Linux BSP Version

Ubuntu 18.04
Kernel 4.9.201

Released Image

• OS Support List ( Jetpack 4.5.1 / L4T R32.5.1 )

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

Build Image - AIR-020 / EPC-R7200

Build Release Image

sudo ./scripts/build_release.sh -s <SOC> -v <VERSION>
Where
"-v : Image version" 00001~99999
"-s : 186 - Jetson TX2 NX"
"   : 194 - Jetson Xavier NX"
"   : 210 - Jetson Nano"

Build Kernel - AIR-020 / EPC-R7200

sudo ./scripts/build_kernel.sh -s <SOC> -v <VERSION>

nVidia : Build the Kernel

Enter Download Mode

Press following button + power ON, or

EPC-R7200	AIR020
]

Enter following command in the device,

$ sudo reboot --force forced-recovery

Flash Image

Make sure your Host PC has installed package : device-tree-compiler.
Before flashing the image, power off the DUT, press recovery button and power on.

AIR-030

sudo ./flash.sh -d rootfs/boot/tegra234-air030.dtb jetson-agx-orin-devkit mmcblk0p1

nVidia : Flash Support
Flash to NVME / SD directly
The nVidia provide another flash option : Flashing with initrd
Applies to: Jetson Xavier NX and Jetson AGX Xavier series only

Flash DTB

Flash Mac Address

GBE in eeprom

$ sudo ./eeprom $SOC $mac_address

Where SOC

  186 : TX2-NX
  194 : XavierNX
  210 : Nano 

Intel I210

$ 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.
