Effect of optimization levels while using freertos on cortex-R52

Hi everyone,

When I'm using FreeRTOS with cortex R52, in optimization level O0, it works fine. context swithing is also fine.

But when i use optimization level O3, there are so many issues and they are very random. My question is ..whether there is a problem with FreeRTOS in optimization level O3?

Any small suggestion will mean so much to me.

Thanks & Regards,

Jahnavi Guvvala.
