I used the origin system of 35.2.1,the system crashed when booting

[tianyi2]

Hi,
I downloaded the Tegra_Linux_Sample-Root-Filesystem_R35.2.1_aarch64.tbz2 and Jetson_Linux_R35.2.1_aarch64.tbz2.
Then I executed sudo ./apply_binaries.sh in directory Linux_for_Tegra.
Then, I run sudo ./flash.sh jetson-xavier-nx-devkit-emmc internal to burn Xavier NX.
Last, I boot the system,and after booting succussfully 4 times, the Xavier NX crashed.
The attachment is the crash log.

Hi,
Please try to flash the device through SDKManager and check if the issue is still observed.

That issue is not related to display. Should be related to ethernet. No solution yet.
