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
