I have just flashed a new TX2i with L4T R32.3.1, but none of the python scripts for overlay generation appear to work. There doesn’t appear to be a board description matching the Tx2i (3489-0000) in /opt/nvidia/jetson-io/Jetson/boards. Any suggestions?
Did you check this doc?
Yes, I’ve been over that document. It didn’t mention any exclusion for the TX2i.
I think it should be the same with TX2 (p2597-0000+p3310-1000.board)
What’s command to repo and any error message?
Debugging statements in /opt/nvidia/jetson-io/Jetson/ board.py, showed that all of the scripts fail for the same reason, being that board.py can’t find p2597-0000+p3489-0000.board in the Jetson/boards directory.
sudo ./config-by-hardware.py -l

I suppose if I hacked the scripts to generate the compatibility string for a TX2, then I might be able to use them, because as you say, the hardware is similar enough, but I think this could cause other problems?
Hello!
I can confirm that TX2i is not supported. Are you using the TX2i module with the DevKit carrier board or some other carrier board?

I have my TX2i plugged into a Devkit carrier board.
Given the absence of those tools for pinmux and DT configuration (which is a big shame), could you point me at a definitive guide to updating the DT with R32.3.1? I’ve read that flashing isn’t strictly necessary any more, even with a recompiled kernel. Is that correct?
Check this link for update dtb by dd command. The kernel Image you can just copy the Image and modify the /boot/extlinux/extlinux.conf to load customize kernel.
Thanks,
Do you think the python scripts might get updated to support Tx2i?
Sorry, I don’t understand well your question.
This script should update if have issue and need new support.
johnathanh has confirmed that the scripts do not support the TX2i
OK, I thought you are talking about the flash.sh script.
For the jetson-io there’s no plan now.
Hello!
To configure the pinmux you should use the pinmux spreadsheet for TX2 [0] and then convert the generate DTSI files into the MB1 files as described here [1].
The kernel image and DTB can be loaded from the rootfs via the /boot/extlinux/extlinux.conf file. By default the kernel image is loaded from /boot/Image but the DTB is still loaded from flash. So unless you update the extlinux.conf to load the DTB from the rootfs, you still need to flash it.

[1] Where To Put Pinmux Spreadsheet DTSI Files
Hello!
At the moment there are no current plans. It should be noted that the jetson-io tool only configures the pinmux for pins exposed by the 40-pin header and that is why only the DevKit platforms are supported. We did not add support for the TX2i modules + DevKit carrier board, because we expect a lot of people using the TX2i modules, will in the long term, be creating their own custom carrrier board and hence need to configure the entire pinmux.

Jon
