Auvidea J-120 + Jetson TX2 issue: Fixed in JetPack 3.2? about redtail HOT 5 CLOSED

To your last question: the current directory is this directory.
However, we now recommend applying latest patch from Auvidea website instead.

As for JetPack 3.2: we haven't tested it yet so I cannot say whether the issue has been fixed in that particular version of dev preview release.

• the patches should be cumulative, so apply only the latest one (1.5)
• as I understand, you need to execute both steps according to the instructions. However, if that does not work, I suggest opening an issue on Auvidea support page.
  Note about our patch: it fixes USB 2.0 but does not enable USB 3.0 but if you don't use USB 3.0 you can still try it as it seems to be a bit easier to apply.
• either way should be fine. The patch fixes a bunch of issues specific to J-120 and should not affect how Jetson works on dev kit board.

Also, could you clarify how to patch the Jetson exactly? I am confused about the following statement:

Copy .dtb files in the current directory to the following directories:

If under the current dir you mean the folder where the JetPack-L4T-3.1-linux-x64.run resides, I cannot see any .dtb files. I can find some under 64_TX:

So, I can see some .dtb files in the directories where they are supposed to be copied. Am I misunderstanding something?

@Alexey-Kamenev Thanks for the hint.
Can you clarify also the following:

• Should I apply only the latest TX2 patch (1.5) or all the patches starting from 1.2?
• The readme file for 1.5 contains instructions for making USB working and updating the device tree. Should I execute both? Sequentially or these can be done simultaneously?
• When patching, Jetson must be mounted on the original carrier board or on the J120?

Many thanks in advance

just verified, usb port on J120 with Jetpack3.2 doesn't work. don't know whether or not this patch will work
