Detailed Description
It should be noted that, in the present application, the embodiments and features of the embodiments may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.
In order to make the technical solutions better understood by those skilled in the art, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only partial embodiments of the present application, but not all 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 application.
It should be noted that the terms "first," "second," and the like in the description and claims of this application and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It should be understood that the data so used may be interchanged under appropriate circumstances such that embodiments of the application described herein may be used. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
It will be understood that when an element such as a layer, film, region, or substrate is referred to as being "on" another element, it can be directly on the other element or intervening elements may also be present. Also, in the specification and claims, when an element is described as being "connected" to another element, the element may be "directly connected" to the other element or "connected" to the other element through a third element.
For the field of chips, such as FPGA chips, most of the FPGA chips are based on an SRAM (Static Random-Access memory) structure, and data in the SRAM is lost when power is off, so after the FPGA is powered on, configuration data must be loaded into the SRAM of the FPGA by an external configuration circuit, the FPGA can normally operate, and the configuration chips are generally Flash chips, that is, the configuration data operating in the FPGA is stored in the Flash chips. As shown in fig. 1, an external circuit includes a configuration device, which forms an external configuration circuit, the external configuration circuit loads configuration data into an SRAM of the FPGA, the configuration data in the SRAM is configured to control an internal programmable logic, an internal register, and an input/output register of the FPGA to initialize, drive enable the input/output register, and the like, of the FPGA, and then the FPGA enters a user mode.
Fig. 2 shows a principle of adopting a simulator to solidify a program, after compiling is completed by using a compiler, logic data for downloading may be generated, the logic data may be directly downloaded to an internal SRAM of an FPGA by using the simulator for online operation (data in the SRAM is lost when power is down), the logic data may also be solidified in a hardware circuit (data in the hardware circuit is not lost when power is down), and when the logic data needs to be solidified in the hardware circuit, the logic data needs to be loaded into a Flash chip. When the simulator is used for solidifying logic data, the simulator downloads a section of logic data (data for receiving the simulator and reading and writing a Flash chip) containing an upgrading module into an SRAM (static random access memory) of an FPGA (field programmable gate array), and then the logic data can be indirectly written into the Flash chip through the section of logic data simulator, and the remote online upgrading realized in the practical application process cannot be necessarily upgraded by using the simulator, so that the upgraded logic data can be written into the Flash chip by using a serial port, an Ethernet port or other communication interfaces with reference to the process of solidifying the logic data by the simulator.
Referring to the principle in fig. 2, an upgrade module may also be added in the FPGA to receive upgraded data, and then write the upgraded data into the Flash chip, as shown in fig. 3, the principle in fig. 2 is used in fig. 3 to improve the method in fig. 1, an external device sends an upgrade software package to the FPGA, and then the FPGA sends the upgrade software package to the Flash chip, however, the method of remote upgrade of the FPGA in fig. 3 has a large defect, if a power failure occurs during the upgrade process, the program is only upgraded partially, the original stored program is also damaged, and if the power is re-turned on, the program cannot be restarted, and the upgrade cannot be performed again.
In order to solve the above problems, as shown in fig. 4, it may also be tried to add an external memory (e.g., SRM or DDR (Double data Rate, Double-think synchronous dynamic random access memory)) to the FPGA on the hardware to temporarily store the upgraded data, and the like, when all the upgrade software packages are completely received and checked to be normal, and then write into the Flash chip.
As mentioned in the background, in order to solve the above problem, in the prior art, when a power failure occurs during a process of remotely upgrading a software program of a processor chip, the upgrading cannot be completed.

step S102, upgrading the second type system by adopting the upgrading software package;
step S103, if the power failure occurs in the process of upgrading the second type system, determining whether the second type system needs to be upgraded again, and if the second type system needs to be upgraded again, controlling the first type system again to transfer the upgrade software package to the storage space of the second type system.
In the method, an upgrade software package is obtained first, the first type system is controlled to transfer the upgrade software package to a storage space of the second type system, data in the first type system is not changed under the condition that the processor chip is powered off, then the second type system is upgraded by the upgrade software package, and finally, if the power off condition occurs in the process of upgrading the second type system, whether the second type system needs to be upgraded again is determined, and the first type system is controlled again to transfer the upgrade software package to the storage space of the second type system under the condition that the second type system needs to be upgraded again.
