STR73X interrupts

I have over 100K ported and performing final testing but have discovered some problems with the EIC Interrupts.

Interrupts are occurring but it appears that some extra ones are also occurring. This is happing on both external interrupts and interrupts generated by the timers.

Any one else seen this?

Have any suggestion?

Anyone even using this derivation?

It seems like this group is not very proactive or the ST ARM's are not being used.

I'm using the Keil compiler.

Hi !

Did you ensure that you erase all necessary flags for that specific interrupt ?

e.g. Timer 0 has two flags.

one which informs you about the overflow (or capture, or ...)

one which informs you that the interrupt is (still) pending

clear both in the correct order and that shall work
