Info for buildR64arch, all editions. This post may be corrected amended at any time.
https://github.com/ericwoud/buildR64arch
Currently supported boards: R64, R3, R3mini, R4.
Supported OS: ArchLinux-ARM and Ubuntu
The entire image is build around packages. All custom packages have .deb and .pkg.tar.xz versions for Ubuntu and Archlinux. The major difference (specially on headless systems) between Archlinux and Debian is the package manager. Other differences are really small. This makes the images for ArchLinux-ARM and Ubuntu almost identical. Because library versions can differ, all custom executables are build statically with musl, not depending on any library.
- bpirXX-atf-git package contains ATF binairies, command needed for writing. Customized all-in-one (bl2 + bl31), booting U-Boot or linux from fip- or fat32-boot partition.
- bpirXX-uboot-git package contains U-Boot binairies, command needed for writing. Customized to boot from extlinux conf or boot.scr.
- linux-bpirXX-git package contains kernel, automatically written when upgrading. Multiple linux kernel packages can be installed.
- hostapd-launch: helper for hostapd.conf, adding interface specifying bridge vlan id. Also implements bash substitution inside the .conf file.
- ssh-fix-reboot: shutdown ssh session quickly at reboot
The entire system has had a major overhaul, so some bugs may need to be ironed out.

Command available from build-host as ./build.sh or from board as bpir-build in linux and initramfs. It is mostly menu driven.
Usage: bpir-build [OPTION]...
-F --format format sd/emmc or image-file
-l --loopdev create file using loopdev instead of sd-card
-n --noroot create file without root acces instead of sd-card
-r --rootfs setup rootfs on image
-c --chroot enter chroot on image
-b --backup backup rootfs
-B --restore restore rootfs
-i --createimage create bpir.img, when using --noroot
-x --createxz create bpir.img.xz
-z --creategz create bpir.img.gz
-u --uartboot create uartboot image
-d --cachedir store packages in cachedir
-R --clearrootfs empty rootfs
-N --removenoroot remove directories created with --noroot
-S --disable-sandbox disable sandbox for kernels not supporting landlock
--imagefile [FILENAME] image file name, default bpir.img
--imagesize [FILESIZE] image file size in Mib, default 7456
--rootstart [ROOTSTART] sd/emmc: root partition start in MiB, default 256
--rootend [ROOTEND] sd/emmc: root partition end in MiB or %, default 100%
--brlanip [default|IP] ip for brlan
--ddrsize [default|8] ddr size in GB
--setup [AP|RT|...] setup for network
--target [bpir64|bpir3|bpir3m|bpir4] specify target
--device [sdmmc|emmc|nvme|sata] specify device
Start with --format to format a sdcard/image.
Use --loopdev to create an image instead of using a sd-card directly.
Use --cachedir when trying multiple times, but not downloading packages multiple times.
After building use --chroot (with --loopdev) to enter the image and do some more setting up manually.
Custom commands available from board in linux and initramfs (and uartboot):
Usage: bpir-toolbox [OPTION]...
--default-bootcfg Restore default bootcfg, adds --write2fip
--fip2boot Convert fip partition to boot partition bootchain (sd/emmc)
--boot2fip Convert boot partition to fip partition bootchain (sd/emmc)
--download2root Download files needed for nand-image (when started from initrd)
--nand-force-erase Force erase nand, including bad blocks and wear history
--nand-format Format the nand, also runs update
--nand-image Create nand image, also runs update
--nand-update Updates all files on nand, only writes when needed
--write2dtb Combine dtbos with dtb and create one dtb file
--write2atf Write arm-trusted-firmware
--write2fip Create all files needed for fip and write it, adds --write2dtb
--write2extlinux Create a new /boot/extlinux/extlinux.conf
--uboot-install Copies U-Boot to /boot/u-boot.bin (writes to fip if necessary),
also creates /boot/extlinux/extlinux.conf if not present
--uboot-remove Removes /boot/u-boot.bin
--uartboot Create a uartboot image
--pkgbase ... Specify linuxpkg to create files for
--set-atf-linuxpkg Set linuxpkg atf will directly boot, specified in pkgbase
--remove-dtb Remove dtb file
Usage: bpir-rootfs [OPTION]...
-i --brlanip [IP] specify ip for brlan
-d --ddrsize [default|8] specify ddr size
-s --setup [AP|RT|...] specify setup for network
-t --target [bpir64|bpir3|bpir3m|bpir4] specify target
--device [sdmmc|emmc|nvme|sata] specify device
-S --disable-sandbox disable pacman sandbox download
-n --noask Don't ask to alter rootfs and reset passwords and root access
-u --adduser [USER] add user named USER
-m --menuonly menu only
bpir-rootfs is menu-driven, arguments can be used instead.
Usage: bpir-initrd [OPTION]...
-p --preset [PRESET] specify preset
-P --allpresets build all presets
-m --modulesonly build only when image holds modules
All other linux commands available, including fiptool.
Commands available from board in initramfs (and uartboot):
bpir-dhcpc <interface>
bpir-synctime
bpir-build
bpir-toolbox
reboot
bash, debootstrap, nano, parted, etc
Building your own version of ATF, U-Boot or linux-kernel:
Basically all custom ATF, U-Boot or linux-kernel packages are build on Archlinux (aarch64 or x86_64). It can be done on a archlinux-chroot if preferred. Use https://github.com/tokland/arch-bootstrap to setup an archlinux chroot on a debian system.
After running makepkg, run makedeb to create the .deb (and possibly update a repo). See: makedeb
Support to install linux-image.deb created with other tool when running on Ubuntu is also implemented, but hardly tested (also supporting to extract Image from .itb from the package).
