Hi,
I don't know if my problem is specific to RTLinux (I don't think so),
but maybe someone has an answer: I want to use RTLinux to write data to
a device (/dev/ttyI*). So I write a module that create a "periodic"
thread; in this thread, I try to open the device, but the open()
function always tells me "bad file or directory"... I have tried with a
simple file and I also get the error!
This is the first time I write a kernel module and I don't really know
what functions can be used and when, so I would like to know how to open
a file/device while in kernel space.
Thanks in advance.
