[ first embodiment ] A method for manufacturing a semiconductor device
As shown in fig. 1, a first embodiment of the present invention provides a program updating method, for example, including steps S11 to S19.
Step S11: receiving a program updating instruction, and acquiring a current operating address according to the program updating instruction;
step S13: determining a current storage area corresponding to the current running program based on the current running address;
step S15: receiving a target updating program, and solidifying the target updating program into a target storage area corresponding to a target operation address, wherein the target storage area is different from the current storage area;
step S17: replacing the current operation address corresponding to the current storage area with the target operation address; and
step S19: and responding to a first reset instruction, and loading and operating the target updating program from the target storage area according to the target operation address.
In step S11, for example, the receiving card receives a program update instruction issued by the upper computer, and reads the current operating address from the address register. The address register mentioned is, for example, WBSTAR (warm boot address register), and the current operating address mentioned is, for example, an operating address corresponding to a currently operating program, and the current operating address is specified by the address register.
In step S13, the current storage area is, for example, a storage area in which the currently running program is stored, for example, a plurality of program storage areas are provided in a Flash memory connected to the FPGA, and the current storage area in which the currently running program is stored can be determined based on the read current running address.
In step S15, for example, the receiving card receives the target update program issued by the upper computer, and stores the target update program in a target storage area corresponding to the target operation address, where the target storage area is different from the current storage area in which the current operation program is stored.
In step S17, the current operating address specified by the address register is modified to the target operating address corresponding to the target storage area, for example.
In step S19, for example, in response to the first reset instruction, the FPGA of the receiving card jumps to the target storage area to load the target update program according to the target operation address specified by the address register by reading the data in the address register after restarting. The first reset instruction is, for example, an IPROG instruction, the FPGA resets the logic except the reconfiguration function after responding to the IPROG instruction, loads a target update program into a target storage area according to a target operation address specified by an address register, and operates the target update program after the loading is completed, thereby updating the program.
Therefore, a program operation area and a program storage area are not distinguished, the current storage area and the target storage area are both a program storage area and a program updating area, when the program is updated, program data do not need to be erased and written for many times, and the program updating can be realized only by modifying the current operation address into a target operation address corresponding to the target updating program, for example, modifying the address stored in an address register into the target operation address corresponding to the target updating program, so that the efficiency of the program updating can be improved, and the method is suitable for application scenarios of larger program files.
The aforementioned receiving card is, for example, a scanning card for carrying an LED display screen in an LED display screen control system.
Further, step S11, for example, further includes: loading a boot entry of the backup program based on the starting address; jumping to a first operation address specified by an address register according to the loaded boot entry to load a first program from a first storage area corresponding to the first operation address; and responding to the successful loading of the first program, and running the first program. It is to be understood here that the first operating address is referred to as the aforementioned current operating address, the first program is referred to as the aforementioned current operating program, and the first memory area is referred to as the aforementioned current memory area. Or,
step S11 is preceded by, for example: loading a boot entry of the backup program based on the starting address; jumping to a first operation address specified by an address register according to the loaded boot entry to load a first program from a first storage area corresponding to the first operation address; and responding to the loading failure of the first program, jumping to the starting address to load and run the backup program from a storage area corresponding to the starting address. It is to be understood that the aforementioned starting address is used as the aforementioned current operating address, and the aforementioned backup program is used as the aforementioned current operating program and the memory area corresponding to the aforementioned starting address is used as the aforementioned current memory area. Or,
step S11 is preceded by, for example: loading a boot entry of the backup program based on the starting address; jumping to a first operation address specified by an address register according to the loaded boot entry to load a first program from a first storage area corresponding to the first operation address; in response to the first program loading being successful, running the first program; replacing the first operating address stored in the address register with a second operating address; and responding to a second reset instruction, reading and operating a second program from a second storage area corresponding to the second operating address. It is to be understood here that the second operating address is referred to as the aforementioned current operating address, the second program is referred to as the aforementioned current operating program, and the second memory area is referred to as the aforementioned current memory area.
Specifically, as shown in fig. 2, for example, the FPGA may be powered up to load a program before performing a program update. The FPGA is connected with an external memory, for example, a Flash memory, the external memory stores a backup program, in the initial power-on stage, for example, a boot entry of the backup program is loaded from a start address, the start address is, for example, an address 0, wherein the boot entry of the backup program occupies, for example, 100 bytes and includes a first operating address specified by an address register. The backup program mentioned is for example the Golden program.
Because the program is loaded for the first time, the Failback command is not satisfied, when the boot entry of the backup program is loaded, jumping to the first running address specified by the address register, and the first storage area corresponding to the first running address stores the first program, and loading the first program.
If the first program is loaded successfully, the first program is executed, where the first program is, for example, a currently-executed program in the program updating method, the mentioned first running address is, for example, a current running address in the program updating method, and the mentioned first storage area is, for example, a current storage area in the program updating method.
If the first program loading fails, for example, a CRC check fails or a Watchdog detects a program error, the FPGA triggers, for example, a Failback command, jumps to a start address, a backup program of the first program is stored in a storage area corresponding to the start address, and the loading and running of the backup program is performed, that is, the Golden program is loaded and run. The starting address is, for example, address 0, at this time, the backup program is, for example, the currently running program described in the program updating method, the mentioned starting address is, for example, the currently running address described in the program updating method, and the mentioned storage area is, for example, the current storage area described in the program updating method.
Therefore, when the FPGA is electrified to load the running program, the boot loader does not need to be loaded firstly, and the jump loading of the running program can be realized only by loading the boot item of the backup program, so that the loading efficiency can be improved, and the starting address can be returned to load the complete backup program when the loading fails, thereby ensuring the normal starting of the hardware system.
The FPGA further comprises a second storage area for storing a second program, for example, when the first program is loaded successfully and the second program needs to be loaded in the second storage area by jumping to, the first running address specified by the address register is modified to be a second running address corresponding to the second storage area, and the FPGA jumps to the second storage area to read and run the second program in response to a second reset instruction. Wherein, the second reset instruction mentioned is an IPROG instruction. In this case, the second program is, for example, the currently running program described in the program updating method, the mentioned second running address is, for example, the currently running address described in the program updating method, and the mentioned second storage area is, for example, the currently storage area described in the program updating method. In short, when a program jump is required, the address stored by the address register is modified, and the program jump is completed in response to the IPROG instruction.
It should be noted that, for example, the FPGA may further include a plurality of program storage areas, and is not limited to the program storage areas listed in the above embodiments, the number of the specific program storage areas may be set according to the needs of the user, and each program storage area may store and load a program of a corresponding version.
Therefore, the mutual skip among the program areas can be realized, only the specified address of the address register needs to be modified and the skip is carried out in response to the reset instruction, the switching among the version program areas is convenient, the program updating efficiency is improved, and meanwhile, a user can set the number of the program storage areas according to the hardware storage space.
Further, after the program update is completed, if it is necessary to return to the previous version program for loading, for example, a program rollback instruction may be issued by the upper computer, the receiving card receives the program rollback instruction, modifies the target running address specified by the address register to an initial running address, such as the aforementioned starting address, the first running address, or the second running address, and in response to the second reset instruction, jumps to a storage area corresponding to the initial running address to load and run the running program before the update.
Specifically, after step S19, for example, the method includes: receiving and responding to a program backspacing instruction, and modifying the target operation address into the first operation address; and responding to the second reset instruction, and loading and operating the first program from the first storage area corresponding to the first operating address. Or,
after step S19, for example, it includes: receiving and responding to a program backspacing instruction, and modifying the target operation address into the second operation address; and responding to the second reset instruction, and loading and operating the second program from the second storage area corresponding to the second operating address. Or,
after step S19, for example, it includes: receiving and responding to a program backspacing instruction, and modifying the target operation address into the aforementioned initial address; and responding to the second reset instruction, and loading and running a backup program from the storage area corresponding to the starting address.
In summary, in the program updating method provided in this embodiment, a current storage area corresponding to a current running program is determined by reading a current running address, the updated program is received and stored in a target storage area different from the current storage area, the current running address is modified to be the target running address, so that the target updated program is loaded and run in the target running area, and the program running area and the program storage area are not distinguished, where the current storage area and the target storage area are both the program storage area and the program update area, and when performing program update, there is no need to perform multiple erasing and writing of program data, and only the current running address corresponding to the current storage area is modified to be the target running address of the target updated program, so as to implement program update, and therefore, the efficiency of program update can be improved, and the method is applicable to an application scenario of a larger program file; the storage area corresponding to the initial address stores the backup program, the backup program is loaded before program updating and then jumps to the specified address, a boot loader is not required to be loaded after each power-on, the loading efficiency is improved, the initial address is returned when loading fails, and the backup program with complete loading is loaded, so that the normal starting of the hardware system is ensured; after the program is updated, if the program needing to be returned to the initial operation is needed, the target operation address can be modified to be the operation address corresponding to the initial operation program, and the reset instruction is responded, the program needing to be returned to the storage area corresponding to the operation address is jumped to load the initially operated program, the storage space of the backup program of the previous version is not needed to be increased, and the hardware cost is saved.
