Dear All,

I have encounered a problems with interrupts while running code from RAM...

Environment:

Keil uVision 3.55a and MDK 3.15b

I took an example from Examples\ST\STR71xLib\Tim\OCMP and changed it in the way to work in RAM.

What i see is that Timer 3 output compare function pin triggers but interrupt routine doesn't work (there are no port pins toggling)...

When i run it in debug mode (using the internal uVision debugger) all seems to be working...

Does anybody encounter with such problems before?

I would be very appreciated for your help.

P.S.Source code i'm experimenting with is attached for your consideration...

Thank you.

I have an STR710 interrupt example running from RAM and the porject setting is different than yours. you can check also the boot pin on your board. I attached my setting. Hope this helps you,

Cheers,

Chris.
