Custom images

Build image with Packer, QEMU and Ansible

Finally, burn it onto SD card

Requirements

• packer
• qemu
• ansible
• parted

Raspberry Pi 2

Build image

This is based on the qemu Packer builder

Build the image with command:

packer init .
packer build -force -only=qemu.armv7 .

Image should be generated at dist/armv7/archlinux-armv7.img

Test image

qemu-system-arm \
  -M raspi2b \
  -dtb dist/armv7/bcm2709-rpi-2-b.dtb \
  -kernel dist/armv7/kernel7.img \
  -initrd dist/armv7/initramfs-linux.img \
  -append "console=ttyAMA0 root=/dev/mmcblk0p2 rw rootwait systemd.default_device_timeout_sec=600s" \
  -drive "format=raw,file=dist/armv7/archlinux-raspberry-armv7.img" \
  -nographic

A prompt may apppear after a while
