This would explain why this bit has to be set accordingly telling the core to use the system bus and access the SRAM. I would like to have the option of relocating my vector table to RAM at runtime in a library ie if the code doesnt need to do this it doesnt and the RAM isnt allocated or is eliminated by section garbage collection during link The actual relcation seems simple enough but Im having trouble figuring out.

The Vector Table defines the entry addresses of the processor exceptions and the device specific interrupts. The ARM core up on boot up loads the stack pointer with the value stored at offset 0. Cereb Cortex 2516181628. As discussed earlier the ARM Cortex M series of MCUs typically carters to lower end application with the core running between a few MHz to a maximum 150MHz. According to the Cortex-M3 tech ref manual the VTOR is defined as. The Execution of the current task is suspended.
