(Notes: GPU and Codec were not incluided yet, will update later)
Target Debian OS Version: bullseye11.0
Target reference board: RZ/G2L,/G2LC,/G2UL SMARC
Host PC Environment: Ubuntu20.04
Debian Filesystem Building
Install QEMU
Run below command on Host Ubuntu PC
sudo apt-get install qemu qemu-user-static
Download Required Files
sudo apt-get install binfmt-support debootstrap
| Download debian package |
| $ sudo su - root # mkdir ./debian # cd ./debian # debootstrap --arch=arm64 --foreign bullseye root http://deb.debian.org/debian/ ### Notes: If you want to build Debian 10, you can use below command # debootstrap --arch=arm64 --foreign buster root http://deb.debian.org/debian/ |
This step requires network connection, if failed, please try more times.
If this step is successful, you can see below messages

Rootfs configuration
| Initialize rootfs |
| # cp /usr/bin/qemu-arm-static ./root/usr/bin # DEBIAN_FRONTEND=noninteractive DEBCONF_NONINTERACTIVE_SEEN=true LC_ALL=C LANGUAGE=C LANG=C chroot root debootstrap/debootstrap --second-stage |
If this step is successful, you can see below contents

| Additional Configuration |
| # cp -rf /etc/ssl root/etc ###copy certification from ubuntu pc to debian # chroot root # # apt-get update # apt-get install vim openssh-server # apt install net-tools iputils-ping bash bzip2 # vi /etc/ssh/sshd_config change #PermitRootLogin prohibit-password to PermitRootLogin yes # adduser user ### input password according to the hint # passwd root ### change root password # echo "auto eth0" > /etc/network/interfaces.d/eth0 # echo "iface eth0 inet dhcp" >> /etc/network/interfaces.d/eth0 # vi /etc/ssh/sshd_config # exit |
Compress rootfs
| # cd root # tar -cjf debian_bullseye_rootfs.tar.bz2 ./* |
Use debian_bullseye_rootfs.tar.bz2 to make sd card image (ignore)
