I cannot connect my Jetson Xavier NX to a display using either tty or HDMI. If I connect with the Micro USB I can see it listed in system_profiler (OSX) or with lsusb but I can’t actually connect to the device. I have a flashed SD card.
Actually I think the issue is that it won’t boot. If I check on lsusb it looks like It is in recovery mode as I get an ID 0955:7e19 NVIDIA Corp. APX. Is there any way to force it into setup mode?
If the system is fully booted, then the micro-USB can emulate certain devices, e.g., a virtual network adapter or a virtual mass storage device. The presence of the 0955:7e19 could indicate recovery mode, but it can also indicate a fully booted system due to the custom emulated devices.
If you monitor your PC via command “
dmesg --follow”, and then connect the powered up NX’s micro-USB, what do you see in the dmesg log? Once connected, from the host PC side, does “
ping 192.168.55.1” succeed?
FYI, forcing recovery mode is done by shorting the recovery mode pins (one is the actual pin, the other is just ground) while either powering up or resetting power.
thanks for getting back
'dmesg -follow` returns with

This might be in recovery mode. When connected what do you see from “lsblk -f”? I am curious if a new block device shows up.

i have a 500GB samsung SSD attached and a 128GB SD Card. I don’t think the SD card is being read.
lsblk -f is from the host PC with the Jetson’s micro-B USB cable connected, then indeed the Jetson’s normal sample mass storage device emulation is not showing up. This would be consistent with either being in recovery mode, or optionally a failed boot.
…for this above, are you saying these also do not show up on the host PC with
lsblk -f? I too did not see these on your
lsblk -f, and if the PC cannot see these devices, then any copy to the devices would also fail even if the devices are otherwise functional. Can you give more details about what you see from the host PC for those devices?
