Detailed Description
The embodiment of the invention provides a chip firmware upgrading method and device, electronic equipment and a storage medium, which are used for solving the technical problems of high labor cost and poor customer experience of the conventional chip upgrading mode.
In order to make the objects, features and advantages of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the embodiments described below are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a flowchart illustrating steps of a method for upgrading a chip firmware according to an embodiment of the present invention.
The invention provides a chip firmware upgrading method, which is applied to a first chip; the first chip carries first firmware information, and the first firmware information comprises a first firmware version number; the method comprises the following steps:
in an embodiment of the present invention, the apparatus may be an image forming apparatus such as a printer, a copier, or the like. The first chip and the second chip may be consumable chips mountable on the device to establish a connection with the device. The consumable chip records relevant information of equipment such as equipment model and equipment version number.
In the embodiment of the present invention, when the first chip is mounted on the device and establishes a communication connection with the device, the second firmware version number of the second chip mounted on the device may be acquired. The first chip may be a chip that has already completed firmware upgrade, and the second chip may be one or more chips.
After the first chip obtains the second firmware version number of the second chip, the first firmware version number and the second firmware version number can be compared, and when the first firmware version number is judged to be larger than the second firmware version number, the firmware version representing the first chip is higher than the firmware version of the second chip; at this time, the first chip may send its first firmware version number to the second chip to update the firmware information of the second chip to the first firmware information of the first chip.
Taking the printer as an example, when the first chip is installed in the printer, the first chip may query the second firmware version number of the second chip installed in the printer through a preset protocol (e.g., IIC, spi, IOS14443B, wifi, bluetooth, etc.). When the version number of the second firmware is lower than the version number of the first firmware of the first chip, the first chip sends a programming instruction to the second chip through a preset protocol, and updates the first firmware information carried by the first chip to the second chip.
In the embodiment of the present invention, when the first firmware version number of the first chip installed on the device is greater than the second version number of the second chip installed on the device, the first chip may send corresponding first firmware information to the second chip for firmware upgrade. Therefore, chips needing firmware upgrading do not need to be replaced or returned to the factory for upgrading again. The labor cost is reduced, and the customer experience is improved.
Referring to fig. 2, fig. 2 is a flowchart illustrating a method for upgrading a chip firmware according to another embodiment of the present invention. The method specifically comprises the following steps:
in the embodiment of the present invention, the first chip has a first communication part and a second communication part, and step 201 may include the following sub-steps:
s11, when the first communication part establishes communication connection with the preset device, the third firmware version number sent by the device is received;
s12, judging that the first firmware version number is the same as the third firmware version number;
s13, if yes, establishing communication connection with a preset second chip through a second communication part;
and S14, acquiring the second firmware version number sent by the second chip.
In the embodiment of the invention, when the first chip is installed on the equipment, the first chip can establish communication connection with the equipment through the first communication part and acquire the third firmware version number of the equipment through the connection channel; then judging whether the obtained third firmware version number is the same as the first firmware version number of the third firmware version number; if yes, the firmware of the first chip is represented as the latest firmware, and the first chip records that the firmware of the first chip is the latest firmware. At this time, the first chip may inquire whether a second chip exists in the device; if the firmware version number exists, the second communication part is started to access a second chip in the device through a printer bus or a preset protocol (such as IIC, spi, ISO14443B, wifi, Bluetooth and the like), and a corresponding second firmware version number is obtained to perform subsequent firmware updating judgment.
Further, in this embodiment of the present invention, step 201 further includes:
s15, when the first firmware version number is smaller than the third firmware version number, obtaining the third firmware information of the device;
s16, the first firmware information is updated with the third firmware information.
In the embodiment of the present invention, when the first firmware version number is smaller than the third firmware version number, it indicates that the first chip is an un-updated chip, and at this time, the first chip may be updated through the third firmware information recorded in the device.
In practical applications, the first communication part may be a microcontroller, such as stm8/stm 32/NC-8/NC-10. The first communication section is determined as its type mainly according to the model, kind, and the like of the device. The second communication part may be a bluetooth chip, a wifi chip, or the like, and may be specifically set according to a protocol.
after the first chip obtains the second firmware version number of the second chip, the first firmware version number and the second firmware version number can be compared, and when the first firmware version number is judged to be larger than the second firmware version number, the firmware version representing the first chip is higher than the firmware version of the second chip; at this time, the first chip may start the second communication unit to send a programming instruction to the second chip according to a preset protocol, and update the latest firmware information carried by the first chip into the second communication unit of the second chip, and the second communication unit of the second chip may update the firmware information in the first communication unit of the second chip by using the firmware information of the first chip.
in step 205, the first firmware information is updated with the second firmware information.
In the embodiment of the present invention, when the first firmware version number is smaller than the second firmware version number and the second firmware version number is the same as the third firmware version number, the firmware of the second chip is characterized as the updated firmware. At this time, the firmware information of the first chip may be updated by the second firmware information of the second chip.
In practical application, taking a printer as an example, a first chip with upgraded firmware is installed in the printer, and after the first chip establishes a communication connection with the printer, the printer sends a third firmware version number of the printer to the first chip. The first chip judges whether the first firmware version number of the first chip is the same as the third firmware version number, if so, the second communication part is started to access a second chip in the printer through a printer bus or a preset protocol to obtain a corresponding second firmware version number, and whether the first firmware version number is greater than the second firmware version number is judged; if so, the second communication part sends a programming instruction to the second chip through a preset protocol, and updates the latest firmware carried by the second communication part into the second communication part of the second chip. The second communication unit of the second chip updates the firmware information in the first communication unit of the second chip itself with the latest firmware information. According to the embodiment of the invention, only one updated chip is required to be installed in the printer, and the chip can automatically update the firmware to other chips in the printer. Therefore, chips with old firmware do not need to be recycled, labor cost is greatly reduced, and upgrading risks caused by continuous updating of the printer are solved.
It should be noted that the time for updating the firmware by the chip is not limited, and when the chip is in the power-on state, the chips can search for the chip currently having the latest firmware by mutually interacting data. When the chip of the latest firmware is locked, the chip actively and directly upgrades other chips through a preset protocol.
Furthermore, when the firmware is updated, the power is suddenly cut off, the chip will automatically roll back to the last version, and the firmware update of the chip is performed again when the power is next.
Further, in the embodiment of the present invention, the chip with the old version firmware may be installed in the device with the chip with the new version firmware, so as to update the firmware.
Furthermore, the embodiment of the invention can also be used for judging whether the chip needs to be upgraded or not, placing the chip into the equipment, if the equipment reports an error, representing that the firmware version of the chip is not consistent with the firmware version of the chip recorded by the equipment, and judging that the chip needs to be upgraded.
According to the embodiment of the invention, the first chip with the latest firmware information is installed on the equipment, so that the firmware information of the second chip on the equipment is automatically updated, and the chip needing firmware upgrading does not need to be replaced or returned to a factory for upgrading again. The labor cost is reduced, and the customer experience is improved.
