It was good at the beginning, but the problem appeared after a period of use.

hello 1316886298,

may I know which JetPack release it is.
could you please share the details about what’s the software modification you’d done?
thanks

Jetson NX Developer Kit SD Card Image - JP 4.4 DP. The software did not make any changes.

hello 1316886298,

JetPack-4.4 DP is Developer Preview release,
please access JetPack SDK for JetPack-4.4 / l4t-r32.4.3, which is the latest production release.
thanks

Jetpack SDK for jetpack-4.4 / l4t-r32.4.3 also cannot be started. Whether the Jetson NX developer kit will fail to start due to sudden power failure. Through repeated power-on and power-off test, it was found that one board failed to start.

hello 1316886298,

according to https://developer.nvidia.com/embedded/jetson-xavier-nx-devkit, are you working with 19V power supply?

There is no update from you for a period, assuming this is not an issue any more.
Hence we are closing this topic. If need further support, please open a new one.
Thanks

Is this still an issue to support? Any result can be shared?

I have started to experience this issue also.

This same block of text keeps spitting out nonstop from the console port. I’m using the production version of the NX on a custom carrier board. I have verified that it’s the NX itself and not the boards. The NX modules that work function without issue on all of the carrier boards and power supplies that I have tested, and the NX modules that present the issue produce the same behaviour and output on all of the same carrier boards and power supplies.

Reflashing the NX modules does not help, it just does the same thing regardless.

Hi cbstryker,

Please help to open a new topic for your issue. Thanks

Actually, I solved the issue. I’ll just leave it here instead of opening a new (and solved) issue.

It seems this output occurs when the boot partition (or another) gets corrupted. I use a standard image that I flash to Jetson boards to clone our application. Cloning the image to the board again did not solve the problem.

What I did to solve it was to reflash the board through the Nvidia SDK Manager. My guess is that it flashed all of the partitions fresh, thus eliminating the problem. From there I could flash my own image and everything works.

Note that flashing signs the content prior to the flash. A signed partition on one Jetson will probably fail on another even if the non-signature part is correct. If you are interested in the topic, here are some URLs:

Although it has been solved, why is there such a problem. We have more than 20 sets with this problem. I did to solve it also was to reflash the board through the NVIDIA SDK manager.At present, there are no problems with the repaired ones, but we dare not use new ones.
