Create an image of Arch Linux to write onto a SD flash card or eMMC flash chip for the Star64 SBC. Try to do that using software that is typically available and keeping the product as close to upstream as possible. U-Boot is built for Starfive's VisionFive 2 board and the device tree is also for the VisionFive 2. The Star64 is not 100% compatible. The device tree could be updated and the kernel needs patching!
Run make to create an image file and use dd, Etcher, or so to install it.
Supplying a block device as as DEV_OR_IMG (e.g. make "DEV_OR_IMG=/dev/mmcblkX") will cause the image to be written directly to the block device.
This allows the root partition to use all available space, the amount of writes is reduced to a minimum because gaps don't have to be filled, and it's quicker.
In principle, it should be possible to create images for other distribution's as well. Maybe it's worth figuring out how to do that from this repo.
- util-linux
- subuid/subgid entries for the user running
make- only the first one is used
- range needs to be big enough to hold all files from the base file system
- 1000 should be enough but best be generous if possible (e.g. 10000) because tar doesn't stop (it only warns)
- qemu-riscv64-static and the respective binfmt rules (to allow running riscv64 programs in the chroot)
- enough RAM to hold the rootfs
- riscv64-linux-gnu-gcc
- U-Boot SPL with OpenSBI
- U-Boot payload (reads extlinux.conf)
- extlinux.conf generated by (packaged) libalpm hook
- Felix Yan's Arch Linux port for RISC-V (https://archriscv.felixc.at/)
The filesystem can be altered by adding customization scripts in rootfs-hook.d/.
Nothing stops you from calling sh from there and doing stuff interactively.
Remember to add the executable bit.
.env.rootfs-customization can be used to pass environment variables to the hooks.
The pre-existing scripts use these:
EDITOR
IMG_HOSTNAME
ROOT_PW
NO_ROOT_PW
ROOT_SSH_KEY
INSTALL_OPENSSH
KEEP_SSH_KBD_PW
- method to install tow-boot or EDK2 XSPI NOR
- makes this repo obsolete
- boot using EFI
I'm hesitant to publish a mode that creates an image for the SPI NOR flash. Details on how that is be done are in the table Flash Boot Address Allocation from the JH7110 Boot User Guide. The files can be created from here using make uboot.
