Hi,Nvidia
I have tried more than a dozen times and have been reporting the following error
19:38:51.777 - Error: Flash failure.
19:38:51.780 - Error: 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.nkhP1BYqmn. You can access the target's terminal through "sshpass -p root ssh root@fc00:1:1:0::2"
19:38:51.782 - Debug: The last 5 lines of the debug log are:

Cleaning up...
1.I’m using my own motherboard instead of the official one, but I can sometimes flash it successfully on a Lenovo host, so the motherboard should be fine.
2.I’m not using a virtual machine — I’m running it on a native Ubuntu 20.04 host.

I’ve already replaced it with a high-speed USB data cable, but the issue still occurs.
I’ll post the complete log once I finish my other tasks and also try the thread you mentioned.
Thanks a lot for your help and suggestions!
Hi @nico.morua
Sorry for replying to you so late. I’ve resolved the issue.
First, it must have a cooling fan added;
second, it needs to be connected via the serial port.
The second factor has the most direct impact — without the serial port connected, it will keep failing. This is likely related to the power supply design on the backplane I created.
