Hi,
From https://developer.arm.com/Processors/Cortex-R52, the CoreMark performance score for Cortex-R52 is 4.3 CoreMark/MHz.
Would you mind sharing the compiler version and the whole compiler options (prefer the whole project), I'd like to reproduce the result.
Thanks.

I wonder if they have a "coreMark" detection inbuild ?!
Thanks for your answer. In my case, TCM is also used.
I confirmed with the guys in ARM via email.
GCC/ARM: Cortex-R52 is 3.7 CoreMark/MHz.
IAR 8.5 : Cortex-R52 is 4.3 CoreMark/MHz.
Wow, that's quiet a difference. I would guess ARM uses ARM v6 (Clang) compiler.
Also they likely use "tricks" like TCM.
I got 3.72 CoreMark/MHz with gcc-9.2-arm32-none-eabi compiler. I would like to know what compiler is used by ARM and what are the compiler options.
What values do you get with your favorite compiler? Better or worse?
