Unable to Enter Debug Mode via Cyclone Rev B If Target is 1.8V

Hello Everyone,

 

I'm having a really strange issue between the micro 9S08QE32 and Cyclone Pro Rev B. If the micro is running at 3.3V, the Cyclone is able to enter debug mode without any problem. However, when the micro voltage is at 1.8V (which is within the micro specification) the Cyclone refuses  to enter debug mode. I believe the Cyclone will work with 1.6V to  5V.  Is there any setting on the cyclone i can change to make it works ?

 

Environment:  CodeWarrior for MCU version: 10.5

 

Thanks,

Vu
