Hello everyone,
I have a Linux thread which read/write to a device connected by usb port & I
would like to bring it to Xenomai realtime by using rtdm library. What I wonder
is the difference between the functions of rtdm & those of POSIX Xenomai skins,
if the goal is only to bring the realtime properties to the process.
For example, rt_dev_open() (of rtdm) & open() (of POSIX Xenomai). When I use
open() of POSIX Xenomai, it works fine, but with rt_dev_open(), it returns -19
as output, with the same port address:
#define ENODEV 19 /* No such device */
And then, I don't really understand the purpose of making a serial
communication become "realtime", which means that making the read() procedure
more deterministically?
Best regards,
Huy Cong
