Hi,
I have been trying to open a character device and getting the following

error . It > open("/dev/mychardev", O_RDONLY)        = -1 EACCES
(Permission denied)

What do I have to change my permission mode ??
Please help. Thanx in advance .

Can you please tell what are the permissions you have assigned to
application which is producing this strace. Also, which user mode are you
in when you execute it.

Generally , it can be because lack of enough permissions to read app, or
because the driver associated with you char dev is returning this error
code.

Thats my two pence.
