How can I get the datasheet of rock5B(RK3588)?

Request the datasheet of rock5B (RK3588) chip. I can’t download it from the download address on the official website(shows: 404 Not Found).

How can I get it ?

You can google it. Radxa cannot provide us this because Rockchip does not allow them to do so and Rockchip requested Radxa to remove the datasheet from their website.

it depends wich datasheet ?
