodiment data and monitoring parameters and data packet data consistency

[0035] Among them, the FWupdate.bin data packet changes in the proportion of the size of the FWupdate.bin data packet during the burning process to the projection chip device 826x (RX). (Change ratio = size of the changed and compressed string in the FWupdate.bin data packet ÷ total size of the FWupdate.bin data packet).

[0036] The percentage of data in the FWupdate.bin data packet that is repeatedly transmitted during the burning process is (Percentage of repeated transmission = size of data that is repeatedly transmitted, burned, and compressed ÷ total size of FWupdate.bin data packet).

[0037] The proportion of FWupdate.bin data packets lost during the burning process is (Loss ratio = lost data size ÷ total FWupdate.bin data packet size). Then we have: ; From the above calculation, we can know that the probability coefficient of the integrity of the data packet file of the FWupdate.bin data packet during the burning process to the projection chip device 826x (RX) is , and compare multiple groups of data, there are: Table 2 Relationship between some example data and monitoring parameters and file integrity

[0038] Then, the FWupdate.bin data package is being burned to the projection chip device 826x (RX). The number of read and write cycles of the FWupdate.bin data package file in the U-Disk is The probability coefficient of the integrity of the FWupdate.bin data package file is The data consistency coefficient of the FWupdate.bin data packet is , then we have: ; From the above calculation, we can know that during the process of programming the FWupdate.bin data packet to the projection chip device 826x (RX), the probability coefficient of the FWupdate.bin data packet being abnormal is , then comparing multiple groups of data, we have: Table 3 Data and burning status of some embodiments

[0039] From the above data, we can know that when the sample data tends to be infinite, there will be anomalies based on the probability The dividing line is used to evaluate whether the FWupdate.bin data packet is abnormal when burning to the projection chip device 826x (RX). When , it means that the data packet used for debugging is obviously abnormal; when , it indicates that the status of the data packet used for debugging is normal.

[0040] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
