Dear NXP team,
I use S32G-VNP-EVB and "Linux s32g274aevb aarch64 GNU/Linux".
I have written a little program in attachment. There are always unexpected delay over 200ms.
It is just a for-loop, which will be called every 10ms using thread.
for(int j = 0; j < 150000; j++);
The runtime of this for-loop takes about 1ms. Sometimes this for-loop was called after 200ms.
Best Regards
Linux is a multitasking environment. There are always some interrupts and/or
active tasks in the schedule. If your task/process experiences delays, the
system must be busy with something else. Run any available Linux profiling
tool to find where CPU spends time.
Best Regards,
Platon
