Hi Hossein

thanks for he reply. No i didn't know about these slides .... I read them just know, unfortunately they are not talking

at all about C55xx (although a lot still aply and can be inferred) .... and they do not even touch (unless I didn't read well) to

using the .tcf and tconf manually ..

But i would say, I would have loved to have this training before starting the project :)

gds,

Jacques

Hi,
some more details: I realised that, the C55x there are 3 timers and so, as DSP/BIOS uses timer0, theyr added an additional property to the CLK object, which i used:
ios.CLK.TIMER1FUNC = prog.extern("timerHWIAsm");

then I had to write an simple assembler wrapper so i can use a "SEM_post" inside my handler (that's all it is doing).
So, no more errors, and indeed, the interrupts fires once as expected ... but does not fire again. Thta's probably to do with re-enabling it, or the like.
However, i noticed that, as soon as I used this TIMER1FUNC property .... then all my runtime is gone (this is an audio app), there there must be side effects sometwhere ...

Any ideas ?
Jacques

PS: Of course, my code is fully initialising the Timer1 registers ....
