Question: What should you check if the oscillator is not running on the FX2™/FX2LP™ board?
Answer: You should check the pin connections and the oscillator characteristics to ensure they comply with the EZ-USB® FX2LP™ USB Microcontroller High-Speed USB Peripheral Controller datasheet. For example, the RESERVED pin must be connected to GND, as specified in the datasheet Pin Descriptions. Not connecting the RESERVED pin to GND puts the chip in a test mode which can cause the observed behavior.
