Hardware changes between SOM/board versions?

We have have been successfully using the Jetson TX2 NX module, Board ID(3636) version(300) sku(0001) revision(H.0) with a custom carrier board. However we are now receiving Board ID(3636) version(302) sku(0001) revision(C.0) and it now longer sees the SD card using the same carrier board. This appears to be related to an issue with a change in GPIO pins. Where can I find details on the changes between board revisions?

This isn’t exactly what you are looking for, but you might still be interested in (someone else will have to answer the question for what remains unanswered).

If you go to the flash software directory, which should be here:
~/nvidia/nvidia_sdk/JetPack...version.../Linux_for_Tegra/

Then run this command:
ls -l jetson*.conf

Note that all of those are flash targets if you remove the “.conf” on the end of the name. The actual flash file is a combination of the module model, the carrier board model, and sometimes revision. Within these there will be some specific configurations, but there will also be something like a C program’s #include statement. The configuration is built in steps. Someone with a custom carrier board probably uses the same module files, but some modified carrier board model for flash target when flashing on command line.

I would look, for that L4T release, at the flash targets. I would then look to see if there is any kind of revision number in the real file flash targets, and then what the changes are between those two files. If not in the file name, then I would be tempted to go through the chain of different files making up the module content (carrier board content might be irrelevant since the revision is for the module). Perhaps you can spot different specs for the two revisions via those files.

Thank you. You’re right it’s not exactly what I was asking for but it is quite helpful. Thanks.

Thank you. FYI, that link brings up the 404 page for me but I was able to find the document “Jetson TX1, TX2, Nano and Xavier PCNs” via search.
