Jetson Nano since serial number > 1423XXXX not working correctly anymore

Robotics & Edge Computing Jetson & Embedded Systems Jetson Nano

We got a new batch of Jetsons arrived which do not work with our Images anymore.

1423XXXXX are still working
1424XXXXX are not working anymore.

The jetson boots, but the whole isp / vi unit cannot be correctly initialized.

I am hoping you can direct me in the right direction on how to fix this issue, since there are not many jetsons with serial number 1423XX left for our production to keep producing our systems.

Can it happen that differences between serial numbers are in hardware? Do we need new device tree for newer serial numbers or what is happening?

Here is the dmesg from the boot:

please check if you are affected by the PCN.

If it is, apply the overlay file from this website.

Hi, thanks for the fast response!
It seems to be this will be the case. How can I check if I am affected from PCN to be sure?

We are currently using Jetpack 4.5 still. Can I backport the overlay to this version or do you see any problems with that?

The Jetson Nano overlay is basically open source. So you could apply it back to old BSP.

You could try it first and if it is really related to PCN, you board would be able to flash after applying patch.

The changes were very easy and I could just apply the patch without issues! Now Jetsons are working normal again! Thanks for the fast help!
