Prebuilt images are available on the releases page (for tested images) or development images are available via the github actions page
Two images are currently build - A minimal image - sdcard-pine64_0x64_defconfig and a more complete image - sdcard-pine64_0x64_full_defconfig
The SD card images are configured with a 1Gb Swap Partition, and will resize the rootfs partition on first boot to the full size of the SD card.
Inside the downloads you will find the following files:
- m0_lowload_bl808_m0.bin - This firmware runs on M0 and forwards interupts to the D0 for several peripherals
- d0_lowload_bl808_d0.bin - This is a very basic bootloader that loads opensbi, the kernel and dts files into ram
- pine64-ox64-firmware.bin/sispeed-m1s-firmware.bin - A image containing OpenSBI, the Kernel and DTS files for Pine64 OX64 and SiSpeed M1S Dock
- sdcard-*.tar.xz - A tarball containing the rootfs for the image to be flashed to the SD card

Buildroot provides a "SDK" for the baords. This is a tarball containing the cross compiler and sysroot for the target board. This can be used to compile applications for the board. Please refer to https://github.com/openbouffalo/buildroot_bouffalo/wiki/Building-Programs-outside-of-buildroot for basic instructions (or consult the buildroot documentation)
Please refer to the projects tab for the status of drivers in development.
Please use the github discussions for any questions or issues.
