Description
Technical Field
The present invention relates to the field of integrated circuits, and in particular, to a method, an apparatus, a device, and a medium for updating a configuration of a power management circuit board.
Background
PMIC (Power management ic) on TCON-less board (LCD Timing control-less) of tv usually has two storage modes, i.e. with and without storage. An IC (Integrated Circuit) with memory only needs to be powered or input with correct timing control, and can output correct timing or voltage. Without a stored IC, in addition to power up and proper input control timing, an SOC (System on Chip) is required to download a code (set value in a register) to the IC through an I2C (Inter-Integrated Circuit, I2C bus for connecting a microcontroller and its peripherals) and the download code is required every power up.
When a TV complete machine is in production on trial, the code of the TCON-less board, namely the set value in the register of the IC on the TCON-less board, needs to be upgraded often because of some time sequence or display abnormity problems. For the IC without storage, only the value of the corresponding position in the main board program needs to be changed, the code of the TCON-less board and the main board software are upgraded together, and because the SOC on the main board writes the code into the IC of the TCON-less board through the I2C every time the power is on, new setting can be written into the IC. For code upgrading or updating of the TCON Power with storage, the whole machine is detached, then the TCON-less board is taken out, I2C of the TCON-less board is welded out, a tool of an IC supplier is connected to a computer, and upgrading is carried out through AP (a burner) or the tool of the IC supplier. Or the TCON-less board is taken down and then is taken to a production line to be upgraded through a crimping probe. And then, the upgraded TCON-less board is reassembled on the back board, and the back shell is punched to form the whole machine.
It can be seen from the above that, at present, for a TCON-less board with storage, upgrading of codes or software is troublesome, each board needs to be subjected to the steps of disassembling, welding, burning, assembling and the like, and if tens of boards or even hundreds of boards need to be upgraded, the workload is very huge. Moreover, the code is written into the TCON-less platelet with storage for a limited number of times, and part of the code can only be written for a few times, for example, the code can only be written into a Level shifter IC RT8949 (a type of integrated circuit board) for 3 times, and the code can be written into the IC for more than 3 times, so that the IC can be damaged. Therefore, the existing upgrading method for the stored TCON-less board is very complicated in process, equipment needs to be disassembled, and upgrading efficiency is seriously influenced.
The above is only for the purpose of assisting understanding of the technical aspects of the present invention, and does not represent an admission that the above is prior art.

and writing the second configuration data into the register on line through a bus, wherein the second configuration data is obtained from main program software data of the terminal equipment.
Furthermore, the main program software data of the terminal device includes the latest configuration data of the power management circuit board.
Referring to fig. 2, a first embodiment of a configuration updating method for a power management circuit board according to the present invention includes:
step S10, reading an address of a power management circuit board of the terminal equipment, and judging whether a register of the power management circuit board stores a configuration value or not according to the address;
specifically, in this embodiment, the terminal device is a television, the corresponding power management circuit board is a PMIC, and is usually soldered to a TCON-less board, the TCON-less board is connected to a main board through an FFC (Flexible Flat Cable), and the SOC is soldered to the main board. As shown in fig. 3, after the TV set is disassembled, it can be seen that the main board is connected to the TCON board through the FFC, and the TCON board is connected to the Panel (liquid crystal Panel) through the XB (connection terminal) and 12 COFs (Chip On Flex or Chip On film, which are commonly called as Chip On film). When the current register of the power management circuit board stores the configuration value (i.e. the PMIC is stored in a band), the PMIC is usually disassembled from the complete TV as shown in fig. 3, and then the code is written in the PMIC soldering external circuit, which is very tedious. In addition, the PMIC integrates a PMIC chip (PMIC chip is used to supply power to the Levelshifter IC, the Gamma IC, and the Driver IC (Driver IC)), a Gamma IC (for providing a Gamma voltage of the Driver IC on the Open cell liquid crystal panel), and a Levelshifter IC (for inputting a control signal to a circuit unit of a GOA (Gate on Array) for the panel), which are three-in-one PMIC, and in the following description, "power management circuit board" or "PMIC" refers to a three-in-one PMIC unless otherwise specified. When a system of the television is powered on, the SOC reads an address of the power management circuit board (each PMIC has an independent address), judges whether the power management circuit board has storage or not through the address, namely whether a register of the power management circuit board stores a configuration value (namely code) or not, and normally lights a panel of the television based on the configuration value in the process of starting the television.
Further, judging whether the address description of the address belongs to a preset storage address description; and when the address description belongs to the preset storage address description, judging that the register of the power management circuit board stores the configuration value.
Specifically, whether the register of the power management circuit board stores the configuration value is judged according to the address description of the acquired address, for example, the preset storage address description is 00ch68, whether the acquired address description is 00ch68 is judged, and if yes, the register of the power management circuit board stores the configuration value is judged. In fact, it can be determined according to the frequency of writing data into the address, and if data is written into the address every time the system is powered on, it is determined that the register of the power management circuit board does not store the configuration value.
In addition, it can be understood that the configuration updating method of the power management circuit board of the present invention is not limited to the three-in-one PMIC, and is also applicable to the case where the PMIC, the Gamma IC and the Level shifter IC are separated, and is also applicable to a TCON IC (timing control integrated circuit) and any panel with resolution and refresh rate.
Step S20, when judging that the register of the power management circuit board stores the configuration value, reading first configuration data stored in the register;
specifically, when it is determined that the register of the power management circuit board stores the configuration value (i.e., the PMIC stores the configuration value in a band), the first configuration data (i.e., the current code in the register, including a plurality of configuration values of the power management circuit board, such as a power supply voltage value of a certain module) is further read back from the register, and the read back first configuration data is used for subsequent determination.
Step S30 determines whether the first configuration data is the same as second configuration data to be updated to the register;
specifically, the first configuration data is compared with the second configuration data to be updated to the register, and whether the two types of data are the same is judged. Therefore, whether the configuration value of the power management circuit board needs to be updated or not is judged.
Optionally, after the step of determining whether the register of the power management circuit board stores the configuration value by the address, the method further includes: and when the register of the power management circuit board is judged not to store the configuration value, writing the second configuration data into the register to complete the configuration updating of the power management circuit board.
Specifically, when it is determined that the register of the power management circuit board does not store the configuration value (i.e., the PMIC is not stored), the second configuration data is directly written into the register to complete the configuration update of the power management circuit board.
And step S40, when the first configuration data is judged to be different from the second configuration data, writing the second configuration data into the register to complete the configuration updating of the power management circuit board.
Specifically, after the first configuration data and the second configuration data are determined to be different (that is, the configuration value of the power management circuit board needs to be updated), the second configuration data is written into the register, so as to complete configuration update of the power management circuit board. It should be appreciated that, unlike the PMIC that is stored without storage (configuration values are written to the registers each time the system is powered on), in the embodiment, only after determining that there is a need for updating and upgrading the configuration values of the power management circuit board, new configuration values are written to the registers, so that damage to the power management circuit board is greatly reduced.
Further, the second configuration data is written into the register online through a bus, wherein the second configuration data is obtained from main program software data of the terminal device.
Specifically, the PMIC is welded on a TCON-less board, an SOC is welded on a main board connected with the TCON-less board, the SOC comprises main program software data of the terminal equipment, and the second configuration data in the main program software data is written into a register of the power management circuit board on line through a bus (I2C bus). The main program software data of the terminal equipment comprises the latest configuration data of the power management circuit board, namely when a technician needs to update and upgrade the configuration value of the power management circuit board, even if the PMIC is stored in a storage mode with storage, the technician only needs to modify the corresponding configuration data of the main program software data, and then the configuration data of the power management circuit board is updated based on the modified main program software data, so that the steps of disassembling the terminal equipment, updating the configuration data of an external circuit and assembling the terminal equipment are omitted, and particularly, the updating efficiency is obviously improved when a large number of equipment conditions are met.
Optionally, after the step of determining whether the first configuration data is the same as the second configuration data to be updated to the register, the method includes: and when the first configuration data and the second configuration data are judged to be the same, judging that the power management circuit board does not need to be updated in configuration and finishing updating.
In this embodiment, after the terminal device is powered on, the SOC reads an address of the power management circuit board to determine a storage type of the PMIC of the terminal device, that is, whether the register stores the configuration data, and further determines whether the configuration data in the register is the same as the configuration data to be written if the PMIC is determined to be in a strip storage mode, that is, the register stores the configuration data, where the configuration data to be written is obtained from the main program data, and if the configuration data is the same, it is determined that the PMIC has a configuration data update requirement, and if the configuration data update requirement exists, the configuration data to be written is written to the register on a line to complete the update. Unnecessary configuration data updating is reduced, updating of PMIC configuration data based on main program data is achieved, steps of disassembling the terminal equipment, updating the configuration data of an external circuit and assembling the terminal equipment are omitted, and updating and upgrading efficiency is improved.
Referring to fig. 3, a configuration updating method for a power management circuit board according to a first embodiment of the present invention provides a second embodiment of the power management circuit board according to the present invention.
In this embodiment, the step S30 further includes:
step S301, adding all configuration values in the first configuration data to obtain a first configuration data sum;
step S302, adding all the configuration values in the second configuration data to obtain a second configuration data sum;
step S303, if the sum of the first configuration data is different from the sum of the second configuration data, it is determined that the first configuration data is different from the second configuration data.
Specifically, the first configuration data or the second configuration data have the same number of configuration values, such as a power supply voltage value of a certain module or a power supply current of a certain module. Adding all the configuration values in the first configuration data to obtain first configuration data sum; and adding all the configuration values in the second configuration data to obtain a second configuration data sum. It should be understood that if the second configuration data is modified or updated based on the first configuration data, the first configuration data sum obtained in the normal case is different from the second configuration data sum, so that by comparing the first configuration data sum with the second configuration data sum, it is determined whether the first configuration data sum is the same as the second configuration data sum.
It can be understood that, in this embodiment, whether the two types of configuration data are the same is determined by determining whether the sum of the respective configuration values in the two types of configuration data is the same, so that the determination speed is increased, and the update and upgrade efficiency is improved.
In addition, as shown in fig. 5, the present embodiment further provides a configuration updating apparatus for a power management circuit board, where the configuration updating apparatus for the power management circuit board includes:
a first judging module 10, configured to read an address of a power management circuit board of a terminal device, and judge, according to the address, whether a register of the power management circuit board stores a configuration value;
