Hi
I'm still having some problems with this driver :-(
I'm using the sc16is750 on an imx6d platform i have tested it with a
vanilla kernel and RT patches applied.
I have our hardware hooked up to a PC using an ttl ftdi chip, both the
sc16is750 and the ftdi is setup:
$ stty -F /dev/tty[dev] 115200 raw -echo
From the PC I cat a large file:
$ cat /var/log/pacman.log > /dev/ttyUSB3
And on the imx I open and closes cat:
$ cat /dev/ttySC0
