Hi 

I have used the  PREEMPT-RT patch for the fsl kernel 4.1.15. But the problem of USB failure appears when the power is turned on.When this problem occurs, all USB is not available.My test results are as follows:

rt18+0001 : turn on and turn off the machine 2429 times, this issue will happen

rt18+0001+0002 : turn on and turn off the machine 24 times, this issue will happen

rt18+0001+0003 : turn on and turn off the machine 899 times, this issue will happen

rt18+0001+0002+0003 : turn on and turn off the machine 27 times, this issue will happen

Hi

one can try with official nxp bsps described on

i.MX Software|NXP 

nxp does not support PREEMPT-RT  in its bsps and issues with PREEMPT-RT patch can be posted on

realtime:communication:mailinglists [Linux Foundation Wiki] 

Best regards
