Re: RTDM assertion failed RTAI 4.0 and 5.1test

Hi,

HELLO , there is someone who uses Serial ports with RTAI 4/RTAI 5 ?

When I try to open my serial port with rt_dev_open, I have a call
trace and RTDM error msg :

[ 8008.399827] ------------[ cut here ]------------

But if I don't use Serial Port, I have no call trace and everything
works as expected !

Thx for your help.
