I had to deal with theses processors this weekend (Allwinner H3) for a side project (Pandora Box5 Jamma, an arcade system), the documentation is awful, i was unable to find the "real" SDK, the boot0 is a proprietary blob, but i found this awesome project https://linux-sunxi.org if you want to work with these kinds of processors.

You don't need an "SDK" for a general purpose computer. Always check mainline U-Boot and mainline OS (Linux, BSD) first. (For Linux, check distributions like Armbian and ArchLinuxARM.)

I don't think there's generally much reason to use Allwinner's boot0 on H3 or older, since mainline U-Boot has supported those chips for a couple of years now. In principle you can even just run Debian on them (though I don't think they build installer images for anything that new right now, and most people use Armbian for its better user experience).

Thanks ! i will look into it.

The Armbian guys have done a ton of excellent work in this area as well (they start with sunxi and take it the rest of the way)

This is intended to run Linux, its not a microcontroller-level device. The project you point to is the basis of what is in mainline (I believe now).

That’s right. I don’t think this is for RTOS.
