Build Environment on Host

Currently, we adopt Docker as build environment.
You can get the latest version of advrisc/u20.04-nvlbv2 Docker image for developing nVidia jetson projects.
Docker command:

$ docker pull advrisc/u20.04-nvlbv2

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/u20.04-nvlbv2: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

$ cd ~/BSP
$ mkdir jetson_linux_risc
$ cd jetson_linux_risc
$ git config --global user.name "Your Name"
$ git config --global user.email you@example.com

For Jackpack 5.1.1:

1.Extracted tarball file

$  sudo tar -zxvf 7300A1AIM35UIVXXXXXX.tgz
$ cd Linux_for_Tegra

2. Flash

(1) To flash QSPI + NVME SSD:

$ sudo ./tools/kernel_flash/l4t_initrd_flash.sh --external-device nvme0n1p1 -c tools/kernel_flash/flash_l4t_external.xml -p "-c bootloader/t186ref/cfg/flash_t234_qspi.xml" --showlogs --network usb0 jetson-orin-epcr7300-a1 internal

(2) To flash only QSPI:

$ sudo ./flash.sh --no-systemimg -c bootloader/t186ref/cfg/flash_t234_qspi.xml jetson-orin-epcr7300-a1 mmcblk0p1

(3) To flash only NVMe SSD (Need to flash QSPI first):

$ sudo ./tools/kernel_flash/l4t_initrd_flash.sh --external-only --external-device nvme0n1p1 -c tools/kernel_flash/flash_l4t_external.xml --showlogs --network usb0 jetson-orin-epcr7300-a1 internal
