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

Install Some tools

$sudo apt-get install expect

$ sudo -s
$ BDF=`lspci | grep 210 | awk '{print $1}'`
$ setpci -s $BDF COMMAND=0007

Get NIC

$./EepromAccessTool

Flash I210 address with mac_address = D4E5F6123456 ( If mac address = D4:E5:F6:12:34:56 )

$ ./EepromAccessTool -nic=<NIC> -f=Dev_Start_I210_Copper_NOMNG_8Mb_A2_3.25_0.03.hex -mac=$mac_address

Cold reboot the device.
