@joko @dezgeg @grahamc (and anyone else in to ARM hardware) I visited Firefly’s office and met with their management today. They are very friendly and keen to develop distribution of their Rockchip-based ARM64 boards outside of China. For this purpose they said they are willing to send free hardware to open source developers in exchange for documenting and enhancing distribution-specific support for their boards. As far as I can tell, they use standard Rockchip u-boot, and I have had success flashing Android and Ubuntu images so far using the Rockchip Linux flash tool. If you would like to receive a board, please let me know your address via private message and I will pass your details along.
They also showed me a really cool 60-core fanless ARM64 cluster board (private development; not yet released)… might be a great future target for Nixops.
