Hi, Rahul!

What messages does debugger send after calling SysCtrlInit();?

Igor

Thanks Igor,

After that 'Step over' and 'Step into' key are UNhighlighted. But can't figure out where the control has gone!!. Please refer the bellow image.

Hi!

Perhaps I don't understand something at your problem...Did you try go through your code with use of "Step over" button only?

Sorry if my questions sound silly but did you:

a) try to stop the code and press step after that?

b) disable code optimalization

Yeah Maciej, I placed Break point before calling SysCtrlInit(); function and after that also. It will stop at first break point and then if I press step over or resume it will not show the code execution pointer, I dont know where the control pointer(Code line pointer) has gone!!. Surprisingly I see Emulator is running!.

Thanks,

Rahul

Controller is not getting out of this statement "while(!SysCtrlRegs.PLL2STS.bit.PLL2LOCKS); " which is in SysCtrlInit function.

Indicating that SyPLL2 is not yet locked!!
