The dev kit power adapter is rather reliable, but in other cases of different power supplies the Xavier can be picky about regulation right at the instant of powering on. It sounds like your power adapter is not the one which comes with the dev kit, and so under the circumstances I do suspect it is a power supply issue (though not necessarily). Can we confirm this is a dev kit, and that the power supply is not the default dev kit supply?
Some typical cases where there might be a power delivery issue despite no hardware failure:
- Power supply itself does not regulate well during initial power spike requirements,
- Power cables are longer, introducing resistance (tiny amounts of resistance matter).
- Power cables are lower gauge (also introduces tiny amounts of resistance, and this matters).
- Power connector is slightly wrong in size. There are many connectors advertised as “5.5mm” outer diameter, but inner diameter may actually be either “2.5mm” or “2.2mm”. Some with the wrong inner diameter don’t have problems in most cases, but for supply of a Jetson, tiny resistances matter and the connector itself may be unreliable for a Jetson.
In many cases where resistance is a problem adding a high value capacitor (perhaps over
2000uF) right at the connector can help.
In cases of actual hardware failure the failure is almost always due to a failure on the carrier board, whereas the module normally does not fail.
