VDK and idle state

Hi,

I use VDK in my application with blackfin processor 537.

 

I was thinking of putting the core in idle state that may save some power, when there is not much to do for DSP. I tried this with simple code as follows.

 

CLI R0 ;

IDLE ;

STI R0 ;

 

And failed. With crash!

 

I could not think of a best place to do this other than VDK idle thread. Taking care that 'wakeup' is enabled for all the concerned peropherals.

 

Has anybody tried it already ?
