Keil Error: ST-LINK USB communication error
Today, when downloading the program with stlink-v2, there was st-link USB communication error. This problem suddenly appeared. I found many solutions on the Internet, but they can’t be used. My solutions are given below for reference only.
If there is a problem as shown in the figure below:
We can solve this problem by re brushing the firmware. you can download the stlink online.
It is very easy to upgrade the firmware of ST-Link. If the ST-Link can be used normally, please do not come to upgrade easily. Here you can open our ST-Link package, there is a zip package inside: ST-Link firmware upgrade software.zip, you can see after decompression.
For windows computers, we go directly to the windows folder and click ST-LinkUpgrade.exe:
The opened interface is as follows:
At this time, we need to connect st link to the computer through USB. After connecting, click the device connect button on the interface,
if the connection is successful, the prompt message in the following interface will appear:
Note: if an error is reported when brushing firmware: Communication error with ST-Link .Try to start it. We can solve this problem by unplugging stlink and then continuing to update the firmware

quartus 13 利用IP核 NCO 生成dds出现Megawizard error解决
The following errors occurred when using NCO in IP core to produce DDS:
MegaWizard Error MegaCore Function Generation Error IP Functional Simulation Model Creation Failed. The following error was returned;Error: Quartus ll 32-bit Analysis & Synthesis was unsuccessful. 1 error, 2 warnings
I checked many methods on the Internet and cracked the IP core, but the problem still appears when quoting the IP core. After my actual measurement, it may be due to the problem of version 13.
Suggestion: it may be due to the problem with version 13. After installing version 18 of quartus, I can normally use fir # NCO and other IP cores
You can see that I modified the values of clock rate and desired output freq, but the waveform of the following magnet has not changed, but my IP core has been cracked.
After installing Quartus # 18, you can see that the magnetic waveform has a pulse at 6mhz, which is consistent with the output frequency we designed

ERROR OGG-01028 Detect partial pdata at rba xxxxxx without coinciding crash recovery marker record
Ogg version: 11.2.1.0.13
Fault description:
The Ogg extraction process was abended because the database instance was automatically restarted in the early morning
Ogg process down view the $GGATE_HOME/ggserr.log. The errors are as follows:
ERROR OGG-01028 Detect partial pdata at rba xxxxxx without coinciding crash recovery marker record in log with seqno = xxxxxx
The contents of log error reports are as follows:
error ogg-01028 detects partial pdata at RBA XXXXXX, which does not coincide with the crash recovery mark record in the log with seqno = XXXXXX
Cause of failure:
When the classic extraction fails in the log writing process, there is incomplete extraction, which will lead to the downtime of the extraction process
Troubleshooting:
1. Try to restart the extraction process, which will be started, generally without any problems, and will continue to process the logs
2. If restarting the extraction process fails, add the following parameters to the extraction process to skip incomplete log data and restart the extraction process
tranlogoptions _skipincompletelogdata
