Jetson nano board setup failed and stuck with nvidia logo

Hi, I have Jetson Nano 4gb and flashed Jetpack 4.6.3 to SD Card using sdk manager. I’m using 5V/4A power supply. Plus I’m using Nomachine and MobaXterm for headless mode.
However it stucks on NVIDIA logo but can connect via ssh.
Here is my boot log.

You mean you can connect to the device via SSH, but how do you know the IP address without at least getting into the desktop, or you mean serial connection? Does connecting the device to a real monitor make any difference?

If the system has some problem with display signal, usually the monitor will turn black after the UEFI logo, but not get stuck with it.

No, I didn’t use a serial connection. At first, Jetson’s gui worked fine. (I used a real monitor)

Therefore, I could know the IP address. However, at some point, gui suddenly didn’t start. And when connected to a real monitor, the nvidia logo is printed at a low resolution (probably 1024x800) rather than a monitor resolution. (like the image I posted)

I’ve followed this post to solve the low resolution (640x480) problem with NoMachine.

Would adding a fake screen inside xorg have affected this issue?

Hi, usually adding a fake screen should be a feasible workaround, but there seems to be something wrong with the tegra-i2c error.
Can you put the entire dmesg here?

7

Seems similar to these two posts, give them a try and see it they help

Hi, this is the whole dmesg log.
dmesg_291.txt (55.4 KB)

Thanks for your help.

Hi, do you still encounter the i2c error if you connect the device to a real monitor?

10

It’s now working. Thanks a lot!

But I have another problem for now. I was originally using Python 3.7, but I changed it to Python 3.6 to install Pytorch. After that, when I run jtop, the following message appears.

Traceback (most recent call last):
File “/usr/local/bin/jtop”, line 7, in
from jtop.main import main
ModuleNotFoundError: No module named ‘jtop’

Please help.

please file a new topic if it is not related to the original one.
