We were using our Jetson as a main PC for an ROV, and is inside an closed enclosure with other electrical parts. The temperature inside the enclosure was around 40 degrees celsius, we did not see the jetson’s temperature, but when felt after (it shutdown), the jetson was very hot.
Below is the output when reading the serial debug from the jetson 's UART.
Nothing shows up after the last line. We are not sure if it is the jetson itself or maybe other potential problems like its storage. [Jetson Xavier NX running Ubuntu 20.04 on an SSD]
Yes, we were thinking about reflashing the board if we can’t find a better solution. Thankfully we can still access the data using an ssd enclosure and backing that up. Is there any resources I can read to know more about the error codes the bootloader is outputting, might be helpful in the future, thank you so much for the input.
If i remember correctly, it’s a reComputer Xavier NX from Seeed Studio. As for the jetpack version, I can’t recall what the specific version is, but I remember It was one of the first ones that supported Ubuntu 20.04 so it must be the early version 5s . I’m sorry but I don’t have the log when it shutdown at that time, and to be clear, the mentioned high temperature was only at the time of incident. The board now is just stuck at boot at idle temp without the fan spinning at all. For the power we were using a 4S battery boosted using a boost converter to 19V (with a DC jack).
Also, this might be quite important to tell that at that time we were trying out the 20W mode, instead of the normal 10W mode (which we have used for the longest time). During using and testing outside of the closed enclosure it was working fine. We tought maybe if it got too hot inside, it’ll just throttle hard, we didn’t really see that during testing outside the enclosure. But after using it in trials (inside the enclosure) for a few minutes, it shut down as I’ve said in the beginning. So we just assumed that after the incident maybe the harsh temps inside the enclosure was what made it stop working.
To add, we also have the Nvidia Jetson Nano Dev Board at our inventory, which we have attempted to swap the Jetson Xavier NX module into the Nvidia Jetson Nano Devboard, yet the result was the same, it did not successfully boot up. We have also determined that the custom Jetson NX carrier board was not the issue, as we have attempted to insert the Jetson Nano module into the custom NX board, and it boots successfully.
