PLL power configuration using System Services on BF561 hangs

Hi all,


1. I'm having trouble to initialize the power service (adi_pwr_...) on the BF561 (on the EZ-Kit Lite), it even happens when I compile and run an example code coming with the VDSP. It is stuck on some instruction inside the _adi_pwr_program_pll() function in adi_pwr_asm.asm. Only by pausing program runtime (shift+F5) and resuming several times I am able to get out of this function. Still the program does not proceed normally. I am not able to understand why is it so, and why sometimes the same code runs ok. I have never had such problem on the BF548. Am I missing something?


2. I am also unable to get any interrupts on the BF561 (timer interrupts, for example) - again, using timer service. The same sequence on code does generate interrupts correctly on the BF548, though.


I'm using VDSP++ 5.0 and debugging through HPUSB-ICE.


I'm putting a very simple code I have made - I am willing to receive interrupt callbacks.

On  BF548, the callbacks are generated normally, while on BF561 they are not.


I'll appriciate any help or tips.
