Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 1 and 2, the method for upgrading dual-CPU dual-system program in the present invention includes:
Step S001: integrating upgrade files of a main CPU system and a secondary CPU system into the same upgrade package, namely constructing the upgrade package, starting the main CPU system and the secondary CPU system after constructing the upgrade package, and establishing a reliable management channel for communication after the main CPU system and the secondary CPU system are started;
step S002: the main CPU system is upgraded, namely an upgrade package is downloaded to a cache area, the version is verified, after verification is passed, the erasing Flash partition operation is executed to upgrade the main CPU system, and after the main CPU system upgrade is completed, the system reset restarting is executed; then, the slave CPU system is restarted, and after the master CPU system and the slave CPU system are started, a management channel is built again for effective communication;
Step S003: the slave CPU system initiates software version check immediately, when the master CPU system is updated and the software information of the slave CPU system bound in the file system is different from the local actual version information, the software update is required to be executed, and then the slave CPU system receives a new update file through a management channel and performs Flash partition erasing update on the new version software;
step S004: after the secondary CPU system is upgraded, the associated versions of the secondary CPU system and the primary CPU system are consistent, and the complete machine reset is executed, the primary CPU system and the secondary CPU system are marked to be upgraded.
In this embodiment, in the step S001, in the step of constructing the upgrade package of the master CPU system, the software version information of the slave CPU system and the corresponding file thereof are compiled in advance and stored in the file system of the master CPU system, so as to ensure that the software versions of the master CPU system and the slave CPU system are closely related and packaged as a whole.
In this embodiment, the management channel includes an i_c channel, an SPI channel, and an RPC channel; specifically, when a reliable management channel is established for communication, if the master CPU system fails to establish connection with the slave CPU system within a set time, the complete machine reset operation is actively executed to attempt to restore communication, and the slave CPU system can enter a subsequent software upgrading verification stage on the premise that the slave CPU system has to establish communication with the master CPU system in a starting process.
In this embodiment, during the upgrade of the main CPU system, the upgrade package is received and temporarily stored in the buffer area through a remote communication manner, then a strict version verification is performed, after the verification is passed, the erasing Flash partition operation is performed to upgrade the system, and after the upgrade is completed, the system is automatically triggered to reset and restart.
In this embodiment, after the slave CPU system is normally started and successfully establishes a management communication channel with the master CPU system, a built-in software version checking process is started, through the management channel, the slave CPU system obtains own software version information, and performs version consistency check, once the difference between the version of the master CPU system and the version of the slave CPU system is found, the slave CPU system is triggered to upgrade, an upgrade package file is downloaded to a memory, then an erase Flash partition upgrade step is performed, after the upgrade is completed, the system is reset and restarted, if the verification result shows that the version of the master CPU system is consistent with the version of the slave CPU system, the current system state is maintained, and normal operation is continued, otherwise, the upgrade operation is performed again, so that the version of the master CPU system is consistent with the version of the slave CPU system.
In this embodiment, the device upgrade process of the whole dual-CPU system integrates the two parts, the main CPU system first triggers the upgrade process, downloads the upgrade package to the cache and verifies the version, and then executes the system reset restart after the self upgrade is completed, at this time, the slave CPU system is restarted, and establishes the management channel again after both are started for effective communication. The slave CPU system then initiates a software version check flow, and the software information of the slave CPU system bound in the file system is different from the local actual version information in view of the updated master CPU system, so that the software upgrading flow needs to be executed. And then, receiving a new upgrade file from the CPU system through the management channel, and performing erasure upgrade of the Flash partition on the new version software. After the secondary CPU system is upgraded and the complete machine reset is executed, the complete upgrading process of the complete machine double CPU system is marked to be completed smoothly.
It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
