Build script to build a Debian 12 image for FriendlyELEC NanoPi RK3328 based boards, as well as all dependencies. This includes the following:

• Mainline Linux Kernel - linux-6.7.y
• Arm Trusted Firmware - arm-trusted-firmware/master branch
• Mainline U-Boot - v2024.04-rc3

Note that there are patches/modifications applied to the kernel and u-boot. The changes made can be seen in the ./patches and ./overlay directories. Also, a ./downloads directory is generated to store a copy of the toolchain during the first build.

Currently images for the following devices are generated:

• FriendlyELEC NanoPi Neo3
• FriendlyELEC NanoPi R2S

• The following packages below are required to use this build script. Note that this repo uses a Dockerfile to handle most of the heavy lifting, but some system requirements still exist.

docker-ce losetup wget sudo make qemu-user-static

Note that without qemu-user-static, debootstrap will fail!

• Just run make.
• Completed builds output to ./output
• To cleanup and clear all builds, run make clean

Other helpful commands:

• Have a build fail and have stale mounts? make mountclean
• Want to delete the download cache and do a 100% fresh build? make distclean

• Take your completed image from ./output and extract it with gunzip
• Flash directly to an SD card. Example: dd if=./neo3*.img of=/dev/mmcblk0 bs=4M conv=fdatasync

• You tell me. Bug reports and PRs welcome!

• This is a pet project that can change rapidly. Production use is not advised. Please only proceed if you know what you are doing!
