Hi everyone, I am facing a critical power issue with my Jetson Orin Nano DevKit. The system fails to boot and shuts down completely within 10 seconds of power-on. Most importantly, I am unable to get any serial console output from the debug port, making it difficult to diagnose the root cause. I am seeking advice to determine if this is a recoverable firmware issue or a hardware failure.
Description of the issue: My Jetson Orin Nano powers off automatically about 10 seconds after connecting the power.
The Power LED turns on initially.
The fan starts spinning.
After ~10 seconds, the fan stops and the LED turns off completely.
No display output on the monitor.
Debugging attempted:
UART Debug Log: I monitored the J14 (Button Header) Pins 4(TXD) and 7(GND) using an Arduino bridge at 115200 baud. No data/text was received at all.
Minimum Configuration: I removed the NVMe SSD and SD card, but the same issue persists.
SOM Re-seating: I have tried re-seating the SOM module to ensure a proper connection.
Power Supply: I am using a 19V 3.42A power supply.
Environment:
Module: Jetson Orin Nano Developer Kit
JetPack Version: JetPack 6.2
Question: Since there is no UART log output even on MB1 stage, is this likely a hardware failure of the PMIC or the SOM itself? Are there any other hardware-level tests I can perform before requesting an RMA?
Can your devkit boot as expected bofore?
If so, what you have done to cause the current issue?
Could you enter into force recovery state and it can be recognized by the host?
If so, please connect it to your host and use SDK manager to reflash it.
Hi, thank you for the response. Here is the information you requested:
Can your devkit boot as expected before? Yes, the devkit was working perfectly before. I had previously booted it and successfully installed several programs, including Anaconda and Python.
What you have done to cause the current issue? I haven’t made any major hardware changes. After using it for a while, I had to leave it unused for about 2–3 months due to my schedule. When I recently tried to power it on again, the issue started. Before the hiatus, the last thing I did was install software like Anaconda and Python, though I don’t remember the exact details beyond that.
Could you enter into force recovery state and it can be recognized by the host? I have already attempted to enter Force Recovery Mode, but it was not recognized by my host PC (Windows). Here are the specific steps I took to debug the device:
Force Recovery Mode: I followed the manual by shorting Pins 9 and 10 on the J14 (Button Header) during power-on, but no “NVIDIA Corp” or “APX” device appeared in the Windows Device Manager.
UART Debug Log: I also tried to capture the boot logs via the UART2 (DEBUG) pins on the J14 header (Pins 4 for TXD and 7 for GND) using an Arduino as a serial bridge at 115200 baud.
Result: No data or text was received at all. The serial console remained completely blank, and the device automatically shuts down after about 10 seconds of the fan spinning.
