Linux BSP User Guide for jetson series
Contents
Linux BSP Version
Ubuntu 18.04
Kernel 4.9.201
Released Image
Build Environment on Host
Currently, we adopt Docker as build environment.
You can get the latest version of advrisc/u18.04-imx8lbv1 Docker image for developing nVidia jetson projects.
Docker command:
$ docker pull advrisc/u18.04-imx8lbv1
Run Docker example
Step1 Run docker container (example)
sudo docker run -it --name jetson_linux_risc -v /home/bsp/myLinux:/home/adv/BSP:rw --privileged advrisc/u18.04-imx8lbv1:latest /bin/bash
Step2 In container, change the user. (example)
adv@7cc0fa834366:~$ sudo chown adv:adv -R BSP
Dependncy Library
Please install library in the HOST outside of docker if you get Exec format error.
$sudo apt-get install qemu-user-static
