STM CircleOS forum / Interrupts not working

mac_droz · 2009-06-03 10:29:53

Hi all,

I am writing my first non-CircleOS application and I hit the wall.

My Systick interrupt is not working. The program is executed properly until the interrupt occurs and then the PC goes to 0 and program hangs. It seems like there is no vector table initiated. My question is: how to do it? I have stm32f10x_it.c added to my project but it seems that it does not produce the vector table.

Is there any proper documentation on how GNU compiler work? Their website seems a mess. Any proper pdf?

You don't have SysTickHandler() defined, so linker provided the NULL one?

Can't do more than speculate with info you wrote :-P Code always helps.

This is not related to the GNU compiler... I suggest you look at the ST projects in the STM32 library. The latest version is available from the ST web site. A former version is installed with RIDE+RKit-ARM, so you should have it on your PC in :
\Program Files\Raisonance\Ride\lib\ARM\STM32F10x_LIB
