Detailed Description
The invention is described in further detail below with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting thereof. It should be further noted that, for convenience of description, only some, but not all of the structures related to the present invention are shown in the drawings.
Example 1
Fig. 1 is a flowchart of an online upgrade method for a programmable power supply according to a first embodiment of the present invention, where the embodiment is applicable to online upgrade of the programmable power supply, and particularly provides an effective and convenient online upgrade method for a programmable power supply of a burn-before-paste type.
S110, erasing the programming area of the target programmable power supply.
The data size of the target programmable power firmware information is fixed and smaller than a preset value.
Firmware information refers to programs written into EROM (Eraseable Read Only Memory, erasable read-Only Memory) or EEPROM (Electrically Erasable Programmable Read-Only Memory), electrically erasable programmable read-Only Memory). In this embodiment, the firmware information refers to a program written in a programming area of the programmable power supply to realize online upgrade of the programmable power supply.
The programming area refers to a flash area in the target programmable power supply, which is specially used for storing firmware information.
The preset value may refer to a preset value for evaluating the data size of the firmware information, and is typically a relatively small value, such as several hundred. The method of the present embodiment can be used for online upgrade as long as the flash area for storing firmware information is relatively small. For example, taking a preset value of 500 bytes as an example, if the data size of the firmware information of the target programmable power supply is less than 500 bytes, such as the firmware information size of the programmable digital pwm buck power supply XRP7724 is fixed 448 bytes and less than 500 bytes, the method of the embodiment may be used to upgrade the target programmable power supply (such as the digital pwm buck power supply XRP 7724) online.
S120, acquiring a target configuration file of the target programmable power supply, and writing firmware information corresponding to the target configuration file into the programming area.
The target configuration file refers to a file containing a plurality of parameter configuration information, and in this embodiment, the target configuration file may specifically refer to a file including firmware information of the target programmable power supply, which is used as a basis for configuring the target programmable power supply.
After the target configuration file of the target programmable power supply is obtained, the target configuration file is analyzed, and after firmware information corresponding to the target programmable power supply is obtained, the firmware information is directly written into a programming area preset by the target programmable power supply, so that the online upgrading of the target programmable power supply is realized.
Furthermore, on the basis of the above technical solution, the online upgrade method of the programmable power supply provided in this embodiment further includes: and carrying out data verification on the written firmware information.
When the data verification is performed on the written firmware information, the data verification can be realized by performing one comparison between the data written in the firmware information of the programmable power supply and the corresponding data in the configuration file, if the comparison results are consistent, the data verification is successful, if the comparison results are inconsistent, the data verification is failed, and at the moment, the re-programming operation can be performed on line.
In an alternative embodiment, after the firmware information corresponding to the target configuration file is written into the writing area, the written firmware information may be subjected to data verification. That is, after all the firmware information corresponding to the target configuration file is programmed into the programming area of the target programmable power supply, data verification is performed on all the firmware information in a unified manner. And if the verification fails, re-writing all firmware information corresponding to the target configuration file.
In another alternative embodiment, when the firmware information corresponding to the target configuration file is written into the writing area, data verification may be performed on the written firmware information. That is, when the programming operation of the firmware information is executed, the data verification is performed for the firmware information data corresponding to each programming operation. For example, taking two bytes of firmware information to be written each time as an example, the two bytes of firmware information are checked for data immediately after each writing.
The failure of the burn-in is unavoidable, and the prior art cannot determine whether the burn-in fails until the test is performed after the welding of the device is completed, and also consumes unnecessary time and effort of the tester. Once the burning fails, the chip needs to be removed to be burned by a special burner and then mounted back, so that the time for producing the equipment is additionally increased, and a great deal of time and energy are wasted.
According to the technical scheme, the written firmware information is subjected to online data verification, so that the data accuracy of the firmware information written into the programmable power supply is ensured, and the labor cost and energy are greatly reduced.
As an optional implementation manner, the data verification of the written firmware information may be specifically:
determining a first data accumulation sum of the written firmware information;
determining a second data accumulation sum corresponding to the written firmware information in the target configuration file;
and carrying out data verification on the written firmware information according to the first data accumulation sum and the second data accumulation sum.
The first data accumulation refers to the data accumulation sum of firmware information written into the target programmable power supply; the second data accumulation sum refers to the data accumulation sum of the firmware information in the target configuration file.
After writing the firmware information corresponding to the target configuration file into the programming area, and then performing data verification on the written firmware information, wherein the first data accumulation sum refers to the data accumulation sum of all the firmware information written into the programming area of the target programmable power supply; the second data accumulation sum refers to the data accumulation sum of all firmware information in the target configuration file.
When the firmware information corresponding to the target configuration file is written into the programming area, under the condition that the written firmware information is subjected to data verification, the first data accumulation sum refers to the data accumulation sum of the firmware information written into the programming area of the target programmable power supply at the time; the second data accumulation sum refers to the data accumulation sum of the firmware information corresponding to the current write operation in the target configuration file.
If the first data accumulation sum is consistent with the second data accumulation sum, the data check is successful; if the first data accumulation sum is inconsistent with the second data accumulation sum, the data check fails.
The mode based on data accumulation and data verification ensures the data accuracy of firmware information written into a programmable power supply, and reduces the time complexity and the space complexity of data verification.
Further, if the data verification fails, the operation of erasing the programming area of the target programmable power supply, obtaining the target configuration file of the target programmable power supply, and writing the firmware information corresponding to the target configuration file into the programming area is returned, that is, the operation as described in S110-S120 is executed.
In particular, if it is I 2 When the problem of the C (Inter-Integrated Circuit, built-in integrated circuit) bus leads to transmission errors, during the firmware information programming operation, the continuous writing operation can be interrupted in the address interval of the programming error, and the programming address of the programming error and the area behind the programming address can be reselected.
In an alternative embodiment, if the data verification fails, the firmware information re-programming times are counted. If the firmware information re-programming frequency is greater than a preset frequency threshold, prompting that the online upgrade of the target programmable power supply fails; and if the re-programming times of the firmware information are smaller than or equal to a preset times threshold, returning to execute the operation of erasing the programming area of the target programmable power supply, obtaining the target configuration file of the target programmable power supply, and writing the firmware information corresponding to the target configuration file into the programming area.
The preset frequency threshold value is a value which is preset according to actual working requirements and used for evaluating the re-programming frequency of the firmware information.
According to the technical scheme, the number of times of re-programming of the firmware information is judged, so that the condition that the re-programming is continued under the condition that the long-time verification is unsuccessful is avoided.
According to the technical scheme, the programming area of the programmable power supply is erased, and the firmware information is written into the programming area, so that the programmable power supply can be updated on line, the programming is completed by using an additional programming tool after disassembly, the equipment production efficiency is improved, and the labor cost is reduced. If there are multiple programmable power supplies to be programmed at the same time, the power-down restarting operation of the device may be performed after all the firmware information corresponding to the multiple programmable power supplies is programmed.
