I am working on an NVIDIA AGX 32GB (Jetpack 4.6.1) for a project at the moment. We are connecting a switch with 2 cameras to the ethernet interface of the Jetson and while setting the MTU to 9000 it reboots. I saw that you were active in some discussions about this problem, such as in ‘High MTU causes Kernel Panic - #23 by k-hamada’. The Jetson supplier prepared the patch of the /boot/Image for us. After applying this patch on one Jetson, it kept on restarting with higher MTU. However after a week of developing other stuff (with MTU 1500), suddenly the MTU 9000 worked. On the second Jetson we again see that it restarts after applying the patch+MTU 9000 and we don’t have the time to wait multiple days, due to being in another country for the project.
We replaced both the /boot/Image and the /boot/Image.t19x files with a patched version which should allow this higher MTU.
Thank you for the fast reply. Does this reflashing cboot really require connecting an external (Ubuntu 18.0.4) device and running a flashing script? Our Jetson is integrated in a production closet, so I would want to avoid unmounting and opening it up. Is there a way to manually update this /boot/Image patch from CLI, without fixing the kernel in the long run?
