# Image Builder for Archlinux on an Allwinner D1 / Sipeed Lichee RV
These scripts compile, copy, bake, unpack and flash a [ready](https://wiki.archlinux.org/title/installation_guide#Configure_the_system) to use RISC-V Archlinux.
*With "ready to use" i mean that it boots, you still need to configure everything!*

Special thanks to **smaeul** for all their work!

Find a **precompiled image** under the [Actions](https://github.com/sehraf/riscv-arch-image-builder/actions) artifacts. The image has _no_ configuration or whatsoever!

Also have a look at the forks that have emerged over time or similar projects like a [make file based approch](https://github.com/hyx0329/riscv-archlinux-d1).

## Starfive Vision 2
There are multiple sources for an Archlinux image:
- https://forum.rvspace.org/t/arch-linux-image-for-visionfive-2/1459
- https://github.com/thefossguy/archlinux-visionfive2

## Components
- mainline OpenSBI
- U-Boot based on https://github.com/smaeul/u-boot.git
- mainline kernel
- WiFi driver (rtl8723ds) based on https://github.com/lwfinger/rtl8723ds
- RootFS based on https://archriscv.felixc.at (root password is ~~`sifive`~~ `archriscv`)

## How to build
1. Install requirements: `pacman -Sy riscv64-linux-gnu-gcc swig cpio python3 python-setuptools base-devel bc`
1. If you want to `chroot` into the RISC-V image, you also need `arch-install-scripts qemu-user-static qemu-user-static-binfmt`
1. Edit `consts.sh` to your needs. For example, you may want to select a [different DTB](https://github.com/sehraf/riscv-arch-image-builder/blob/5c450da98d578617781ae13f9d2b0850a61b21c4/consts.sh#L22) for a different board variant.
1. Run `1_compile.sh` which compiles everything into the `output` folder.
1. Run `2_create_sd.sh /dev/` to flash everything on the SD card.
1. Configure your Archlinux :rocket:

## Using loop image file instead of a SD card
Simply loop it using `sudo losetup -f -P ` and then use `/dev/loopX` as the target device.

## Notes
The second script requires `arch-install-scripts`, `qemu-user-static-bin` (AUR) and `binfmt-qemu-static` (AUR) for an architectural chroot.
If you don't want to use/do this, change `USE_CHROOT` to `0` in `consts.sh`.
*Keep in mind, that this is just a extracted rootfs with **no** configuration. You probably want to update the system, install an editor and take care of network access/ssh*

Some commits are pinned, this means that in the future this script might stop working since often a git HEAD is checked out. This is intentional.

The second script uses `sudo` for root access. Like any random script from a random stranger from the internet, have a look at the code first and use at own risk!

Things are rebuild whenever the corresponding `output/` is missing. For example, the kernel is rebuilt when there is no `Image` file.

# Status

## 25.07.2023
- forgot to keep this up to date...
- mainline kernel fully supports the D1
- kernel updated to 6.4 (mainline)
- OpenSBI updated to 1.3

## 4.11.2022
- WiFi is working again

## 3.11.2022
- updated U-Boot and remove boot0 (handled by [U-Boot](https://github.com/smaeul/u-boot/releases/tag/d1-2022-10-31))
- updated kernel to 6.1.0-rc3
- **THIS BRAKES BUILT-IN WIFI**

## 13.09.2022
- kernel is back at 5.18-rc1 due to being more reliable

## 14.06.2022
- kernel updated to 5.19-rc1
- added initramfs support (untested)
- added extlinux support

## 22.04.2022
- kernel includes modules for USB LAN adapter
- swap is enabled
## 09.04.2022
- HDMI, tested with LXDE/LXDM
## 07.04.2022
- WiFi \o/
## 06.04.2022
- Kernel is based on 5.18-rc1
- WiFi driver fails to build (linking error :feelsbadman:)
- Both kernel and U-Boot are using `nezha_defconfig` since i found them more reliable
- With the [licheerv_linux_defconfig](https://andreas.welcomes-you.com/media/files/licheerv_linux_defconfig) from [here](https://andreas.welcomes-you.com/boot-sw-debian-risc-v-lichee-rv/) the kernel fails to find the sd card (or its partitions? not sure what exactly goes wrong)
- HDMI is not working (at least on the one screen i've tested it)

# Problems
## 06.04.2022
- ~no WiFi!~
- ~No HDMI (though, i'm unsure about the state of HDMI support in general)~
