Scripts to build images for the nvidia Jetson devices

Ubuntu Core for Jetson TX1/TX2/Nano/Xavier

This repository contains scripts to create a tarball with all what is needed to flash Ubuntu Core 18 in a Jetson TX1/TX2/Nano/Xavier device.

Build instructions

First, you will need to build the kernel and gadget snaps for the device. For that, clone the following repos and follow the instructions in the respective README.md files:

https://github.com/alfonsosanchezbeato/jetson-kernel-snap https://github.com/alfonsosanchezbeato/jetson-gadget-snap

Then, install ubuntu-image with

snap install --edge ubuntu-image

(we need to use the edge channel for the moment for xavier images).

Once you have created the snaps, you can create an installation tarball by running

./build-core.sh <tx1|tx2|nano|xavier> <snap_account_id> <gadget_snap_file> <kernel_snap_file> [key_name]

The snap account id can be found in your account details in https://dashboard.snapcraft.io. You will need an Ubuntu One account for this. You will also need a key registered with snapcraft to be able to create a model for the device. The key name parameter is necessary only if different from default.

After building, you will find a file named out-<tx1|tx2|nano|xavier>/core-18-jetson-<tx1|tx2|nano|xavier>.tar.xz that contains instructions and all needed files to flash UC18 into the device.

You can also download the latest tarball from the releases tab.

jetson-ubuntu-core's Issues

Update to latest SDK

Hello! Thank you very much for providing this port!

I've followed your posts and was able to build the UC image just fine even thought it is only working on a real Ubuntu 18 machine/VM with Snapcraft on it, and with the latest snapcraft it requires us to use --destructive-mode otherwise it would never cross-compile it.

The SDK being used is very old and I was trying to change it to make it work on the current SDK 32.4.3. However, I'm failing to get it to work because the source_sync.sh scripts takes 1 single tag for all the nvidia repos it will clone.

An example of this is the BCT repo:

Downloading default hardware/nvidia/platform/t19x/galen/bct source...

Couldn't find tag tegra-l4t-r32.4.3
/home/guto/uc-test/jetson-kernel-snap/nano/parts/kernel/src/sources/hardware/nvidia/platform/t19x/galen/bct source sync to tag tegra-l4t-r32.4.3 failed!

All the other repos that are part of the kernel snap are synced and have that 32.4.3 tag on them but the BCT doesn't.

Also, even using your repo without any changes, it looks like the NVidia libraries are not installed on the final image making it unusable to run things that leverage CUDA or the NVidia Container Runtime on it.

I was about to submit a PR against each repo updating them but I got stuck on it.

Do you have any idea what can be done to get it to work?

Thanks!

Compatibility with Jetson TK1

Hello
Thanks for this useful repo
I want to ask if it is possible to port Ubuntu Core on Jetson TK1?
Can I use the tarball of TX1 to flash the TK1?

Thanks in advance

Compatability with Jetson AGX Xavier

This is a great project! Would it be possible to add support for the Jetson AGX Xavier?

flash script question

I'm trying to flash the SD card on a Jetson Xavier NX using the latest release. After starting the device in recover mode, patched the files needed based on the released README, I executed the sudo ./flash.sh ... command. Regardless if I use -r or not flashing fails with different reasons. Here are the error messages I'm getting for both versions of the command.

1. sudo ./flash.sh jetson-xavier mmcblk0p1:

Failed flashing t186ref.

My system run Ubuntu 18.04 as a base and I am able to flash the device through NVIDIA's SDK manager. So is there a way for me to understand what am I doing wrong? Also is the ethernet connection a requirement for the flashing procedure to start or is it just for the first boot?

Thank you
