STM CircleOS forum / relocating at 0x80001000 and no Systick interrupt

diegotrex · 2011-11-27 18:48:15

Hi to all in the community from Diego ,Milan,Italy,i'm a newbie ,and living 12 Km from ST factory does not change the fact.Forgive in advance my basic English and errors.

I'll try to simplify the question:

I did an example project on IAR EWB kickstart,blinking a LED, basing on Systick timer.
If i let the linker work with default settings everything works.

If i try relocate the code and the interrupt vector table, at debug start i have my program mapped in a way that the stack address is at 0x8001000 ,the reset handler is at 0x8001004 and so on.I verify that the contained address actually points where the interrupt routines are.
But when i run it the program moves along the code, but never enters in Systick Handler routine .Why?

Including a macrofile containing the following doesn't change the behavior.
execUserReset()
{
MSP = *(int*)0x08001000;
PC = *(int*)0x08001004;
}

Thanks for help ,or just for spending your time reading this topic.
Diego
