I’m not able to log data to sd card . an error “ **status of the last log: file access error** ” is showing in the data log template. No file is generated in the sd card after trigger is given . is it is the file path issue?

Hi, if you are using Fw26 due to a bug, you need to create the folder yourself.  
So by default you have to create the folder CSV\_Files in /media/sd/.

Use an SSH program like PuTTY. The command is “md CSV\_Files”, while you are in the “media/sd” folder. For example:

You can use an FTP client such as FileZilla to create and view files. Just don’t forget to enable FTP in the web interface.
