PKGBUILD files and other bits and pieces to get Arch Linux running on Jetson Nano

This is a work in progress, mostly made for my own notes, I cannot guarantee it won't brick your nano

Rough steps to get arch booting on nano are:

On a host PC (currently only tested on Ubuntu)

• Download the generic Arch armv8 distribution from: https://archlinuxarm.org/platforms/armv8/generic
• Download the Jetson Nano driver package https://developer.nvidia.com/embedded/linux-tegra-r3273
• extract the driver package, then extract the Arch distribution into Linux_for_Tegra/rootfs
• mkdir rootfs/boot/extlinux.conf
• sudo cp bootloader/extlinux.conf rootfs/boot/extlinux/extlinux.conf
• put your nano into recovery mode (either via jumper, or via sudo reboot --force forced-recovery if you already have ubuntu running)
• run ./nvflash.sh <board> mmcblk0p1 where is the name of one of jetson-nano*.conf (minus the .conf), or ./nvautoflash.sh to autodetect the board.
• For more on flashing, check out the docs at https://docs.nvidia.com/jetson/archives/l4t-archived/l4t-3261/index.html#page/Tegra%20Linux%20Driver%20Package%20Development%20Guide/flashing.html

Once the flashing is done, you should be able to reboot into Arch.

Initialize the pacman keyring and populate the Arch Linux ARM package signing keys

pacman-key --init
pacman-key --populate archlinuxarm

The nvflash tool replaced the linux-aarch64 kernel with the L4T kernel, and if you pacman -Syu at this point, it will overwrite the kernel.

• Uninstall linux-aarch64 kernel, which will delete the L4T kernel image
• Re-install the L4T kernel

pacman -R linux-aarch64
pacman -Syu
pacman -S git

Then clone this repo, and install (makepkg --syncdeps then pacman -U) at least nvidia-l4t-core, nvidia-l4t-tools, nvidia-l4t-init, nvidia-l4t-firmware and nvidia-l4t-kernel.

At this point you should be safe to reboot, and further set up your system however you want.
