The main controller can be preset with upgrade information, wherein the upgrade information can include upgrade time and upgrade version, the main controller automatically obtains an IPMC upgrade program corresponding to the upgrade version from the server through the internet access according to the upgrade time, and automatically upgrades the board card to be upgraded according to the IPMC upgrade program. The main controller can also periodically detect whether the IPMC program is updated, if so, the IPMC upgrading program of the latest version is automatically acquired from the server through the network port, and the board card to be upgraded is automatically upgraded according to the IPMC upgrading program of the latest version. The main controller can also receive the remote instruction information, and according to the remote instruction information, the IPMC upgrading program corresponding to the upgrading version contained in the remote instruction information is acquired from the server through the internet access, or the IPMC upgrading program of the latest version is acquired, and the board card to be upgraded is upgraded.
The programmable logic device is a digital integrated circuit which can independently construct logic functions according to requirements, and the programmable logic device can be internally composed of a programming macro-cell matrix and connected by using metal wires with fixed length.
The main controller may send an upgrade instruction to the programmable logic device through a channel bus (local bus), where optionally, the upgrade instruction includes at least one control word.
And S120, the programmable logic device enters an upgrading mode according to the upgrading instruction and controls the board card to be upgraded to enter a system programming mode.
The programmable logic device receives an upgrade instruction sent by the main controller, enters an upgrade mode according to a control word In the upgrade instruction, and further controls a board card to be upgraded to enter an In System Programming (ISP) mode. For example, referring to fig. 2A, fig. 2A is a schematic diagram of a control word according to an embodiment of the present invention. The control word in fig. 2A includes control bits, where 4 control bits in the control word are used to control whether the programmable logic device enters the upgrade mode, and 1 control bit in the control word is used to control whether the board card to be upgraded enters the system programming mode. Illustratively, if the control position of 4 in the control word is 1, the programmable logic device enters an upgrade mode; and if the control position of 4 in the control word is 0, the programmable logic device exits the upgrading mode. When the control position of 1 in the control word is 0, the programmable logic device controls the board card to be upgraded to enter a system programming mode; and when the control position of 1 in the control word is 1, the programmable logic device controls the board card to be upgraded to exit the system programming mode.

And after each program is written into the flash area by the board card to be upgraded, calculating upgrade verification information of each written program, wherein the upgrade verification information and the standard verification information can be determined based on the same calculation mode. Matching the upgrade verification information with the standard verification information, if the upgrade verification information is the same as the standard verification information, determining that the matching is successful, determining that the command written into the flash area is correct, and continuously writing the next IPMC upgrade program into the flash area; and if the upgrading verification information is different from the standard verification information, determining that the matching fails, and receiving the IPMC upgrading program again by the board card to be upgraded.
