[ EXAMPLES one ]
In the existing display control device, whether hardware on a non-plug-in card controller is replaced or a daughter card on the plug-in card controller is plugged in and out, firmware programs such as an FPGA and an MCU on a display control device motherboard need to be updated, however, in the existing program updating method, a debugger generally downloads an updating program manually through an upper computer, and particularly, for the plug-in card control device, the updating program needs to be downloaded manually every time the daughter card is replaced, the updating process is complex, and the debugging difficulty is high, so as to solve the above-mentioned defects in the prior art, as shown in fig. 1, an embodiment of the present invention provides a firmware program updating method, which is used for simplifying the firmware program updating process of the display control device, so that the debugging is more convenient, and the automation degree is higher.
Specifically, referring to fig. 1, a firmware program upgrading method according to an embodiment of the present invention includes:
step S1: acquiring version information of the display control equipment;
step S2: searching a target firmware program from a plurality of firmware programs prestored in the display control equipment according to the version information and the mapping relation between the version information and the firmware programs; and
step S3: and acquiring and loading the target firmware program for upgrading.
The firmware program upgrading method is applied to a main control card of a display control device (which may be a card-inserted device or a non-card-inserted device), where the main control card is, for example, a main control card based on an arm (advanced RISC machines), where the version information in step S1 includes, for example, version information of main board hardware, and the display control device is further provided with, for example, a main board, the main board is connected to the main control card, and the main board is provided with a plurality of electrical elements, such as an FPGA (Programmable logic device) for video data processing and an MCU (micro control Unit) for processing control instructions, and other hardware, such as a Real Time Clock (RTC) chip and a FLASH Memory (FLASH Memory). When hardware such as RTC and FLASH is replaced or upgraded, the display control device will have different motherboard hardware version information, and at this time, firmware programs such as FPGA or MCU on the motherboard need to be upgraded to match the upgraded motherboard. Therefore, each version information has a firmware program uniquely corresponding to it, i.e., the mapping relationship between the version information and the firmware program mentioned in step S2. The plurality of firmware programs pre-stored in the display control device in step S2 are, for example, stored in a memory on the main control card, where the plurality of firmware programs refer to firmware programs corresponding to all version information when conditions allow, and may be selected according to the type of an actual application scenario and conditions such as memory resource occupation during actual application, so that different firmware programs are pre-stored as much as possible, and the more the pre-stored firmware programs are, the more convenient the upgrade operation is. The mapping relationship between the version information and the firmware program is used to represent the relationship between the version information of the display control device and the firmware program thereof, and may be in a table form or a document form. For example, the mapping relationship between the version information and the firmware program is that the version information a01 corresponds to the firmware program a01, the version information a02 corresponds to the firmware program a02, and the plurality of firmware programs pre-stored on the display control device include the firmware programs a01 and a02, for example, if the version information acquired in step S1 is a01, in step S2, the target firmware program a01 is searched from the firmware programs a01 and a02 according to a01 and the mapping relationship, and in step S3, the firmware program a01 is acquired and loaded for the FPGA or MCU on the motherboard to be upgraded. Of course, the above is merely an example, and is not intended as a limitation to understanding the present embodiment.
It should be noted that, in this embodiment, it is not limited that the plurality of firmware programs pre-stored in the display control device are fixed and unchangeable, and the number of the firmware programs pre-stored in the display control device is limited in practical application, so as to continuously update the display control device, the version information is more and more, and the plurality of firmware programs pre-stored in the display control device may not meet the matching of more version information, so that the plurality of firmware programs pre-stored in the display control device may still be supplemented or replaced by, for example, sending the firmware programs through an upper computer or obtaining the firmware programs through a cloud server, so as to meet more requirements, and meanwhile, the mapping relationship between the corresponding version information and the firmware programs needs to be supplemented or replaced. After a plurality of pre-stored firmware programs and the mapping relation between the version information and the firmware programs are supplemented or replaced, the display control equipment can still be automatically upgraded by the firmware program upgrading method. The embodiment emphasizes that after the firmware programs as many as possible are prestored in the display control device, the firmware program updating device does not need to be manually downloaded each time, so that the manual operation of the display control device during updating is reduced as much as possible, and the program upgrading process is simplified.
Further, in an embodiment, the version information includes, for example, the aforementioned motherboard hardware version information, and the step S1 specifically includes, for example:
step S111: sampling the resistance value of the mainboard;
step S112: and determining the hardware version information of the mainboard as the version information according to the resistance value and the mapping relation between the resistance and the hardware version of the mainboard.
Since the resistance value of the motherboard changes when the hardware on the motherboard changes, each piece of motherboard hardware version information has a resistance value uniquely corresponding to the hardware version information, and the unique correspondence is set as the mapping relationship between the resistance and the hardware version in step S112, which may be in a table form or a document form, and is pre-stored in the memory of the display control device, so that the motherboard hardware version information is determined as the version information according to the resistance value of the motherboard and the mapping relationship between the resistance and the hardware version when step S112 is executed. Of course, the resistance value of the main board may be a certain value or a range of values, and the embodiment is not limited. In step S111, the resistance of the motherboard may be sampled by an ADC (Analog-to-digital converter) for example.
Further, in one embodiment, step S2 further includes, for example:
step S211: and the firmware upgrading device is used for searching a target hardware upgrading program from the plurality of firmware programs prestored in the display control equipment according to the mainboard hardware version information and the mapping relation between the version information and the firmware programs to serve as the target firmware program.
It should be noted that the target hardware upgrade program in step S211 refers to a firmware program corresponding to the motherboard hardware version information and used for upgrading, for example, an FPGA or an MCU on the motherboard, so that the FPGA or the MCU on the motherboard can adapt to a corresponding hardware version.
Furthermore, in the card-inserted display control device, different daughter cards are often required to be replaced according to usage requirements, and the firmware programs of the FPGA and the MCU on the main card also need to be upgraded to match the replaced daughter card, where the daughter card may be, for example, an input card, an output card, a transmitter card or a cascade card used on the display control device, and the daughter card includes, for example, a processing chip and a microcontroller. As such, in one implementation, the version information mentioned in the foregoing step S1 further includes, for example, daughter card identification information, where the identification information of the daughter cards refers to, for example, a unique corresponding model id code of each daughter card (or each identical daughter card), for example, contains type information of the daughter cards, and the type information indicates, for example, whether it is an input card, an output card, a sending card, a cascading card, or the like. The identification information of the sub-card may also include, for example, interface type information of the sub-card, for example, whether the interface type information of the sub-card indicates that the interface is a dp (display port) interface, an SDI (digital component serial interface), an HDMI interface, or the like, or may also include, for example, hardware information of the sub-card, for example, whether the hardware information indicates a hardware version of a processing chip and a microcontroller on the sub-card, or the like. The identification information of the daughter cards is not limited to the modem id code of a single daughter card, for example, the identification information of the daughter card may be the modem id code of one daughter card when the display control device only replaces one of the daughter cards, and for example, the identification information of the daughter card may be a set of the modem id codes of a plurality of daughter cards when the display control device replaces a plurality of daughter cards simultaneously.
Further, in one embodiment, step S2 further includes, for example:
step S212: and searching a target sub-card upgrading program from the plurality of firmware programs prestored in the display control equipment according to the sub-card identification information and the mapping relation between the version information and the firmware programs to serve as the target firmware program.
It should be noted that the target daughter card upgrading program described in step S212 refers to an upgrading firmware program corresponding to the daughter card identification information and used for the motherboard, such as an FPGA or an MCU, so that the FPGA or the MCU on the motherboard can be adapted to the corresponding daughter card.
It should be noted that in the first embodiment of the present invention, the version information may only be one of the motherboard hardware version information and the daughter card identification information, or both of them. Correspondingly, step S2 may include only one of step S211 and step S212, or both. Correspondingly, the target firmware program may be one of the target hardware upgrade program and the daughter card upgrade program, or a combination thereof. And the target firmware program can be an upgrading program for an FPGA on the mainboard or an upgrading program for an MCU on the mainboard. The corresponding pre-stored firmware programs comprise firmware programs of the FPGA corresponding to different versions of information and firmware programs of the MCU corresponding to different versions of information.
Further, in an embodiment, the version information in step S1 further includes, for example, current version information and previous version information, and step S1 obtains the current version information, specifically, obtains current daughter card identification information by directly reading a ModeID code of the current daughter card, or obtains current motherboard hardware version information according to step S112. The former version information is, for example, manually preset, such as original motherboard hardware version information of the display control device, and is preset in the memory at the time of factory shipment, or is further, for example, automatically stored, and, for example, step S0 is further performed before step S1 is performed each time: detecting a variation of the display control apparatus and outputting a variation signal; wherein the change of the display control device refers to the occurrence of power-off restart of the display control device or hot plug action of the daughter card. The step S1 executed after the step S0 includes, for example: in response to the output of the variation signal in step S0, the acquired current version information is stored as the previous version information when step S1 is executed again (when step S0 outputs the variation signal again). For example, the version information is motherboard hardware version information mentioned in the foregoing embodiment, the resistance value of the initial motherboard of the display control device is R0, step S0 detects that the display control device is restarted after first power failure, and outputs a change signal, step S1 samples that the resistance value of the motherboard is R1 after power failure and restart in response to the change signal, the motherboard hardware version information corresponding to the resistance value R1 is current version information, the motherboard hardware version information corresponding to the resistance value R0 is previous version information, step S1 stores the motherboard hardware version information corresponding to the resistance value R1 in the memory, when the display control device is restarted after second power failure, step S0 outputs the change signal again, at this time, step S1 samples that the resistance value of the motherboard is R2 after second power failure and restart in response to the change signal, at this time, the motherboard hardware version information corresponding to the resistance value R2 is current version information, and the motherboard hardware version information corresponding to the motherboard resistance value R1 after first power failure is read that is previous version information of the motherboard hardware corresponding to the motherboard hardware version information after power failure and restart for the previous version information And (4) version information. When the version information is the identification information of the daughter card mentioned above, the execution principle of step S1, such as step S0, is similar to the above description, and will not be illustrated here.
In this embodiment, step S2 specifically includes, for example:
step S21: comparing the current version information with the previous version information;
step S22: and searching the target firmware program from the plurality of firmware programs according to the mapping relationship between the current version information and the firmware programs when the current version information is inconsistent with the previous version information.
As shown in the above example, after the first power-off restart, step S21 compares the motherboard hardware version information (current version information) corresponding to R1 with the motherboard hardware version information (previous version information) corresponding to R0, and step S22 searches the target firmware program in response to the inconsistency between the two, and if the two are the same, the target firmware program does not need to be searched. Or, for example, if the step S10 detects that the daughter card is plugged, a different daughter card may be replaced, where the current daughter card is the daughter card B, and the current version information obtained in step S1 is the modem id code of the daughter card B, and the modem id code of the daughter card B is prestored as the previous version information of the next plugging. When the plugging is detected next time, for example, the daughter card B is replaced by the daughter card C, step S1 obtains that the current version information is the ModeID code of the daughter card C, and the previous version information is the ModeID code of the daughter card B. The current version information (ModeID code of the daughter card C) and the previous version information (ModeID code of the daughter card B) are compared in step S21, and the target firmware program suitable for the daughter card C is searched in step S22 according to the inconsistency between the current version information and the previous version information. If the step S0 detects that the plugging action occurs, but the daughter card is not actually replaced, but still is the daughter card B, the step S22 does not need to search the target firmware program according to the correspondence between the previous version information and the current version information.
The embodiment is suitable for upgrading the MCU firmware program on the mainboard, and because the MCU program cannot be lost due to power failure, the matching process and the loading process of the target firmware can be skipped when the current version information and the previous version information are compared and the current version information and the previous version information are the same, so that the resource saving and unnecessary occupation of the updating time are facilitated. For upgrading the firmware program of the FPGA, the program is lost due to power failure, so that the target firmware program can be directly searched without going through step S21.
