When I made a remote desktop connection to it, I found that I could not establish a network connection with it, which had been fine until then. After many attempts, it was found that the network configuration option in system Settings had disappeared, and eth0 could not be found when the terminal typed “ifconfig”
Is this caused by an Ethernet driver problem or external damage to the device?Thank you. Please help me
Not an answer, but some details might be useful to know: During flash the Jetson must be in recovery mode, and no network is required (it does use USB). Once flash completes the Jetson will automatically reboot to Linux for first account setup. Once this is booted networking is indeed used for various extra packages to be installed. One network which is possible is a virtual ethernet over USB, which is available as address 192.168.55.1 if it works. If there is no network, then flash itself will still complete, but options like CUDA will be missing.
If there is an issue with network devices not showing up, then you need a serial console boot log since it shows what goes on prior to Linux itself loading.
