Is it possible to boot L4T from a USB 3 disk on the Jetson Nano? If so, how? I have tried copying (using rsync -rav) everything from the root partition of the nano SD card image onto an ext4 formatted SSD connected to my nano via a SATA3 → USB3 adapter and I modified the extlinux config file to use…

I wrote to the NVIDIA engineers/devs to get the definitive status on this: On Fri, Mar 29, 2019 at 02:12:09PM +0000, Dan MacDonald wrote: Hi Thierry I got my Jetson Nano a few days ago. I’ve not had much time to use it yet but I’m hoping I will this weekend. It’s looking good so far. The first…

As for the rootfs, in the “Setting up your file system” section of the Linux Driver Package Development Guide: https://docs.nvidia.com/jetson/l4t/index.html#page/Tegra%2520Linux%2520Driver%2520Package%2520Development%2520Guide%2Frootfs_custom.html%23 It says: “Navigate to the rootfs directory of …

“Linux_for_Tegra/” is on the Ubuntu desktop host PC used for flashing. You won’t find that on any of the embedded systems. This file is actually created by the driver package, which in turn would be installed if JetPack ran…and I think the SDK Manager would download and run that. Basically a front e…

I’m afraid the bootcode cann’t jump correctly into the USB storage. For the Rootfs part maybe it’s ok. You can see there are some other partitions used in the eary boot.

Anybody manage to get a an installation up and running on a usb3 drive? The sdcard is incredibly slow.

You sort of can but you will need to recompile the kernel and include the tegra usb firmware as well as leaving /boot on the sd card. The rest of the rootfs can be moved to a usb drive.

Have you gotten it to work yet?

Yes, using the method I described.

That’s awesome. Any chance you could do a little write up on how you did it? Even if it were in just a pastebin text file. Like what you changed when recompiling the kernel, how you specified to it to point to the external drive ect…

Would love a short (not that short) howto, too. I got mine running with /home and swap on the USB3 SSD. This is better, but could get some more improvement. Here’s the /etc/fstab I used for this: /dev/root / ext4 defaults 0 1 UUID=b8aace4a-94d5-417e-a15a-a0be904c7b71 /home ext4 defaults 0 …

Just FYI, if you have a booted system, then you can find UUID (and other useful information) via: lsblk -f

That blog post seems to cover the approach in detail, the zswap change also looks interesting. Thank you for sharing.
