It should be noted that all statements for using " first " and " second " are for differentiation two in the embodiment of the present invention The non-equal entity of a same names or non-equal parameter, it is seen that " first " " second " only for the convenience of statement, does not answer It is interpreted as the restriction to the embodiment of the present invention, subsequent embodiment no longer illustrates this one by one.

It should be noted that in an embodiment of the present invention, the basic function of UID key includes that short-press pressure UID key comes Display UID LED bright is gone out and long-pressing (such as six seconds) reaches the function of BMC resetting.After user presses power knob, Computer booting starting BIOS simultaneously executes startup self-detection POST process, during computer is in and executes POST, from PCH chip Middle acquisition computer executes POST information code caused by POST process, is sent to phase by CPLD after then converting information code The LED (that is: POST CODE LED) answered, to show corresponding POST decoding process.Due to the design of server master board, in itself There will be 8 POST CODE LED of design.

In an embodiment of the present invention, the first LED refers to that POST CODE LED, the 2nd LED refer to UID LED.Wherein, UID refers to Unit identification (user identity proves).

According to an aspect of the present invention, the embodiment of the present invention proposes a kind of method for showing CPLD version, such as Fig. 1 institute Show, may include executing following steps by CPLD: S1 sends the signal and use for showing POST process to the first LED In the signal of display CPLD version；S2 receives the pressing instruction of UID key；S3 judges that the pressing instructs according to pressing duration It whether is the first pressing instruction；S4 is that first pressing instructs in response to pressing instruction, then controls the first LED It is shown according to the signal for showing CPLD version.

Method disclosed by the invention can nor affect on existing UID key and answer in the design architecture for not changing existing hardware Under some functional conditions, by the way that CPLD version information is encoded to CPLD in advance, when receiving command adapted thereto, according to customized Turning on/off for corresponding POST CODE LED is controlled, and then CPLD version information is shown by POST CODE LED.Such as: it is logical It crosses and controls that corresponding POST CODE LED often goes out, to determine stroboscopic bright and be always on, show corresponding CPLD version.Different CPLD Version can be with customized different POST CODE LED display mode, according to the light on and off situation of different POST CODE LED Obtain corresponding CPLD version.

Below with reference to Fig. 2 shows the flow diagram of method of display CPLD version be described in detail.

Firstly, sending the signal for showing CPLD version to the LED of the signal for receiving display POST process.

It in some embodiments, i.e., can be to after the signal for being used to show CPLD version is sent to POST CODE LED POST CODE LED sends 2 road signals simultaneously, all the way for for showing the signal of POST process, another way is display CPLD editions This signal.And under default situations, POST CODE LED is according to for showing that the signal of POST process is shown.

Specifically, when being encoded to CPLD, according to CPLD version by the volume of corresponding customized control POST CODE LED Code write-in CPLD, then CPLD sends relevant signal to POST CODE LED.

Then, the pressing instruction of UID key is received.

In some embodiments, for user after pressing UID key, CPLD just will receive corresponding instruction, for example, User press UID key when it is a length of less than 3 seconds, CPLD just will receive one instruction user press UID key duration less than 3 Second third press instruction, and then lighting or extinguishing for LED corresponding with UID key is controlled, when UID LED is in OFF state When, CPLD receives third pressing instruction, i.e. control UID LED is lighted, and after then CPLD is received again by third pressing instruction, that is, controls UID LED processed extinguishes.Alternatively, user press UID key when it is a length of more than 6 seconds, at this point, CPLD receive instruction user pressing The duration of UID key is more than the second instruction in 6 seconds, it will issues reset signal to BMC so that BMC is reset.

Next, it is determined that whether pressing instruction is the first pressing instruction.

In some embodiments, the first pressing instruction for instruction user press UID key when a length of be greater than 3 seconds less than 6 Second.

Finally, according to the difference of pressing instruction, CPLD executes different movements.For example, being in response to pressing instruction The first pressing instruction then controls the LED according to described for showing the signal of CPLD version；Refer in response to the pressing It enables not for the first pressing instruction, controls the LED according to described for showing the signal of POST process.

It should be noted that when POST CODE LED shows POST process, pressing that no matter CPLD is received instruction is the Two pressing instructions or third pressing instruction, POST CODE LED continue to show POST process.CPLD receives the first pressing and refers to When enabling, then POST CODE LED is switched to by display CPLD version, i.e. control POST CODE LED by its internal logic According to the signal used for showing CPLD version.

In some embodiments, further includes: when the pressing for receiving the UID key again instructs；Sentenced according to pressing duration Whether the disconnected pressing instruction received again is the first pressing instruction；It is in response to the pressing instruction received again The first pressing instruction then controls the LED and is shown according to the signal for showing POST process.In response to institute Stating the pressing instruction received again is the second pressing instruction, then controls the LED according to described for showing POST process Signal.It is third pressing instruction in response to the pressing instruction received again, then lights or extinguish UID LED.

It should be noted that UID LED can be first lighted during user presses UID key, it is then long super when pushed After spending 3 seconds, POST CODE LED is switched to the state of display CPLD version, and UID LED is the state being remain in the process. When user presses UID key again, UID LED can extinguish, and after then growing when pushed more than 3 seconds, POST CODE LED is cut The state of display POST process is changed to, UID LED is the state for keeping extinguishing.

Specifically, then controlling POST CODE LED after CPLD receives the first pressing instruction for the first time and showing CPLD editions This, user can long-pressing UID key be more than again 3 three seconds and less than six seconds, i.e. CPLD is received again after the first pressing instructs, CPLD will switch the state that POST CODE LED returns to display POST process.At this point, when user's long-pressing UID key is more than six After second, instruction that CPLD is received again is the second pressure instruction, and CPLD will issue reset signal to BMC so that BMC is reset, and And POST CODE LED is controlled according to described for showing the signal of POST process.Namely POST CODE LED is even in aobvious Show the state of CPLD version, can also be switched to the state of display POST process, is may insure in this way when BMC is reset, POST CODE LED may return to the function cresset of the display POST decoding process of most original.

In this way, increasing the display function of CPLD version by using the existing UID button design of server, not changing Any existing hardware design does not change existing general specification yet, successfully reads the CPLD version number on current server.When Research staff or tester are in the soft topic of burning that no any CPLD burning cable or CPLD manufacturer provide, while also not It needs to wait BMC developer, complete exploitation or worries whether BMC is dead there is a situation where hanging, and illegal learn current CPLD Version can efficient and quickly know the CPLD version on current server using method disclosed by the invention.
