Cache behaviour on AT91SAM9260

Fri Jul 24, 2015 9:25 am

Hello everyone,
I am using AT91SAM9260-EK. I am witnessing different cache enablement on different boards. At startup, on one board, MMU=On, ICache=On, DCache=On.
On other board, MMU=Off, ICache=On, DCache=Off.

I want to know how these caches are enabled at startup and can we overwrite this behavior?

Clarify what "startup" means, and how you are obtaining this information.
