Maixduino and Kendryte k210 datasheets

Hello friends,

Do you know if a decent datasheet is available for the Maixduino board and the k210 chip?

I’m aware of this one [1] [2] but it is not very helpful. It has just a superficial description of the chip components.

I want to write some bare-metal code to learn how this chip works but it seems I’ll need to rely on reading the sources of the Kendryte SDK to find what I want.

Thanks in advance.
