Hi,
A collaborator of mine recently reported a beeping power supply and flashing CR5 lights (CR6 does not come on). The dev board does not boot and I’m not sure what happened. Does anyone of the forum have any helpful leads? Any help is appreciated.
Hi, CR5 on indicates that the 19V input power supply is normal. CR6 off might indicate the 5V of carrier board is off too. Please measure the power on sequence first as OEM DG said, to find out which signal is wrong.
