Hi! So, I’m currently using an NVIDIA Jetson TX1 in a mobile robotics application. However, our Jetson has, as far as we can tell, stopped working. When we plug it in to the provided 19VDC power (verified correct with a multimeter), the red power LED (CVM Powered) next to the fan header lights up. However, the board does not boot when any of the buttons are pressed. None of the other lights (PCIE/SATA Powered, SOC, PWR) don’t flash nor turn on, the fans don’t spin, no monitor output, no USB devices can be seen from a host computer after the recovery mode key sequence, etc. Additionally, the GPIO pins (J21) as well as the pins of the USB 3 port are not powered. We’ve tried reseating the compute module and trying multiple different power supplies, to no avail. None of the components look damaged nor do any of the capacitors. The board wasn’t subject to any high vibration or shock environments (nothing past picking it up and carrying it around), nor was used with any power supply of a higher voltage than the provided 19VDC. Using a voltmeter to measure between VDD_IN and GND on the bare CVM connector on the carrier board yields 1.95 VDC. This is much below the recommended minimum of 5.5v (assuming I’m reading the datasheet correctly), leading me to believe the culprit lies within the development board’s voltage regulators.
Are there any troubleshooting steps we should take that we haven’t described, or is our Jetson completely toast?
Thanks for any help!
