How enable сache without MMU in u-boot DM3730

Ilya Sklyarov

Hello All,

There was a need to enable cache in u-boot. During the connection cache found out that it is necessary to enable MMU. How to enable the cache without MMU and is it possible?

Thanks!

Hello Ilya,

If you are talking about the Cortex-A8, then to enable L2 cache, you must also enable MMU.
