. filename : Cross-device link . The file you are trying to make a link to is located on a different physical device. The solution is to create a symbolic link . directory_name is a directory . You are trying to make a link to a directory. Check the pathname for the file. ln: filename : File exists . A file with the same name as the linkname already exists in the destination directory. Use a different name for the linkname.

... I do have a problem with the realtime capabilities of Linux. I wrote a loadable driver which uses the RealTimeClock to generate periodic interrupt at a frequency of 1024Hz. With each interrupt the driver increments an internal counter. The 'read' function of the driver returns simply that counter. Next I wrote a realtime task (with the highest priority) which read that RTC continuously. This tasks checks if the read counter is incremented by one between two read calls. ...
