Flash Failure | NFS error

Hi Team,

We are using a custom board based on the Jetson Orin NX module, running JetPack 6.2, which includes Jetson Linux 36.4.3 (Kernel 5.15) and an Ubuntu 22.04 root file system.
Some time we are facing flashing error and showing

Flash failure
Either the device cannot mount the NFS server on the host or a flash command has failed. Check your network setting (VPN, firewall,…) to make sure the device can mount NFS server. Debug log saved to /tmp/tmp.neJqOrObfe. You can access the target’s terminal through “sshpass -p root ssh root@fc00:1:1:0::2”
Cleaning up..

What is the reason for this

Hi,

Please try to disable the firewall and flash again.

Thanks

Hi David,
checked the ufw status
sudo ufw status
status: inactive
it is inactive

Hi,

We need you provide the serial console log for us to review.

Thanks

Hi david,
understood, but we are accessing the device through SSH we didn’t have UART log. May i know what are the possible reason for this error

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

sudo ufw allow from fc00:1:1::/48 to any port 22 proto tcp
sudo ufw reload
