Hi All,

 

we are working in BF527 custom board and 2010 Distribution.

we wrote a char driver model for custom board peripherals.

 

There is an issue with the close system call.

 

The kernel close API call is not executed when the close system call is called from user space.

But the fd is same as what we are getting in the open system call.

 

kindly let me what could be the reasons for the issue and how can we debug this issue.

 

Please provide your inputs.

 

With Regards,

Thangaraj.P
