Build Debian8 RootFS

Setup parameters

shell$ apt-get install qemu-user-static debootstrap binfmt-support
shell$ export targetdir=debian8-rootfs
shell$ export distro=jessie

Build the root file system in $targetdir(=debian8-rootfs)

shell$ mkdir $targetdir
shell$ sudo debootstrap --arch=armhf --foreign $distro                       $targetdir
shell$ sudo cp /usr/bin/qemu-arm-static                                      $targetdir/usr/bin
shell$ sudo cp /etc/resolv.conf                                              $targetdir/etc
shell$ sudo cp scripts/build-debian8-rootfs-with-qemu.sh                     $targetdir

Build debian8-rootfs with QEMU

Change Root to debian8-rootfs
shell$ sudo chroot $targetdir

There are two ways

  1. run build-debian8-rootfs-with-qemu.sh (easy)
  2. run this chapter step-by-step (annoying)
Setup APT
debian8-rootfs# distro=jessie
debian8-rootfs# export LANG=C

Setup hostname
debian8-rootfs# echo pynq > /etc/hostname
Setup root password
debian8-rootfs# passwd

This time, we set the "admin" at the root' password.

To be able to login as root from Zynq serial port.

debian8-rootfs# cat <<EOT >> /etc/securetty

Add a new guest user
debian8-rootfs# adduser fpga

This time, we set the "fpga" at the fpga'password.

debian8-rootfs# echo "fpga ALL=(ALL:ALL) ALL" > /etc/sudoers.d/fpga
Setup sshd config
debian8-rootfs# sed -i -e 's/#PasswordAuthentication/PasswordAuthentication/g' /etc/ssh/sshd_config
Setup Time Zone
debian8-rootfs# dpkg-reconfigure tzdata

or if noninteractive set to Asia/Tokyo

debian8-rootfs# echo "Asia/Tokyo" > /etc/timezone
debian8-rootfs# dpkg-reconfigure -f noninteractive tzdata
