Hello @S_katikala
I hope you are doing well.
NXP has a Real-Time Edge Software. Real-time edge software enables real-time capabilities via support for Preempt-RT Linux® for low latency applications, baremetal framework and support for real-time operating system (RTOS) on the Arm® Cortex®-A or Cortex®-M cores.
But unfortunately the i.MX8QXP is not supported for this OS.
Here are listed the supported devices:

There is listed the i.MXx Family, but it is only supported the i.MX8DXL.
Best regards,
Salas.
