Example 1

The method provided by the first embodiment of the present application may be executed in a single board or a similar computing device. Taking the operation on a single board as an example, fig. 1 is a block diagram of a hardware structure of a single board of an upgrade method according to an embodiment of the present invention. As shown in fig. 1, board 10 may include one or more (only one shown) processors 102 (processor 102 may include, but is not limited to, a processing device such as a microprocessor MCU or a programmable logic device FPGA, etc.), a memory 104 for storing data, and a transmission device 106 for communication functions. It will be understood by those skilled in the art that the structure shown in fig. 1 is only an illustration and is not intended to limit the structure of the electronic device. For example, veneer 10 may also include more or fewer components than shown in FIG. 1, or have a different configuration than shown in FIG. 1.

The memory 104 may be used to store software programs and modules of application software, such as program instructions/modules corresponding to the upgrading method in the embodiment of the present invention, and the processor 102 executes various functional applications and data processing by running the software programs and modules stored in the memory 104, so as to implement the method described above. The memory 104 may include high speed random access memory, and may also include non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory. In some examples, memory 104 may further include memory disposed with respect to processor 102, which may be connected to board 10 via a network. Examples of such networks include, but are not limited to, the internet, intranets, local area networks, mobile communication networks, and combinations thereof.

The transmission device 106 is used for receiving or transmitting data via a network. The specific example of the network described above may include a wireless network provided by a communications provider of the single board 10. In one example, the transmission device 106 includes a Network adapter (NIC) that can be connected to other Network devices through a base station to communicate with the internet. In one example, the transmission device 106 may be a Radio Frequency (RF) module, which is used to communicate with the internet via wireless.

In this embodiment, an upgrade method operating on the above single board is provided, and fig. 2 is a flowchart of the upgrade method according to the embodiment of the present invention, as shown in fig. 2, the flowchart includes the following steps:

step S202, detecting whether a download identifier of a second erasable and editable logic device EPLD program exists in a standby information area for storing state information of a standby storage area, wherein the second EPLD program is an upgrade version of a first EPLD program, the first EPLD program is a version to be upgraded, and the standby storage area is used for storing the second EPLD program;

step S204, if the detection result is yes, the second EPLD program is trial run;

in step S206, the second EPLD program is activated when the trial run of the second EPLD program is successful.

Through the steps, the standby information area used for storing the state information of the standby storage area is divided, the download identification of the second EPLD program of the upgrade version is recorded in the information area, so that the situation that the single board downloads the upgrade version of the first EPLD recently can be known according to the identification, the upgrade version is selected, after the second EPLD program of the upgrade version is obtained, the second EPLD program is not directly activated but is firstly subjected to trial run, and the second EPLD program is activated only after the trial run is successful, so that the second EPLD program after being activated can be ensured to be available. Therefore, the problem that the veneer possibly cannot normally run because the EPLD program is available after being activated cannot be guaranteed in the related technology can be solved, the selection of the upgrade version is realized, and the effect of guaranteeing the starting reliability of the EPLD is achieved.

Optionally, before detecting whether the download identifier of the second EPLD program exists in the spare information area for storing the status information of the spare storage area, the method further includes: receiving an upgrading command which is sent by a Network element Control Processor (NCP) and used for indicating that a first EPLD program of the EPLD is upgraded; according to the upgrading command, acquiring a second EPLD program and writing the second EPLD program into a standby storage area in a memory of the EPLD, wherein the memory is used for storing the EPLD program; and setting a download identifier of the second EPLD program in the spare information area. Wherein, the memory used for the EPLD program can be Flash;

optionally, in the case that the commissioning of the second EPLD program is successful, activating the second EPLD program comprises: under the condition that the trial operation of the second EPLD program is successful, sending a message of successful trial operation to the NCP; receiving an activation command sent by the NCP to activate the second EPLD program; and according to the activation command, activating the second EPLD program by switching the standby storage area to the main storage area, wherein the main storage area is used for storing the first EPLD program. Through the above steps, only after the second EPLD program is successfully commissioned, the storage where the second EPLD program is located is set as the main storage area, so that, if the second EPLD program after being upgraded fails to commissioned, the main storage area and the standby storage area are not switched, so that the single board can continue to run the first EPLD program, and therefore, when the EPLD program after being upgraded is activated and is unavailable, the single board can still run normally.

Optionally, before receiving an upgrade command sent by the NCP for instructing to upgrade the first EPLD program, the method further includes: partitioning a storage area of a memory, wherein the storage area is at least partitioned into: the system comprises an EPLD program, a main storage area for storing the EPLD program, a spare storage area for storing the EPLD program, a main information area for storing the state information of the main storage area and a spare information area for storing the state information of the spare storage area. For example, a Flash storage area for storing an EPLD program on a single board is used, two areas are divided from the Flash storage area as main and standby storage areas of the EPLD program, persistent storage after power failure is realized, and two areas are further divided from the Flash storage area as main and standby information areas of the EPLD program, where the main and standby information areas are mainly used for storing state information of the main and standby EPLD storage areas, including main and standby state flags, version upgrade time, a commissioning flag, a version storage area start address, an upgrade flag, an EPLD version number, a CRC check value, and other information. The main and standby EPLD program selection control can be realized through the partitions.

Optionally, in a case that the commissioning of the second EPLD program is successful, before activating the second EPLD program, the method further includes: judging whether LPC programming identification exists in Flash ISF in the EPLD system; under the condition that the judgment result is negative, updating the second EPLD program into the ISF; the second EPLD program is commissioned in the ISF.

Optionally, before determining whether the LPC writing identifier exists in the Flash ISF in the EPLD system, the method further includes: judging whether a main EPLD identifier exists in the main and standby information areas, if a representative single board is not used for the first time and an operating program exists, judging whether an LPC programming identifier exists in a Flash ISF in an EPLD system; if the judgment result is yes, operating an EPLD program in the ISF; under the condition that the judgment result is negative, updating the second EPLD program into the ISF; the second EPLD program is commissioned in the ISF. If the main/standby information area has no main EPLD identifier, the single board is used for the first time, the EPLD program in the ISF is operated, the EPLD program is updated to the main/standby storage area, and the relevant state information of the relevant main/standby storage area is updated to the main/standby information area.

For example, after the single board is powered on and started, a memory (Flash) for storing the EPLD program is initialized, and the Flash is partitioned. After the first operation program BOOT after the single board is powered on is started, it is first judged whether a main EPLD identifier exists in the partitioned EPLD information area. When the main mark exists, judging whether an LPC programming mark exists, and if the LPC programming mark exists, operating an EPLD in the ISF; if not, the above-mentioned EPLD program of the memory for storing the EPLD program is run while the EPLD program in the ISF is updated. And if the main state mark does not exist, operating the EPLD in the ISF, and updating the EPLD program and the EPLD information area information in the EPLD program memory.

The above-described embodiments achieve the upgrading of the EPLD version by using the effective cooperation of the EPLD and BOOT version information areas.

Optionally, according to the upgrade command, acquiring the second EPLD program and writing the second EPLD program to the spare storage area in the memory of the EPLD for storing the EPLD program includes: downloading the second EPLD program from a storage device (Compact Flash, CF for short) card according to the storage position information of the second EPLD program in the upgrading command; the second EPLD program is written to a spare storage area in the EPLD's memory for storing the EPLD program.

For example, logging in the NCP main control board through a file transfer protocol (ftp) in a network, and transferring the EPLD program upgrade version file to the CF card of the main control board. Then, the system logs in to the NCP through telnet, and issues an update EPLD program command to the board through a Serial Communication Port (S Port for short). The single board carries out downloading processing after receiving the upgrading command, and finally writes the EPLD program upgrading version file into a standby storage area in the EPLD Flash.

For another example, after the downloading is completed, the NCP issues a test run command and an activate command to set the EPLD area for storing the upgrade as the primary storage area, and configures a BOOT selection flag of the BOOT in the ISF. And when the test operation fails, the original EPLD version is used as the main use through a rollback mechanism, and the information of the information area is updated.

The above embodiments are described in detail below with reference to the accompanying drawings by taking EPLD remote upgrade as an example.

The realization of the EPLD remote upgrade function requires the cooperation of the single board BOOT side software, the single board application side software and the NCP application software. The three parts belong to different operation stages and different CPU spaces. The single board BOOT software and the single board application software carry out data communication through the memory, and the single board software (including the BOOT software and the single board application software) carries out data communication with the NCP through the S port. The user interacts with the NCP through telnet/ftp based on TCP/IP protocol, the general block diagram of which is shown in fig. 3.

The implementation process is as follows:

1. and compiling to generate an EPLD program EPZ file, calculating the size and the CRC value of the EPZ file after compiling is finished, and writing the EPZ file into the EPZ file to be used as an LPC download mark (in order to be compatible with the original upgrading mode).

2. After the single board is started, the Flash storing the EPLD program is initialized and partitioned, the partition status is as shown in fig. 4, and the partitioned Flash includes: an information area A, an information area B, an EPLD program storage area A, and an EPLD program storage area B. Then, the single board BOOT software performs EPLD program selection processing. After the single board is electrified, the BOOT is started normally to operate, and EPLD upgrading processing is carried out.

The schematic diagram of the EPLD program in the Flash trial run is shown in fig. 7, and first, EPLD information is obtained from the information area, and then, whether the EPLD program area is trial run is determined according to the information, if not, the main memory area of the EPLD is designated as the running area, if yes, the EPLD trial run identifier is cleared, the EPLD information in the information area is updated, and then, the EPLD area is designated as the running area.

The schematic diagram of the EPLD program in Flash operation is shown in fig. 8, and the version numbers of the areas to be operated (main memory areas or trial operation areas) in the ISF main area and the Flash are obtained, and then, it is determined whether the version numbers are consistent?

If the judgment result is consistent, the EPLD boot area index is obtained, and it is judged whether the EPLD boot area index is the ISF B area according to the index number? If the current time is the area B, closing the EPLD watchdog and triggering the ISF area B to operate, then performing PCIE delocalization, opening the EPLD watchdog and closing the slow and fast reversal timers, then displaying the EPLD result, and starting to operate an EPLD program in Flash at the moment; and if the Flash memory is not the B area, directly reading the EPLD program in the Flash.

Under the condition that the judgment is inconsistent, after an EPLD program of a flash to-be-run area is synchronized to an ISF B area, an EPLD watchdog is closed and the ISF B area is triggered, then PCIE is released and reset, the EPLD watchdog is opened and a slow and fast reverse timer is closed, and then, is it judged whether EPLD runs successfully? When the judgment result is yes, setting the EPLD starting area as an ISF B area, and starting to run an EPLD program in Flash; and if the judgment result is negative, ending the upgrading.

As shown in fig. 9, a schematic diagram of a process of performing remote upgrade on an EPLD by BOOT processing is shown, and status information of the EPLD is obtained, whether the EPLD needs to be remotely upgraded is determined according to the status information, if yes, a related global variable of EPLD upgrade is initialized, an upgrade EPLD request is sent to the NCP, an NCP response is waited, a response is received within 8 minutes, data sent by the NCP is received, after a last packet is sent, a CRC value is checked, EPLD information is updated, and a final upgrade result is sent to the NCP.
