Ping32: no green LED
Greeting,

I have two Ping32 units. One is working well; solid red LED with flashing green LED. I found another behaves differently. Only solid LED, no green LED. Pushing RST switch makes no effect. BUT-RST-!RST-!BUT sequence does nothing while the first one starts green/yellow LED alternative flashing. I'm afraid I mistakenly damaged one. How can I fix the symptom? The suspicious worked for a while at the very first power-on about 2-3 minutes but then its green LED flashing stopped.

RE: Ping32: no green LED
can you test the power supply ( 3,3V and 5V on the connector ) ?
Did you uploaded a program in the first one ?
