Hi, I currently having a really hard time flashing JP4.6 or JP5.1.1 to a Xavier NX using the initrd script. A couple of times it worked for JP5.1.1 but its really flaky, have not been able to get it to work at all on JP4.6. I want to flash nvme, the diferent attempts: Worked a couple of times on…

For any one else having issues, a workaround that we found is to use a fresh install of ubuntu 18.04 or ubuntu 20.04. Overall it seems to have less issues on 18.04.

@linuxdev , seems its not enabled, doesnt do anything when I hit those keys. It does have ethernet will check the router logs to check if its online

Unfortunately the router doesnt report that there is a new connection, seems something is causing the network to not go up. Will verify once I get serial. The weird thing is that it happends with the custom rootfs with custom dtb/kernel and also with a fresh rootfs from the Tegra_Linux_Sample-Root-F…

It’s really not possible to tell what is wrong by just reading your flash command or host side log. If you ever saw every kinds of initrd flash issue reported on this forum, you would know the flash command won’t provide much info.

I’d agree that without the serial console log there isn’t much possible. One exception might be due to the fact that you are using an NVMe drive. You could put that drive on a second computer, and look at logs in “/var/log”. If the Linux kernel did not load, no logs will be there.

@WayneWWW , Hi I’m back with logs now. What I did: Flashed default JP5.1.1 on emmc using sdkmanager. Flashed default JP5.1.1 on nvme target using sdkmanager, got error, same …RTNETLINK answers: File exists, for a while and then timeout. Took nvme out to format and clear all partitions. Tried agai…

Is this test done on your board or nv devkit?

Its on this carrier, I dont have a devkit readily available but, the carrier is able to start and work normally with default JP, without their bsp, at least the ethernet, usb flash port and serial port work fine. Also nvme gets properly detected, and on the first two attemps was able to get flashed …

Does usb device mode launch and able to to ssh between your host and jetson?

Do you mean the 192.168.55.1 via usb? On this carrier I cant, but on the first carrier I can.

Just to be sure, does the l4t_initrd_flash script does fuse flashing? 'cause its weird that on the two boards I was able to flash nvme two times, and after that I’m not able to do it following the exact process.
