Finding L4T and revision versions

Hello all,

Just got my TX1 and I was checking about the availability of INA monitors on board of my Jetson TX1 (not the carrier board). I received the board 2 weeks ago and hoping it has the latest revision of 300. But, I could not find and confirm it. I have upgraded to the latest jetpack as well.

I am following the information in this link. But it does not seem to give the L4T version nor the revision. Can anybody help please.

ubuntu@tegra-ubuntu:~$ head -1 /etc/nv_tegra_release
# R24 (release), REVISION: 2.1, GCID: 7791156, BOARD: t210ref, EABI: aarch64, DATE: Thu Sep 29 00:59:21 UTC 2016

ubuntu@tegra-ubuntu:~$ sudo i2cdump -y -r 0x14-0x26 2 0x50 b
     0  1  2  3  4  5  6  7  8  9  a  b  c  d  e  f    0123456789abcdef
10:             36 39 39 2d 38 32 31 38 30 2d 31 30        699-82180-10
20: 30 30 2d 31 30 30 20                               00-100

Thank a lot for your time

Translated it says:

L4T 24.2.1

Module SKU:


For L4T, the major release number is 24 (R24), the revision is 2.1 which leads to L4T 24.2.1

The module number is simply a concatenation of the two lines

The module number is simply a concatenation of the two lines

So, in this case it is 699-82180-1000-100 right?

According to the link I quoted "

The feature to enable use of INA monitors was added starting with revision 300 of Jetson TX1. For example, SKU 699-82180-1000-300 (note the "-300") has the feature.


Still, there is no -300 in there. How would I determine if it has this feature or not?

To consolidate your posts and add to the continuity of forum threads, please continue your questions in:

That post states that the feature is in module -300, the module info above appears to indicate that you have -100.

This thread asks how to read the version number and module number.
