Can't get past ubuntu configuration Auvidea J120 Jetson TX2

Hi, I’m having issues getting the OS up and running on my TX2 using the Auvidea J120 carrier board. I follow the steps to download the image using Nvidia sdk manager and Jetpack 4.6.3 and then copy in the J120 firmware files into the Linux for Tegra folder. I do apply binaries and run the flash script with mmcblk0p1. Everything flashes great and boots up to the license agreement and user config etc. but after it begins the process of configuring everything the screen goes blank. Is there anyone who has had similar issues that can point me in the right direction as to why its not configuring properly?

It sounds like a video issue, which is fairly common. Do you have serial console access? This should work regardless of the monitor. If you can log in via serial console you can gather some information. Before doing so, is your monitor purely HDMI? Are there adapters involved? Is there anything unusual about the monitor?

Incidentally, firmware is often an issue (the device tree). However, you mentioned that you copied J120 firmware in, and so probably this is correct. That leads back to video configuration again (firmware can greatly influence monitor function; serial console login would make it possible to confirm).

@linuxdev Thanks for the help! My monitor is purely HDMI and I use a HDMI to HDMI mini cord to plug from J120 board into monitor. It’s a really standard Samsung monitor nothing unusual.

I managed to get some serial output after going through the configuration steps. The last step I configure before things seem to crash is setting the Nvpmodel mode to MAXP_CORE_ARM (default). Then it has some progress bars inidicating setting things up and then things pretty much go blank after some brief bootup output.

Here is the result of the serial log:
[ 3050.614048] device-mapper: table: 253:0: thin-pool: unknown target type
[ 3050.624681] device-mapper: ioctl: error adding target to table
[ 3053.007876] device-mapper: table: 253:0: thin-pool: unknown target type
[ 3053.018154] device-mapper: ioctl: error adding target to table
[ 3053.405657] CPU1: shutdown
[ 3053.477495] CPU2: shutdown

Are you able to log in then via serial console, and it fails upon setting nvpmodel? Probably the nvpmodel should be a different forum thread, but what command did you use? If you don’t change models, does video work?

If you can log in via either serial console, or via ssh, can you get a copy of “/var/log/Xorg.0.log”? If serial console, then you can tell it to log the entire boot before you start boot (the early content is good; a full log is much better than a short excerpt), and then “cat /var/log/Xorg.0.log”. Serial console programs have logging functions.

If you use ssh, then the scp command can copy that file from Jetson to host PC. Then attach the log file.

Also, since there is a device mapper involved, are you using purely eMMC, or is there an external device involved?
