{{ARM/breadcrumb}}
We now have https://github.com/novena-next/nixos-novena repository that can be used to build Novena specific kernel and few other tools like <code>novena-eeprom</code> and <code>novena-usb-hub</code>.

Also check out https://github.com/novena-next/docs for general purpose documentation. This guide might move there at some point.

=== Using generic image ===

[[NixOS on ARM]]

use generic <code>armv7l</code> image (<code>sd-image-armv7l-linux.img</code>)

=== U-boot ===

Build u-boot according to

[[NixOS_on_ARM#Building_u-boot_from_your_NixOS_PC]]

{{commands|<nowiki>
make novena_defconfig
</nowiki>}}  

{{commands|<nowiki>
dd if=SPL of=/dev/sdc seek=1 bs=1k
</nowiki>}}  

Store <code>u-boot.bin</code> on <code>/boot</code> (mounted sd-image).

Proceed with standard installation steps and 
[[NixOS_on_ARM#Building_U-Boot_from_your_NixOS_PC]]

You can use your own layout when installing on the hard drive (SD-card is still needed to boot from SATA), <code>extlinux</code> insted of <code>grub</code> is important.

=== Configuring SATA boot ===

To enable booting from SATA by default enable <code>sataroot</code> feature with <code>novena-eeprom</code> and then break to u-boot shell and run following commands to set different boot order:

TODO: disk ID

{{commands|<nowiki>
printenv
setenv boot_targets sata0
saveenv
reset
</nowiki>}}
