Documentation
The documentation for the QuartzPro64 board and most of the documentation for the chips it uses hasn’t been publicly released yet, but if you do own a QuartzPro64 board, the users CounterPillow and Dsimic will happily provide the documentation to you for the research or development purposes, if you ask them in the PINE64 chat channels. We’ve got the following documents, some of which can also be found elsewhere on the Internet rather easily:
RK3588 datasheet
RK3588 technical reference manual (TRM), parts 1 and 2
RK3588 hardware design guide, machine translated to English from Chinese, and the original version in Chinese
RK860 datasheet, including register descriptions
RK806 datasheet, including register descriptions
AMPAK AP6275P (Wi-Fi and Bluetooth module) datasheet
