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
