Can't get past login on Jetson TX1

kmacprof · June 23, 2016, 12:47pm

I am trying to get going with my new Jetson TX1 running without success. I tried connecting it to my ViewSonic VG2228wm-LED but did not get a signal. Then I tried an Adafruit 7" 800x480 HDMI Backpack + AR1100 Touch Controller and it did begin to boot. But after entering the login, it executed a few commands and then restarts. Can’t get past the login to a command line.

I just retried with my ViewSonic monitor and I now have a signal, but am having the same problem of a reboot every time I enter the correct login information.

An interesting development: the only reason the ViewSonic works is if I first connect the 7" display, disconnect, and then connect to the ViewSonic. If I then reset the TX1, the ViewSonic will not display. At first it appears to get a signal since the blue light turns on in the front, but then the blue light turns yellow indicating no signal. The blue/yellow cycle continues indefinitely without displaying anything. But if I then reconnect to the 7" it shows fine, and will again if connected to the ViewSonic. Very odd…

The best way to see what’s going on is generally a serial console (the more you develop on a Jetson, the more useful this becomes). See:
[url]http://elinux.org/Jetson/TX1_Serial_Console[/url]

Note that when a Jetson first arrives, the operating system is purely Ubuntu. Running the installer completes the hardware-accelerated nVidia-specific file install, and may improve monitor function. The script is at “/home/ubuntu/NVIDIA-INSTALLER/installer.sh”, and is run with “cd ~/NVIDIA-INSTALLER ; sudo ./installer.sh”. This is of course a problem if you need the video to work to do this, and the video won’t work until you do this. Typically ssh or serial console is required in that case (these methods avoid having to use the graphical desktop). Flashing the Jetson will also complete the nVidia-specific file install.

I am having two problems, one is with the display and one with rebooting. I assume the serial console is an effort to fix the display problem until the full install is complete. I do have a work-around to get the display working, but continue to have the problem of the Jetson rebooting immediately after login. I assume using a serial console would not fix this problem, right? I can’t get to a command line to run the script you mention. Will running the serial console fix the login issue?

Also, what do you mean by “flashing” the Jetson?

The serial console is essentially a terminal which works even without graphics or network support. As a result, this also means that as the system crashes (or in your case reboots) you will be able to see messages as to the cause. Serial console implies that if anything from the graphical environment causes the reboot, this can be avoided while figuring out what is going on. Serial console is always logged in…there is no issue with login causing reboot if login is from serial console…you can run the final install script via serial console under almost any failure condition, so this is indeed one of several ways to finish that install (and probably the simplest). Think of it as the Jetson dealing only with characters sent to it, and any keyboard or display interface running on a separate machine which offloads those functions.

A JTX1 arrives with L4T R23.1. Flash completely installs a new version of L4T. R23.2 fixes many bugs, R24.1 is available for some new 64-bit functionality. You will probably want to be able to flash R23.2 even if you do not develop your own software on Jetson. This is done by putting the Jetson in recovery mode (hold down recovery button and either turn the system on or reset) over the micro-USB cable…the desktop Linux host runs the flash software (“driver package” plus sample rootfs…or the bundled installer, JetPack).

Ok, I see. I have successfully attached a serial console and started the TX1 with Ethernet connected. It runs through a mass of output during boot up, but always ends with an error of a non-existent directory. A portion of the output appears below. Suggestions?
