I’m using a T2080 RDB with linux version 4.1.8-rt8 with following kernel options
Processor Support -> CPU selection -> (X) Freescale e6500
Kernel options ---> Preemption Model (Fully Preemptible Kernel (RT)) ---> (X) Fully Preemptible Kernel (RT)
U-Boot SDK 1.7
QorIQ SDK (FSL Reference Distro) 2.0
Kernel config (below as attachment)
I tested the idle(!) system with the cyclictest v1.00 via SSH and had some runaways > 30 μs like you can see in the picture below.
All power saving options like CPU Idle or Dynamic Frequence Skaling(DFS) were disabled of course.
Do you have any ideas guys?
