== Status ==

NixOS on ARM through QEMU is possible, by using qemu-system-arm on QEMU's 'virt' machine, and the u-boot image for qemu.

{{note| [[https://lists.denx.de/pipermail/u-boot/2017-October/308693.html u-boot currently requires highmem=off for PCI to work]], so you won't be able to use more than 2GB of RAM .}}

== Board-specific installation notes ==

=== Required images ===
First get some recent sd-image-armv7l-linux.img and uboot-qemu_arm_defconfig-*_u-boot.bin as described [[NixOS_on_ARM|here]].

=== Creating qcow image ===
Convert the sd card image to qcow, and resize it a bit:

<syntaxhighlight>
qemu-img convert -f raw -O qcow2 sd-image-armv7l-linux.img sd-image-armv7l-linux.qcow2
qemu-img resize sd-image-armv7l-linux.qcow2 +5G
</syntaxhighlight>

== Booting using qemu ==
The following command will boot QEMU's 'virt' machine with u-boot and the converted sdcard image, exposing four cpu cores a:

<syntaxhighlight>
qemu-system-arm -machine virt,highmem=off -bios uboot-qemu_arm_defconfig-2018.03_u-boot.bin -drive if=none,file=sd-image-armv7l-linux.qcow2,id=mydisk -device ich9-ahci,id=ahci -device ide-drive,drive=mydisk,bus=ahci.0 -netdev user,id=net0 -device virtio-net-pci,netdev=net0 -nographic -smp 2 -m 10G
