How to relocate the Cortex-M3 Vector Table

Note: This was originally posted on 9th November 2011 at http://forums.arm.com

Hello,
I am Davide Masi and I work on Fujitsu based on ARM Cortex M3.

How do I relocate the interrupt vector table from address 0x0000 to a different address, for examples in RAM?
Where can I find examples or AN about the problem?

Thanks

Hi David,
Welcome to the forum.

Maybe you can use the Vector Table Offset Register (VTOR) to do this.

Examples can be found in various forums by searching for "SCB->VTOR".
One example is on Keil forum: http://www.keil.com/forum/17484/
