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

    HUH???    The CM3 has no cache.  Maybe there is some on-chip (but off-core) high-speed RAM you're talking about?

    Could you please give more details (be specific!) so we can try to help - thanks.
