I tried so many methods, some didn’t work, some didn’t fit, and some were too complicated.
Which one definitely works on Jetpack 4.6.4, and what is the easy one. Help please!
Can I backup my SD card with Win32DiskImager?
Any “clone” program should work. My experience though is with Linux.
Just to add some information, as used in Jetsons, the SD card has a partition. A clone of the partition itself should allow recreation of the partition on another SD card, or saved as a file for later use on a host PC. It’s just binary data.
Surrounding each partition though is a partition scheme. The modern scheme is GPT, the old one is BIOS. This includes metadata about the partitions, and sometimes boot metadata (not used for Jetsons). If you clone an SD card as a whole, and not just a partition, then you could expect the recipient SD card of a clone to look like the original SD card. That includes various IDs, and sizes. So for example, if you cloned an SD card as a whole which is 32 GB, and restore it to a 64 GB SD card, then the 64 GB will look like a 32 GB until adjustments are made. If instead you had worked with a 32 GB partition clone, then it is possible that your 64 GB restore recipient would show the original 32 GB partition, but also would show the remaining SD card space as free space.
In reality, if your SD cards are the same size, then I’d just clone the whole SD card, but if you will be working with SD cards of different sizes, then I’d probably work with partition images instead of the SD card as a whole. Sorry, I don’t know what to work with under Windows for that, but if it is an imaging program, then give it a try and see what happens (use a blank or unimportant SD card recipient and your original should be left alone).
So can I do this on the Xavier Nx and 4.6.4 ?
There are differences in different models. This particular forum is for the older Nano. If this is the Xavier NX, then it is similar, but not exactly the same. Be sure to specify if this is a Nano or Xavier NX. If it is an NX, then also be sure to specify if this is an eMMC model, or if it is a purely SD card model (the instructions are quite different for the two models).
That depends what you mean. A true clone requires the SD card to be read-only. You can do things which come close, such as manual partitioning and rsync. What is your destination media? Is it also an SD card, and do you want to mount this on an extra SD card USB reader on the same Xavier NX that you are backing up? There are also methods to do the same with rsync over ssh, e.g., from a Jetson to a host PC over the network.
To partially clarify, there are essentially two different models possible of the small form factor Jetsons:
- A dev kit whereby there is no eMMC, and the SD card is mounted on the module itself. This would also have QSPI memory on the module itself containing boot code and the equivalent of a BIOS.
- An eMMC model, whereby a third party manufactures the carrier board, and any SD card is on the carrier board, not the module.
Is this an Xavier NX, or is it a Nano? Is this an eMMC model, or an SD card dev kit model? It seems that the source of the clone is an SD card, but what is the destination? Is the destination an exact match of the source, or is there a difference in size?
