The embodiment of the present invention is further described in attached drawing.
Based on above-mentioned purpose, on the one hand the embodiment of the present invention proposes a kind of for CPLD brush under server B MC environment
The method newly tested automatically realizes the automatic test that CPLD refreshes by executing test script under BMC system.Of the invention
Method the following steps are included:
Step s1: it obtains pre- refreshing frequency and defines the variable for indicating current refreshing frequency；
Step s2: judge whether current refreshing frequency is equal to the pre- refreshing frequency；
Step s3: it is not equal to the pre- refreshing frequency in response to the current refreshing frequency, executes CPLD refreshing instruction simultaneously
It saves and refreshes log；
Step s4: keyword is read from the refreshing log；
Step s5: in response to reading Flushing success keyword, current refreshing frequency is made to add 1 and executing CPLD version querying
Instruction and return step s3, and refresh failure keyword in response to reading, currently refresh log in terminal output and terminate
Test；
Step s6: it is equal to the pre- refreshing frequency in response to the current refreshing frequency described in step s3, terminates test.
In some embodiments, the method also includes: before performing the testing, by CPLD firmware and execute the method
Test script be copied under BMC system, and run the test script.
In some embodiments, the method also includes: before running the test script, by instruction by the survey
This permission of training is revised as readable writeable executable permission.
In some embodiments, the step s1 includes: to read the pre- refreshing frequency that user inputs from keyboard.One
In a little embodiments, the step s5 includes: in response to reading Flushing success keyword, by Flushing success keyword and after adding 1
Current refreshing frequency be saved in another document.In some embodiments, the step s5 further include: execute CPLD version and look into
After asking instruction, the CPLD version information inquired is saved in another document.In some embodiments, the CPLD brush
New command is depending on compiling generated executable file.In some embodiments, the CPLD version querying instructs basis
Depending on hardware design circuit.
The following are according to one embodiment of present invention, as shown in Figure 1, CPLD firmware and test script are copied first
Under to BMC system /tmp file in；Then Telnet BMC system, execute test script to refresh CPLD, including
It is readable writeable executable permission using instruction modification test script permission and runs test script under current file folder；Most
Afterwards, it after refresh testing, reads and refreshes the contents such as log to analyze test result.
In some embodiments, test script program flow diagram is as shown in Fig. 2, steps are as follows:
(1) a file CPLD_Test_Log is created first at current directory/tmp before surveying operation test script
To store test log, if file of the same name is existing, the content in Delete Folder and file, and a newly-built file
Folder is named as CPLD_Test_Log；
(2) the pre- refreshing times N of input is read from keyboard；
(3) variable i for indicating current refreshing frequency is defined, i initial value is 0；
(4) judge whether current refreshing frequency is equal to pre- refreshing frequency, if so, (10) are executed, if otherwise holding (5)；
(5) CPLD refreshing instruction is executed, and using sentence is redirected, log will be refreshed and be saved in CPLD_Test_Log text
Under part folder, it is named as CPLD_Test_Logi.txt, wherein variable i is current refreshing frequency.Specific instruction format are as follows: CPLD brush
New command > > ./CPLD_Test_Log/CPLD_Test_Log $ i.txt, CPLD refreshing instruction can be held according to caused by compiling
Depending on style of writing part.
(6) read keyword from ./CPLD_Test_Log/CPLD_Test_Log $ i.txt, judge whether refresh at
Function.Wherein keyword is a specific character string, if reading Flushing success keyword, current refreshing frequency adds 1, and will refresh at
Function keyword and current refreshing frequency are input to together in ./CPLD_Test_Log/CPLD_PASS.txt document, are then executed
Step (7), it is no to then follow the steps (9), wherein reading keyword specific instruction are as follows:
Cat./CPLD_Test_Log/ " CPLD_Test_Log $ i " .txt | grep keyword > > ./CPLD_Test_Log/
CPLD_PASS.txt；
(7) CPLD version querying instruction is executed, and result is output to ./CPLD_Test_Log/CPLD_PASS.txt text
In part.Concrete operations instruction are as follows: CPLD inquiry instruction > > ./CPLD_Test_Log/CPLD_PASS.txt, CPLD inquiry instruction
Depending on hardware design circuit.
(8) go to step (4)；
(9) output is current in the terminal refreshes error log；
(10) terminate.
In some embodiments, whether tester meets engineering according to the refreshing log analysis CPLD refurbishing procedure of acquisition
It is required that.For example, not occurring refreshing failure phenomenon or refreshing unsuccessfully is only small probability thing after repeatedly refreshing to CPLD
Part then illustrates that used CPLD refurbishing procedure meets engine request；If it is more universal to refresh failure phenomenon, illustrate that there are it
