hello.
I have a demojm board with a mcf51jm128 cpu. My OS is Win7 x64, and I'm using the latest version of CW.
The problem is clock configuration function, the CPU freezes on the following loops:
while(MCGSC_IREFST != 0U)
while(MCGSC_PLLST == 0U)
while(MCGSC_LOCK == 0U)
(MCUinit.c file)
If I comment these lines the CPU is working correctly.
How to solve that problem? If It's needed I can send you a clock configuration preset from CW (*.dev file).
Thanks.
Edit:
I upload preset screenshot and Processor Expert dev file.

Looks like your crystal oscillator doesn't start.
I'm using the default quartz on the DEMOJM Board.
Changing External oscillator to External crystal nothing change. The CPU is looping on the "/* Wait until external reference is stable */" loop.
IT WORKS ;-)
You must change the "external ref clock for peripherials" to enable state.
