Dear Sebastian, No problem.
I found that there is difference for accessing GT between Cortex-A7(i.MX7D) and Cortex-A9(i.MX6Q) by ARM technical manual. Therefore, arm-a9mpcore-clock-config.c should be not used for Cortex-A7 based SoC. If I have update in my side regarding RTEMS testing on PICO-PI-IMX7, I will let you know that. At this time, I am focusing i.MX6Q regarding SMP and USB Host, too. On referencing, I was successful to boot SMP kernel without u-boot on i.MX6Q. but, there is still problem for booting SMP kernel with u-boot. I guess that current problem is related with u-boot.
