prepare-hypriot-emu

Ubuntu script to prepare a hypriot disk image for running under qemu

• include enlargement of image and adjustment of filesystem
• using only raw ubuntu tools to keep dependencies minimal
• Dockerfile nicely provided if you are on non Ubuntu system, but must use --privileged=true

Tested on hypriot v1.1.3 public image

Parameters are

1. -i IMG - path in docker (so you may need to mount image folder somewhere within docker container)
2. -s size - in human readable form (1M, 8G, etc)
3. -s hostname

docker run --privileged=true -v $(pwd)/images:/usr/rpi/images duquesnay/prepare-hypriot-emu -i images/hypriotos-rpi-v1.1.3.img -s 8G -h hostname

Then run it with qemu, something like

APPEND_ARGS="root=/dev/sda2 panic=1 rw loglevel=8 console=ttyAMA0,115200"
qemu-system-arm   -cpu arm1176   -m 256   -M versatilepb \
	-no-reboot   -serial stdio   \
	-append "${APPEND_ARGS}" \
	-kernel kernel/kernel-qemu-4.4.34-jessie \
	-net nic -net user,restrict=off  \
	-drive file=$(pwd)/images/hypriotos-rpi-v1.1.3.img,index=0,media=disk,format=raw

(here : command for MacOS; require downloading proper kernel for your distrib like kernel-qemu-4.4.34-jessie in this case; network access unrestricted... tune to your own needs)
