Is Jtepack 4.6.3 compatible with Jetson orion nano developer’s kit?
No. That’s for the very old original Nano (which is a TX1). Here is a list of compatible releases:
https://developer.nvidia.com/linux-tegra
Note that Jetsons start with a purely Ubuntu filesystem, and then NVIDIA drivers are added; it is with the NVIDIA content that it is then called L4T. This is what gets flashed; JetPack/SDK Manager is normally tied to a given L4T release (by default, but you can use options to switch L4T release) as a GUI front end to the flash software. The newest L4T the old TX1 Nano can use is L4T R32.x; Orin started out with L4T R35.x, but it wasn’t really “complete” until R36.x (that’s just my opinion, not any kind of fact).
The L4T URLs will also lead to the JetPack/SDKM URLs, but you can look up directly via JetPack release as well:
https://developer.nvidia.com/embedded/jetpack-archive
but here it’s mentioned that Jetson nano works with it
oh
get it our’s is orio nano. Not just Jetson nano.
But the problem is coming with jetpack 6.0 which is acc. to this chart compatible with jetson orion nano, I’m not able to change the o/p of my GPIO pin.
Please help me with this!!!
Orin is a much different hardware and not compatible with non-Orin software (old Nano and Orin Nano are very very different).
There are indeed other “Nano” models, and yours is apparently not Orin and not Xavier. For the older Nano use the newest L4T R32.x:
https://developer.nvidia.com/embedded/linux-tegra-r3276
Download links in that URL are good for working with the older Nano. Also, JetPack can be told to list older releases. Use a host PC which is Ubuntu 18.04 (if not, then you might need to use older command line flash; the GUI has more restrictions on host release version than command line does). Older JetPack/SDK Manager has this option to start showing older releases of L4T:
sdkmanager --archivedersions
Newer releases use this:
sdkmanager --archived-versions
Note: I’m not sure if the JetPack 6.x can go all the way back to the JetPack 4.x content (which is for flashing L4T R32.x). If you need an older JetPack and for some reason the download is no longer there, then that can be fixed.
The above is for flash. You might be interested in this downloads URL for the older Nano, which includes some documentation and tools:
https://developer.nvidia.com/embedded/downloads#?tx=$product,jetson_nano
In particular, the PINMUX spreadsheet might be what you are interested in. You’d have to enable macros. See:
https://developer.nvidia.com/embedded/downloads#?search=pinmux&tx=$product,jetson_nano
There is also a utility within “/opt” (I forget the exact subdirectory) related to GPIO functions.
Several guides exist as well:

A web site which is quite useful is:
