In the second update mode, if the update link 2 is disconnected from the second joint test workgroup interface 14 and the update link 2 is not electrically connected to the second joint test workgroup interface 14, the update is still to be updated. When the detection module 15 detects that the second joint test working group interface 14 is not electrically connected to the update connection line 2, a second digital signal S2 is detected. The signal is transmitted to the multiplexer 13, wherein the second digit signal S2 can be, for example, 1, and after the multiplexer 13 receives the second digit signal S2, the path between the processing chip set 12 and the complex programmable logic device 11 is opened.

Referring to FIG. 3 and FIG. 4 together, FIG. 4 is a schematic flow chart showing an updating method of the second preferred embodiment of the present invention. As shown in the figure, the updating method of the second preferred embodiment of the present invention is an application. The firmware update system 1 of the complex programmable logic device shown in FIG. 3 is executed by the firmware update system 1 of the complex programmable logic device, wherein the update method further comprises the following steps:

Step S201: It is judged whether the update connection line 2 is electrically connected to the second joint test working group interface 14.

Step S202: The second joint test working group interface 14 is electrically connected to the complex programmable logic device 11 through the multiplexer 13, and a second updated firmware version data 31 is transmitted to the complex programmable logic through the update connection line 2. The device 11 replaces the original firmware version data 111 and completes the update.

Step S201 is performed by the detection module 15. In step S202, the first digital signal S1 is transmitted from the detection module 15 to the multiplexer 13, and the second joint test working group interface 14 is transmitted through the multiplexer 13. Connected to the complex programmable logic device 11 by the update device 3, the second updated firmware version data 31 is transmitted to the complex programmable logic device 11 through the update link 2 instead of the original firmware version 111 and updated. . In addition, in the step S203, in the condition that the update connection line 2 is not electrically connected to the second joint test working group interface 14, the second digital signal S2 is also transmitted from the detection module 15 to the multiplexer 13, thereby performing processing. The chip set 12 is electrically connected to the complex programmable logic device 11 through the multiplexer 13. The steps S204 to S207 are the same as the second preferred embodiment of the second figure (steps S101 to S104), and therefore will not be described again.

In summary, after the firmware update system of the complex programmable logic device provided by the present invention and the update method thereof, the platform path controller can still be transmitted because the server does not have the baseboard management controller. The original firmware version data provided by the complex programmable logic device is directly updated, thereby greatly increasing the convenience of practical use.
