STM32F7 Caches

[cipher]

Really quick question
I was looking through ChibiOs code trying to learn and understand it more, and as i understood from forum posts both Instruction cache and data cache should be enabled by default, however i couldn't find where they are getting enabled in the code. SCB_EnableDCache and SCB_EnableDICache are declared in core_cm7.h but never being called anywhere
Any hints?

Hi,

GCC startup files do that internally, other compilers either do that in their runtime libraries or it is up to the application to enable it.

That's good that I've asked
I'm using IAR so I guess I should enable caches right in my main()

Just to confirm, in my case, both instruction and data caches were disabled, i checked the SCB registers, i put the appropriate calls in my main to enable them both
