In my program, I set up the clk with PLL_setFreq CSL
function. This function works fine when the code is
loaded by emulator. 
But when I burned the code in I2C EEPROM and bootload
the code, PLL_setFreq fails. The PLL never locked and
the function waited indefinitly. I can ensure that the
code is loaded into DSP correctly.
Is there anything I ignored?
thx

Where and when do you set the PLL registers? What processor do you have?

If I recall correctly, you need to prepare your system for a PLL
register write. I mean that you can't do it anywhere/anytime in your
program (maybe this is obvious). Is it possible that the emulator does
this "PLL write preparation" automagically, whereas when you don't use
the emulator your system is not set up correctly for a PLL register
write?

I do it in main(), from my own asm-function which calls writeport().
I'm using 5501.

Hi
 Thanks for the reply. I am not yet running my code on C5510 directly. Currently i am coding
the different functional modules of my project on C5510 device simulator in CCStudio. I know
the hard part is yet to come but even in a simulator, the dsplib functions are behaving in a
weird manner. I am following all the instructions in dsplib documentation including #pragma
declarations for data structures and  boundary alignment in .cmd file. 
Thanks again
Asif
