Cortex M3 Cache disable

Note: This was originally posted on 23rd August 2010 at http://forums.arm.com

Hi everybody,

I have here an STM32F103ZE with an Cortex M3 core and I need to disable the cache. But unfortunatly I dont find any information about it. If I understood it right, I have to use the MPU - registers to disable the cache but i dont know which.
Hope you can help me!

Kind regards
Mathias

There is no cache in the Cortex-M3 core itself, although a particular ASIC may include one outside of the device through a memory-mapped interface. It is typical for the core to be directly connected to an on-device SRAM.

What are you actually trying to achieve?
