I modify some files in Linux_for_Tegra folder（kernel/rootfs etc） ， and I would like to upgrade my friend’s orin nx device in other city. how can I export some upgrade files and send to my friend? I don’t want to send all the Linux_for_Tegra folder, it cause like 40G+ size.
If you are both behind a router in a private LAN it is more difficult, but if either of you have the ability to ssh to the other’s system (directly), then you can use scp. I have not done this, but there are ways to create an ssh tunnel through a router to some common outside site if you have one. If you control the router, then you could set up port forwarding, but an ISP won’t give you that ability if you are not paying for a commercial account.
Last resort, you could put it in a thumb drive and use ordinary mail.
Not only the difficulty of sending the whole Linux_for_Tegra folder.
There are many other reasons:
#1 Tar and un tar the whole Linux_for_Tegra folder is a nightmare
#2 Do not want to share source code
#3 Export the images(kernel,dtb,system.img etc…) and upgrade script for upgrading is the simplest way ,like other platform such as:MTK,Rockchip
If two people use the same flash software release, and name the same target hardware, then you basically only need to trade the “rootfs/” subdirectory of “Linux_for_Tegra/”. If there is some other subset, then that would also reduce size. You haven’t specified exactly what it is you want to send, so right now the “rootfs/” content for flashing seems to be the answer. You should add much more detail on what you want to accomplish.
The real problem though seems to be how to transfer large content from one location to another, and email won’t work for that. You could use some sort of cloud sharing service, but if you can connect the two systems with something like ssh, then it becomes trivial (even if it takes a long time). You should add if you have ssh access across systems.
