Code in tightly coupled memory

hi Jens,

In your case, was disabling interrupts for TCM code necessary for the correct execution of code itself or only for performance?

In my case I'd allow interrupts since I need to speed up the "average" function execution time and I don't mind if it is sometimes interrupted; think that this function is almost always running, so it DOES need to be interrupted.

Can this be the reason why the simple function works while the complete one doesn't?

Same question above about placing variables in TCM.

I finally agree with your last remark: I'd expect performance increase not for the TCM itself but because sdram is now intensively accessed by other masters through dma.
