Hello,

Can you confirm that L1 & L2 caches are enabled on all A72 and A53 cores when running Yocto Linux (latest from branch “LinuxImage3.0”.

Thanks,

Edouard

Certainly, why exactly are you asking this?

hello @marcel.tx,

I’m benchmarking the chip, just want to make sure I’m getting the best performance out of it.

Perfect thanks for the feedback. As Marcel said the caches are enabled by default.
